10. How is Soil formed? What is Soil Erosion?
Answer:
soil is formed by weathering of rocks
soil erosion is the removal of the top soil by agents of erosion such as water, wind and ice
Soil is formed by various factors:
The Sun heats up rocks during the day so that they expand. At night, these rocks cool down and contract. Since all parts of the rock do not contract and expand at the same rate, this results in crack formation and huge rocks break up into smaller pieces.Water is another factor for soil formation. Water could get into the cracks in the rocks formed due to uneven heating by the Sun. If this water later freezes, it would cause the cracks to widen. Flowing water wears away even hard rock over long periods of time. Fast flowing water often carries big and small rock particles downstream. These rocks rub against each other and the resultant abrasion causes the rocks to wear into smaller and smaller particles. The water takes these particles along with it and deposits it further down its path. Soil is thus formed in places far away from its parent-rock.Wind also erode rocks down. The wind also sand from one place to the other.Living organisms also influence the formation of soil. The lichens grow on the rock surfaces. It releases certain substances that cause the rock surface to powder down and form a thin layer of soil. Other small particles like moss, are able to grow on this surface now and they cause the rock to break up further. The roots of big trees sometimes go into cracks in the rocks and as the roots grow bigger, the crack is forced bigger.Thus, soil is formed like this.Removal of the topsoil is known as the soil erosion.Hope you could get an idea from here.

How Can Regulation be Accomplished? Chemotaxis by Pseudomonas aeruginosa requires regulation of macromolecules in response to signals. Protein regulation is very important and can be grouped into two categories: those that are based on protein activity and those that are based on the amount of protein present ,write the type of regulation described that does not affect the amount of protein present.
1. regulating amount of mRNA made
2. catabolite repression
3. post-translational modification small RNA (sRNA) regulation regulation of transcription
4. attenuation controlling whether mRNA is translated
Answer:
3. post-translational modification small RNA (sRNA) regulation regulation of transcription
Explanation:
The post-translational modification does not affect the amount of protein present because this type of change is only done to the protein when the translation process has finished, and there is a protein as a result. After the translation, the final product can suffer modifications such as the addition of different components, or enzymatic modifications. In other words, they are chemical changes that the protein experiences that do not affect the amount of protein present.

Explanation:
Please describe the regulation of the blood glucose 6 hours after a meal?
Please include all relevant organs, hormones, and actions.
Answer:
Find the description below in the explanation section
Explanation:
The body system regulates the blood sugar level via the hand-in-hand working of insulin and glucagon hormones, both produced by the Pancreas. After a meal, the food undergoes digestion and is broken down into glucose, which is absorbed into the bloodstream. Insulin hormone is released by the pancreas (stimulated by a negative feedback) when the sugar level of the blood increases. This secretion of insulin causes cells to absorb glucose as source of energy, while liver and muscle cells store some of the excess blood glucose as GLYCOGEN.
However, after about 6 hours of taking the meal, the blood sugar (glucose) level must have decreased. This triggers the secretion of Glucagon hormone by the Pancreas. Glucagon hormone, acts in an opposite manner as Insulin hormone, by causing the stored GLYCOGEN in the liver and muscle cells to be converted back to Glucose in order for cells to make use of it.
This continuous process occurs and it is how the body regulates the blood glucose levels.
Some present-day bacteria use a system of anaerobic respiration characterized by an electron transport chain analogous to that found in aerobic organisms. Which of the following correctly characterizes the anaerobic electron transport chain?
a. It uses oxygen as a final electron acceptor.
b. It is embedded in the outer mitochondrial membrane rather than the inner mitochondrial membrane.
c. It establishes a proton gradient between the cytoplasm and the extracellular fluid.
d. It establishes a proton gradient between the intermembrane space and the cytoplasm.
e. None of these answer options accurately characterizes the anaerobic electron transport chain.
Answer:
The correct answer would be:
Neither of these response options accurately features the anaerobic electron transport chain.
Explanation:
The anaerobic respiration system vibrated by an electron transport chain is a mechanism that anaerobic bacteria have to maintain their respiration.
This mechanism does not require oxygen in the atmosphere, that is why it is said to be an anaerobic mechanism.
Bacteria do not all need oxygen in the environment to live, some need that oxygen is not exactly present (strict anaerobes) or that it is at low partial pressures (facultative anaerobes).
This mechanism is very characteristic in its location since it is located in the inner membrane of the mitochondria, that is why it will decide to indicate that option as the correct one.

the climax is the ___ stage of the community change
a) final
b) first
c) second
d) third
Climax is the final stage of community change. Option A is correct.
It is the stage at which the community reaches a state of equilibrium, with a balance of different species and a stable ecosystem. Primary succession is the process by which a community develops on a new or disturbed area. The first species to colonize the area are called pioneer species.
These species are able to survive in harsh conditions and help to prepare the area for the arrival of other species. Secondary succession is the process by which a community develops after a disturbance, such as a fire or a flood. The community will usually recover more quickly than in primary succession, as the soil and other resources will already be in place. The climax community is not static, but it can change over time due to factors such as climate change or human activity. Option A is correct.

(2) Atmosphere- (A) an increase in the level of CO₂ around the earth leads to climate change
(1) Hydrosphere- (B) the depth of an ocean increase as glaciers melt
(3) Geosphere- (C) the height of a mountain increases by 0.4 centimeters each year
(4) Biosphere- (D) infection with a fungal disease decreases the size of a bat colony
The atmosphere, hydrosphere, geosphere, and biosphere are the four major spheres or systems of the earth.
The atmosphere refers to the sum total of gases available on the earth. It makes the blanket of gases around the globe. Thus, an increase in carbon dioxide would come under the atmosphere
Hydrosphere refers to the total amount of water available on the surface of the earth. For example, seas, oceans, rivers, lake, underground water et cetera.
Geo means ground and thus geosphere refers to the total amount of ground, rocks, and minerals present on the earth. Thus, the increase in height of a mountain comes under the geosphere.
Biosphere refers to any space on earth which is occupied by any living organism (animals, plants, birds, microorganisms et cetera)

Answer:
The correct answer is "True".
Explanation:
The missing options of this question are "true" or "false" and in this case the correct answer is "true". According to the laws of inheritance established by Charles Darwin, the certain traits of species can be analyzed and studied by using crossing experiments. These experiments are performed first by analyzing the traits of each individual separately and second by observing the frequencies of each are combined to yield the observed phenotypic ratios. Different approaches are used to study the frequencies of each allele, and the most widely used is the punnet square approach.

The allosteric effector molecule 2,3-BPG facilitates transfer of oxygen between maternal and fetal blood in the placenta. Which of the following correctly describes the role of BPG in this process?
a. Fetal hemoglobin binds oxygen better than maternal hemoglobin because BPG is unable to cross the placenta into fetal blood, causing more fetal hemoglobin to be in the R state.
b. Fetal hemoglobin binds oxygen better than maternal hemoglobin because BPG is present at similar levels in fetal and maternal blood, but it binds poorly to fetal hemoglobin, causing more fetal hemoglobin to be in the R state.
c. Fetal hemoglobin binds oxygen better than maternal hemoglobin because BPG is present at similar levels in fetal and maternal blood, but it binds poorly to fetal hemoglobin, causing more fetal hemoglobin to be in the T state.
d. Fetal hemoglobin releases oxygen better than maternal hemoglobin because BPG is present at similar levels in fetal and maternal blood, but it binds more effectively to fetal hemoglobin causing more fetal hemoglobin to be in the T state.
Answer:
b. Fetal hemoglobin binds oxygen better than maternal hemoglobin because BPG is present at similar levels in fetal and maternal blood, but it binds poorly to fetal hemoglobin, causing more fetal hemoglobin to be in the R state.
Explanation:
BPG is a chemical compound which is found in red blood cells. It is known for decreasing the affinity of hemoglobin with oxygen and thus helps in unloading oxygen from hemoglobin.
Owing to the structural difference, fetal hemoglobin binds to BPG with less affinity as compared to maternal hemoglobin thus it shifts the oxyhemoglobin curve to the left i.e. causes fetal hemoglobin to be in the R state. Due to this, fetal hemoglobin can carry up to 30% more oxygen as compared to maternal hemoglobin. As a result of this, oxygen is readily transferred to fetal blood when maternal blood enters placenta which restricts hypoxia in fetus.

Explanation:
In 1668 Francesco Redi did a series of experiments on spontaneous generation. He began by putting similar pieces of meat into eight identical jars. Four jars were left open to the air, and four were sealed. He then did the same experiment with one variation: instead of sealing four of the jars completely, he covered them with gauze (the gauze will exclude the flies while allowing the meat to be exposed to air). In both experiments, he monitored the jars and recorded whether or not maggots (young flies) appeared in the meat.
Refer to the paragraph on Redi's experiments. In both experiments, fies appeared in all of the open jars and only in the open jars. Which one of the following statements is correct?
A. The experiment was inconclusive because it did not nun long enough
B. The experiment supports the hypothesis that spontaneous generation occurs in rotting meat.
C. The expertment supports the hwpothesis that maggots arise only from eggs laid by adult flhes
D. The experiment was inconclusive because Redi used only one kind of meat
Answer:
The experiment supports the hypothesis that maggots arise only from eggs laid by adult flies; that is only from reproduction and development.
Explanation:
The objective of this experimental set up by Francesco Radi was to demonstrate the concept of spontaneous generation. He concluded that, Maggots are not spontaneous generated from rotten meats, rather they are products of eggs laid by houseflies who visited the rotten meat to lay eggs. The maggots (larva) are products of complete metamorphosis, from egg to larva to pupa and adult. This is an indication that, new organisms are not formed form spontaneously, but are products of well-defined process of reproduction and development which in this case is a complete metamorphosis.
Based on this premise he concluded that, if maggots were products of laid eggs, then they should appear only when rotten meat is exposed to open air.However,if they are f products of spontaneous generation they should appear irrespective of the meat exposure to air or not.

7. Glyceral-3-phosphate
8. NADH
9. FADH2
10. Oxaloacetate
11. Water
12. Protons
Answer:
Explanation:
Pyruvate inflow; as this is needed to initiate the link reaction reactions that gives acetyl CoA. The latter enters the Kreb's cycle to provide the electrons carried in hydrogen atoms by NADH and FADH2 for ocidative phosphorylation for ATPs synthesis.
Oxygen Inflow, to accept the final electrons for the electron transport chains to continue.
Electron inflow ,carried in hydrogen atoms by NADH and FADH2 , to produced the electron transport chain, needed to generate the PMF.
ATP-outflow; this is the end product of the oxidative phosphorylation. it is synthesized by the ATPase synthase enzyme. using the energy from the electrochemical gradients.
ADP Inflow- it mus be phosphorylated by phosphate to form ATPs during synthesis, as catalysed by ATPase synthase.
Acetyl Co A. this is no net change,
Oxaloactate - no net change, the amount of this must remain contant in the kreb's Cylce, because of continuous formation from pyruvate.
NADH and FADH2 are co enzymes needed to ferry Hydrogen atoms into the matrix,to extract electrons.(inflow)
water is liberated from the matrix , therefore it goes out -from the reaction of oxygen and hydrogen (proton)in the matrix
Protons inflow into the intramembrane of the mitochondrial .
Glyceride -3-phosphate -no net flow, because it is further broken down to form pyruvate as it is continuous formed from phosphorylated glucose.

f. Myosin head is re-energized
g. Calcium ion concentration decreases below the threshold for binding to troponin
h. ATP attaches to myosin head
Answer:
Explanation:
This is the process of muscle contraction and relaxation in the muscle. The type of muscle involved is the skeleton muscle.
The process is initiated in the Central nervous system. Examples are in contraction of biceps and triceps.
It involves myosin head and actin filament coupled with the release of calcium ion from the sarcoplasm reticulum: this ion activates this process in the muscles. With the exposure of the music binding site on the acting filament, myosin is able to bind to acting filament bringing about this process.
a. ATP attaches to myosin head
b. Myosin head is re-energized
c. Myosin head forms cross bridge with actin
d. Power stroke moves thin filament
e. Cross bridges detach from actin
f. Myosin binding sites covered
g. Calcium ions pumped into the sarcoplasmic reticulum
h. Calcium ion concentration decreases below the threshold for binding to troponin.
Muscle contraction results from the interaction between actin and myosin filament proteins.
During muscle contraction, ATP binds to myosin, which passes to a high-energy state and it allows actin and myosin to detach from each other.The sarcoplasmic reticulum (SR) is a specialized type of endoplasmic reticulum in muscle cells that acts to regulate the concentration of cytosolic calcium (Ca2+).The sequential steps are as follow:
Myosin head forms cross bridge with actinPower stroke moves thin filamentATP attaches to myosin headCross bridges detach from actinMyosin head is re-energizedCalcium ions pumped into the sarcoplasmic reticulumCalcium ion concentration decreases below the threshold for binding to troponinMyosin binding sites coveredIn conclusion, muscle contraction results from the interaction between actin and myosin filament proteins.

At the neuromuscular junction, _______ must enter the synaptic end bulb to stimulate the release of ____________, which binds to ligand gates so ________ can enter the muscle fiber.
Answer:
At the neuromuscular junction, calcium must enter the synaptic end bulb to stimulate the release of acetylcholine, which binds to ligand gates so sodium ions can enter the muscle fiber.
Explanation:
Skeletal fiber contractions are based on different physiological and biochemical phenomena that happen in every cell. These phenomena are due to stimulation produced by somatic motor neurons, which axons get in contact with muscle fibers through a neuromuscular synapse. In rest, attraction strengths between myosin and actin filaments are inhibited by the tropomyosin. When an action potential is originated in the central nervous system, it travels to the somatic motor neuron membrane: the muscle fiber, and activates the calcium channels releasing it in the neuron. Calcium makes vesicles to fuse with the membrane and release the neurotransmitter named acetylcholine (Ach) into the synaptic space in the juncture. Then, Ach binds to its receptors on the skeletal muscle fiber. This causes the ion channels to open, and positively charged sodium ions cross the membrane to get into the muscle fiber (sarcoplasm) and potassium get out. The difference in charges caused by the migration of sodium and potassium makes the muscle fiber membrane to become more positively charged (depolarized). The action potential caused by this depolarization enters the t-tubules depolarizing the inner portion of the muscle fiber. This activates calcium channels in the T tubules membrane, that make the calcium be released into the sarcolemma. At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to the troponin C, the troponin T alters the tropomyosin by moving it and then unblocks the binding sites. Myosin binds to the uncovered actin-binding sites, and while doing it ATP is transformed into ADP and inorganic phosphate. Z-bands are then pulled toward each other, thus shortening the sarcomere and the I-band, and producing muscle fiber contraction.
Jack has just returned from the hospital where Jack's father is recovering from a heart attack. The doctors told Jack that his dad's atherosclerosis is very serious. Jack and his wife, Melanie, are worried about Jack's father and also are starting to think about Jack's risk of also having heart disease in his lifetime. He sets up an appointment at his doctor's office and has his blood lipid levels evaluated for the first time. Let's see if you can answer some of the questions that Jack and Melanie have. Which risk factor does Jack have no control over?a. Obesityb. Geneticsc. Stressd. Atherogenic diete. Jack can change all of these risk factors.
The correct answer is B. Genetics
Explanation:
In health, a risk factor is a variable that can make a patient more likely to develop a disease or condition. Additionally, some of these factors can be controlled or changed by the patient, while others cannot be modified. Factors that can be controlled include stress, diet, weight, alcohol intake, and habits. This does not apply to factors such as age or genetics, for example, in the case of genetics, this is determined by the genes of each parent when a human being is formed, and therefore there is not any way to change this; although factors such as diet, stress, or smoking affect the expression of mutations in genes. Thus, the risk factor Jack has no control over is genetics.
Calculate the rate of photosynthesis (mm/hr) for Elodea if when measuring net photosynthesis, the water level moved up 7mm from the initial level in 10 min, and when measuring cellular respiration it took 15 minutes for the water level to move down 1 mm.
Answer:
With 6 we should multiply gross photosynthesis (as we were measuring gross photosynthesis for 10 min).
Explanation:
According to this question:-
Net photosynthesis- 3mm/20min- 1.5mm/10min
Cellular respiration- 1mm/15min- 0.66mm/10min
Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)
Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr
As we gage the photosynthesis rate in hr.
The process of photosynthesis is commonly written as 6CO2 + 6H2O → C6H12O6 + 6O2.
With 6 we should always multiply gross photosynthesis (as we were measuring gross photosynthesis for 10 min).
This means that the reactants, six CO2 molecules, and 6 water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and 6 oxygen molecules, the products.
According to this question:-
Net photosynthesis- 3mm/20min- 1.5mm/10min Cellular respiration- 1mm/15min- 0.66mm/10min
Gross photosynthesis = Net photosynthesis + respiration = 1.5+0.66 = 2.16 (mm/10min)
Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr
As we gauge the photosynthesis rate in hr.
Therefore, the correct calculation of photosynthesis is 6=2.16=12.96mm/hr.
