Answer:A
Explanation:
Answer and Explanation:
The correct matching would be
(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)

3)Atoms and molecules are added to dust grain, masses of matter form around dust grain, and masses of matter collide.
4)Masses of matter collide, atoms and molecules are added to dust grain, and masses of matter form around dust grain.
Answer:
The correct option is 3. Atoms and molecules are added to dust grain, masses of matter form around dust grain, and masses of matter collide.
Explanation:
Two theories explain how planets get formed. One of them is The gravitational instability, and the other one is the Planetesimal Hypothesis.
The planetesimal hypothesis says that a planet formation is a process in which dust particles and gas collide and get stick together in a process known as coagulation. This makes place to grains production. These grains enhance their sizes up to a point in which they form bodies big enough to be called planetesimals. When planetesimals are formed, they start a gravitative interaction with other planetesimals of different sizes, and by collision, they form bigger planetesimals that accrete the smaller ones and end up forming a proto-planet. Planets and giant planets get formed by accretion of solid planetesimals. The term accretion refers to the solids agglomeration to form bigger objects, such as planets.

4. provides structural support
6. increases vascular flow
7. growth in thickness
10. lateral meristem
11. vascular cambium
Both:
8. occurs in plants that live many years
Explanation:
Plant primary growth starts with successive cell division cycles in undifferentiated cells that form the shoot apical meristem, thereby lengthening roots and stems. The meristems represent a type of tissue involved both in primary and secondary growth. Herbaceous plants have only primary growth and grow in length.
Secondary growth is caused by the growth of the vascular cambium (cambia) and lateral meristems. It is characterized by an increase in thickness of stems and roots. Vascular plants (i.e., plants with a xylem and phloem system) have secondary growth.
In woody plants, the primary and the secondary growth patterns occur across years, and thus they can increase their length (primary tissue growth) and diameter (secondary tissue growth).

Cam plants mean crassulacean metabolic pathway.
This plant undergoes photosynthesis by seperation in time in other to reduce photorespiration.
Cam plants opens their stomata at nights, absorb Carbondioxide and store as oxaloacetate with the help of phosphoenol pyruvate carboxylase an enzyme that helps ferry co2 into the cell, oxaloacetate is then converted into malate and other organic acid and then stored in the vacoule. In the day the stomata closes and the stored malate is released from vacoule are broken down into pyruvate and CO2 in the mesophyll cell. The CO2 is then used in the calvin cycle to produce the G3P while pyruvate goes back to the cycle.

"Assume that a man and a woman are phenotypically normal, but the woman is heterozygous for a pericentric inversion on chromosome 8. The man is karyotypically normal. What is the probability that this couple's child will inherit a duplicated or deficient chromosome 8 that results from crossing over within this pericentric inversion
Answer:
Explanation:
Pericentric inversion results in chromosome have extra copies of some genes while some genes do not have copies. It can result in slow growth rate.
If a man is heterozygous of pericentric and a woman is heterozygous of pericentric although they do not show symptoms there is 25% chance that their offspring will have it and 50% chance of them being a carrier.
T t × T t will give TT T t T t t t

NASA’s Kepler mission found evidence of several potentially habitable exoplanets, raising the possibility that life may have evolved independently outside of our solar system. If NASA found a novel lifeform, we would expect it to use energy molecules based on similar principles as lifeforms on Earth. The organism would likely use molecules with _____________ bonds. It might use two separate molecules, one serving as a rapidly utilizable energy currency and another molecule serving as long-term energy storage
Answer:
The organism would likely use molecules with Covalent bonds.
Explanation:
A covalent bond is a chemical bond that is prevalent in most matter and facilitates the sharing of electron pairs between atoms. Molecular Bond is another word for a covalent bond.
Molecular bonds are a repository of potential energy. This type of energy is also referred to as Chemical Energy.
Covalent bonds may take the form of single, double, and triple bonds. In order to separate any pair of bonded atoms, energy is required. The more strong a covalent bond is, the higher the amount of energy that is required to break it.

Assume that the import of a particular amino acid across the plasma membrane is observed (1) to occur only down its concentration gradient and (2) to slow when a different but similar amino acid is added to the extracellular fluid. The movement of the amino acid through the membrane is most likely by
Answer:
The correct answer is - facilitated diffusion.
Explanation:
Facilitated diffusion is a form of facilitated transport of molecules such as amino acid, glucose, and others through the plasma membrane involving the passive or indirect movement of molecules along their concentration gradient, which is led by the presence of another molecule normally a pore or channel made up of integral protein.
Facilitated diffusion depends on several factors such as the size of molecules, type of molecules, similarity of molecules to extracellular matrix or fluid that slow or fast the diffusion process.
Thus, the correct answer is - facilitated diffusion.
In an accident with farm machinery, Mr. Roque had his left arm severed just below the elbow. Mrs. Roque stopped the bleeding, called for an ambulance, and packed the severed arm in ice for the EMTs to take to the hospital. Will Mr. Roque ever be able to move the fingers of his left hand again? What structures must be reattached, and what has to happen?
Answer:
The mentioned case of arm severing is considered as major surgery, and the restructuring of the severed arm is only possible when Mr. Roque will reach the hospital within four to five hours of the incident, also known as the window period.
After performing the surgery, Mr. Roque may regain movement in the arm to some extent after performing certain kinds of exercises, however, he may not feel the sensations in the fingers of his left hand again. The entire process of healing of the severity may take about two to three years, and in certain cases, the body fails to heal completely, and the affected limb may lose its function entirely.
In the given case, the structures that are required to get reattached are the muscles of the forearm and the blood vessels and the nerve supply to the affected region. The systematic arrangement of these structures is done with the help of surgery. However, after the surgery, the patient is recommended to perform certain kinds of hand and finger muscle exercises so that the functioning of the arm get regain slowly and gradually.

What are one benefit and one consequence of building a desalination plant? Would a desalination plant be beneficial to your local area? Explain why or why not.
Answer:
Desalination plants, also known as desalination plants, are industrial facilities for desalination, generally of the sea or salty lakes, to obtain drinking water.
Explanation:
The benefits are clear: having clean water in places where it is scarce. But, on the disadvantages side, it is a process that requires a lot of energy and is therefore expensive. In addition, desalination plants have an impact on marine ecosystems that must be assessed, they increase the temperature of sea water and reduce the amount of oxygen in the water, causing serious damage to aquatic life.
Answer:
a. Dams help make irrigation possible so that farming can occur in dry regions .
Explanation:
Certain natural compounds and drugs being tested as treatments for diabetes lower glucose transport in intestinal or kidney epithelial cells, and thereby lower blood sugar levels. Addition of one such drug to the apical medium yields transport similar to that in Treatment 5, whereas its addition to the basolateral medium yields transport similar to that in Treatment 4. What is the most likely target of this drug, and what is the effect on this target?
Answer:
Lowering serious blood glucose concentration and avoiding glycemic spikes (target).
The consequences of this seriously that by maintaining glycemia and glycemic levels the patient does not undergo glycosidization of cellular components, the first line of immune defense is not affected, blood vessels are not affected, affected cardiac pathologies are avoided, no Coagulation, scarring, and collagen synthesis are impaired.
Explanation:
The increase in blood glucose is called glycemic peak or high blood glucose, this is what happens in diabetic patients.
These drugs at the intestinal level, generate a decrease in the speed of glucose absorption, thus avoiding glycemic spikes or high blood glucose levels, therefore maintaining constant values that are easier for the administration of insulin via parenteral or oral hypoglycemic drugs.
This similar effect is found in sweeteners such as stevia, that is why it is recommended in diabetics, the difficulty of these drugs or these chemicals is that since the absorption of glucose is more lethargic, the glucose remains more in the intestines and drags masses of water or allows aqueous diffusion processes into the lumen of the intestine, thus promoting the appearance of instestinal breakdowns such as diarrhea.
That is why you have to be vigilant with hydration in these specific cases.
Diabetics having high glucose generate: cardiac, immunological, scarring, vascular alterations, obesity risks.

The speckled chicken on the right results from a cross between a black and white chicken. Explain what type of inheritance this would be, and draw a punnett square to show how this would happen.
Answer:
- Codominance
- 100% speckled chicken
Explanation:
This gene inheritance is called codominance, where both alleles can be expressed. In these cases, heterozygote individuals instead of showing an intermediate phenotype, express both alleles. Their phenotype is an additive expression of their parents' genes.
When two individuals, homozygous for a certain trait, are crossed they produce heterozygous individuals that express both alleles equally.
A typical example of codominance is the case of speckled chicken, the product of the cross of a black individual with a white individual. Black chickens (BB) only have this gene for feather color, while white chickens (WW) only have the gene for white feathers. When they cross, their progeny will have both genes (BW), and both of them will be expressed as speckled feathers.
Cross:
Parental) BB x WW

Gametes) B B W W
Punnet square) B B

Your Turn For each of the following atoms or molecules, determine whether they will cross a plasma membrane (if following their concentration gradient) by simple diffusion or by facilitated diffusion. Then, briefly explain your reasoning. O2 (oxygen gas) crosses the plasma membrane bydiffusion, because Glucose crosses the plasma membrane by diffusion, because Water crosses the plasma membrane by diffusion, because Nat (sodium ion) crosses the plasma membrane by diffusion, because Cholesterol crosses the plasma membrane by diffusion, ーーーーーーーーーーーーー because Which of these atoms or molecules require facilitated diffusion to cross a plasma membrane, but are able to simply diffuse across a dialysis tubing membrane?
Answer:
1. Oxygen moves through the plasma membrane by simple diffusion, as oxygen will be utilized fast for cell metabolism that will result in the concentration of oxygen inside a cell will always be less
2. Although the concentration of glucose is more outside a cell it cannot cross the plasma membrane by simple diffusion and crosses the plasma membrane by facilitated diffusion as glucose is a large and more polar molecule. A carrier protein called glucose transporter helps in this movement.
3. Water crosses the plasma membrane by simple diffusion as it has a small size.
4. Na+ ions are charged ions and cannot pass the plasma membrane by simple diffusion and they are carried in with the help of sodium pumps that are made up of certain membrane proteins by facilitated diffusion.
5. Cholesterol crossed the plasma membrane by facilitated diffusion as it is a non polar molecule and is diffused through channels.

45-year-old was admitted with sarcoidosis of both lungs. An extracorporeal perfusion of donor lungs, from an unrelated donor, and successful bilateral lung transplantation were completed without any complications. What is the second code you should assign
Answer:
The second code in this case is the procedure for perfusion
Explanation:
Extracorporeal perfusion is the process of diverting the patient's blood via an artificial circulatory device to enable the gas exchange (oxygen absorbed, carbon dioxide removed) to take place. Only medical experts should handle this procedure so as to avoid any and all undesired scenarios or negligence towards patient care.
In sheep, coat color is influenced by two genes. Gene A influences pigment production, while gene B produces black or brown pigment. If two heterozygous white sheep resulted in 12 white sheep, 3 black sheep, and 1 brown sheep, which genotype(s) of the white sheep explain this data?
Answer:
Dominant epistasis best explains this ratio of 12:3:1.
Genotype(s) AABB, AABb, AAbb, AaBB, AaBb and Aabb explain white phenotype of sheep.
Explanation:
It is a clear case of dominant epistasis which is in turn a result of gene interaction. In dominant epistasis, dominant allele of one gene masks the expression of another gene which is present at different locus.
When we will cross two heterozygous sheep AaBb x AaBb, progeny with following genotypes will be produced:
1- AABB - White
2- AABb - White
1- AAbb - White
2- AaBB - White
4- AaBb - White
2- Aabb - White
1- aaBB - Black
2- aaBb - Black
1- aabb - brown
In this case, dominant 'allele A' of gene A will mask the expression of gene B. This is the reason why genotype AABB, AABb, AAbb, AaBB, AaBb and Aabb are producing white phenotype. So in total, 12 sheep will produce white phenotype.
But when dominant 'allele A' is absent, then only gene B will be able to express if it is present in dominant form. This is the reason why aaBB and aaBb are producing black phenotype because here dominant allele A is absent and recessive allele a will not be able to mask the expression of gene B because gene B has dominant allele here i.e. BB and Bb. So 3 sheep will produce black phenotype.
But when when dominant 'allele A' is absent and gene B is in recessive form i.e. bb then a third phenotype will be produced which is brown. This is the reason why aabb will produce brown color. So only 1 sheep will produce brown phenotype.
