A. Increase in biodiversity
B. Increased access to useful minerals
C. Increased loss of soil nutrients
D. Increased recharge of groundwater
Answer:
C. Increased loss of soil nutrients
Explanation:
Deforestation and land degradation are the processes that adversely affect the environment. The continued process in the image can lead to the loss of soil nutrients. Thus, option C is correct.
What is deforestation?Deforestation is the process of destroying a large mass of the area by cutting and excluding the trees for various purposes including the building of infrastructure, roads, mining, etc.
Deforestation and land degradation are the factors that have a negative impact on the environment as ity leads to an increased level of pollution and destroys the soil quality and disturbs the water table.
The tree roots are involved in holding the soil that can get carried away by the strong winds and water. Deforestation can lead to soil erosion and a decrease in soil nutrients.
Therefore, the process of land degradation and deforestation can lead to increased loss of soil nutrients.

Being nervous interferes with sexual arousal. Explain why, with reference to the sympathetic and parasympathetic nervous systems.
Answer:
When one is nervous activates the sympathetic system and the irrigation towards the cardiac and muscular zone is increased, increases the arterial tension and the respiratory rate.
That is why the blood or blood volume is dispersed in these organs to be able to render efficiently in a moment of stress or flight for the human.
When we have sexual intercourse and there is sexual excitement, a large part of the blood volume goes to the reproductive organs to be able to irrigate the area and produce said excitement, if we are stressed in an alert situation, it will be harmed by the priority body to irrigate the main areas like heart and muscle.
Explanation:
It is important to clarify that the physiological stress in humans is a normal situation, thanks to the presence of cortisol and it is what keeps us active, but if it increases due to anxiety or overwork, psychological problems, etc., it will no longer be physiological due to that is in excess.
Thus, sexual arousal will also be affected by the psychological impotence generated by excess mental stress outside the vascular pattern.

How could you use different research methods to complement each other when studying a particular process in the brain?
Answer is given below
Explanation:
The brain is a complex structure and requires different methods to be declared in order to obtain a clear illustrator. Cavalder study is a method of comparing the brain of a dead person. For example, Einstein compared the brain to the brain of ordinary people. It has been hypothesized that the proportion of glia cells in the neuron is higher in a person with a higher IQ, such as Einstein. However, it cannot be confirmed that only a specific brain is available. The study of the session helps us to identify the problem associated with defects in a particular area and eliminates the function of a specific area of the brain. For example, clots form in the frontal lobe during a stroke, which can sometimes lead to epilepsy. The disadvantage of these methods is that the brain is not active. A new method of EEG electroencephalogram that measures electrical signals if each neuron is present. It measures brain activity when the brain is active. The EEG can provide information about the normal patterns of electrical activity in the brain, and although the EEG allows the researcher to quickly observe when these changes occur in real time, the electrode measures the surface of the skull and each electrode measures brain waves from large areas to be placed on the brain. EEGs do not provide a very clear picture of brain structure. The image of the brain cannot be obtained by changing the electrode to measure the electrical signal. but there are MRI techniques to provide more specific brain images. Functional magnetic resonance imaging uses the scan method using magnetic fields to create an image of the brain in each activity field. Therefore all mixed methods can help to study the brain and related activities more deeply and effectively.Answer:
Brain is a complex structure and needs analgamation of various methods to get a clearer picture.
One method is cavalder studies where brains of dead person is compared. For instance , Einstien brain was compared with ordinary people brain. The ratio of glia cells to neuron was hypothesised to be higher in high IQ person such as Einstien. However , this cannot be ascertained as only one special brain was available.
Lession studies help us identify the problem associated with a lession in a particular area and conclude the function of specific region of brain.for example , during stroke the is clot in frontal lobe that leads to epileptic ceasure sometimes.
Drawback of these method is that brain is not active. So new method of EEG electro encephelogram which measure electrical signals if each neuron. It measures brain activity when brain is active.
the EEG can provide information about the general patterns of electrical activity within the brain, and although the EEG allows the researcher to see these changes quickly as they occur in real time, the electrodes must be placed on the surface of the skull and each electrode measures brain waves from large areas of the brain. As a result, EEGs do not provide a very clear picture of the structure of the brain. A still images of brain cannot be obtained by placing electrodes to measure electrical signal.
But MRI techniques exist to provide more specific brain images. Functional magnetic resonance imaging uses a scan method utilising magnetic field to create an image of brain in each activity area.
Thus all methods combined can help in study of brain and associated activities more profoundly and effectively.

Answer:
carbohydrates
Explanation:
Answer:
Carbohydrates
Explanation:
Carbohydrates are compounds made primarily of carbon, hydrogen, and oxygen that store the most energy. Generally, these are known as sugars. These molecules are required for cellular respiration and ATP production. Lipids and fats store energy, but are not used in ATP production. Proteins do not store energy and instead provide the raw materials for the body to build other molecules, called amino acids.

The diagram shows the position of earth during solstice. select the area that would be getting around 24 hours of daylight each day.
The answer is Artic Circle Zone (red square at the top)
Explanation:
A solstice occurs two times in a year when the Sun reaches farther either the south or the north of Earth. In the image presented, there is a solstice because the sunlight reachers farther in the North. Additionally, this phenomenon occurs due to the tilt (inclination) of Earth, and it increases the number of daylight/night hours in different zones.
In the case of the Arctic Circle Zone (north pole) it is likely during the solstice, this zone has around 24 of daylight each day because almost all this zone is directly exposed to the sunlight, and therefore this will always be reached by sunrays despite the rotation of Earth (rotation of Earth in its axis). On the other hand, other zones will not be exposed to sunlight all the time because the location and rotation will cause these areas are in the dark zone of Earth during specific hours every day.
Answer: The top red square near the axis.
Explanation:
Ok, the Earth's axis is the "line" around which the Earth rotates.
This means that after a rotation, the 3 bottom red boxes will be in the dark side of the diagram ( for example, if you have a ball and you grab it with the logo facing you, when you rotate the ball, the logo will be in the other side, and you will not be able to see the logo).
Now, as the area near the axis actually does not move that much, the red square near the axis (the top red square) will be most likely getting 24 hours of light each day.

ASAP You are observing proteins in a lab for an experiment. During transport, they have started to unwind and lose their shape. You notice long strands wound into alpha helices. What level of structure are the proteins in? A. Quaternary B. Primary C. Secondary D. Tertiary
Answer:
C. Secondary
Explanation:
In proteins, the structure of local segments can be arranged into three different three-dimensional formations: alpha helices (α-helix), beta sheets (β-strand) and omega loops. An alpha helix is the most common secondary protein conformation because it has low-energy and a stable arrangement. The α-helix is formed by the interaction between amino acids of every backbone N−H hydrogen bonded with the backbone C=O group of the corresponding amino acid residue in the polypeptide chain. The α-helix motif is very common in transmembrane segments of proteins that cross the lipid bilayer.

Summarize the differences between how the salt-sensitive plant cell and the salt-resistant plant cell behave in the 10% salt solution..
Answer:
Salt sensitive plants when exposed to a 10% salt solution will result in the water in the plant cell to leave and get attached to the salt solution through the process called Osmosis. Osmosis is a phenomenon which occurs as a result of movement of fluid from a region of lower concentration to a higher concentration.
This causes the plant cells to shrink and wilt.
However when a salt-resistant plant is exposed to a 10% salt solution osmosis doesn’t occur and the plants remains the same without any form of shrinkage or wilting.
A plant that is sensitive to salt means that when it is placed in a salt solution it's cell structure will change by the process of osmosis.
Osmosis is the movement of water molecules through a semi permeable membrane from a region of low solute concentration to a region of higher solute concentration.
Therefore when the salt sensitive plant is placed on the 10% salt solution, there would be water loss from the intercellular compartment to the extracellular leading to the protoplasmic shrinking called plasmolysis.
A plant that is resistant to salt means that the plant is not in anyway affected when placed in a salt solution.

D.H., a 54-year-old resort owner, has had multiple chronic medical problems, including type 2 diabetes mellitus (DM) for 25 years, which has progressed to insulin-dependent DM for the past 10 years; a kidney transplant 5 years ago with no signs of rejection at last biopsy; hypertension (HTN); and remote peptic ulcer disease (PUD). His medications include insulin, immunosuppressive agents, and two antihypertensive drugs. He visited his local physician with complaints of left ear, mastoid, and sinus pain. He was diagnosed with sinusitis and Candida albicans infection (thrush); cephalexin (Keflex) and nystatin were prescribed. Later that evening he developed nausea, hematemesis, and weakness and was taken to the emergency department. He was admitted and started on IV antibiotics, but his condition worsened throughout the night; his dyspnea increased and he developed difficulty speaking. He was flown to your tertiary referral center and was intubated en route. On arrival, D.H. had decreased level of consciousness (LOC) with periods of total unresponsiveness, weakness, and cranial nerve deficits. His diagnosis is meningitis complicated by an aspiration pneumonia and atrial fibrillation. D.H. has continued fever and leukocytosis despite aggressive antibiotic therapy.
What is the probable route of entry of bacteria into D.H.'s brain?
Answer:
Chances are, you haven't infected the bacteria in a hospital setting or surgery, as you could have contacted them anywhere.
What happened with said patient was the face of the immunosuppressive treatment, the defense of the patient was decreased and it generated a worse picture with a bacterium that would not act in such a pathogenic way in another person who does not receive corticosteroid treatment.
This deduction could be made since prior to pneumonia and meningitis there were other infections that occurred in the patient indicating immunosuppression or lowered immunity, which were alerts for professionals.
Explanation:
The immunosuppression generated by corticosteroids is an adverse effect of said drug, thus causing bacteria or other pathogenic microorganisms to more easily generate lethal diseases that occur, similar to the human immuno-insufficiency syndrome.
These pneumonias and meningitis are very common in children but not in adults, which means that the defense of acquired immunity throughout life would not be serious.
In patients like these where corticosteroids suppress the path of humoral defense factors, thus inhibiting the presence of COX and thromboxane A2 in the immune lineage, that is why the immunological tests are weakened and the bacteria have more spread or harmful effects such as this patient.
The bacterium does not indicate that it is intra-surgical or hospital-based because of the severity of the disease it triggered, but because the patient is immunosuppressed.
A part of an mRNA has the sequence GGA. Which change to the sequence would indicate a missense mutation
Answer:
A replacement of a letter with different letter would indicate a missense mutation. (eg. GGA would become something like GCA and it would make something completely different).
Explanation:
A missense mutation is when the RNA replicates the instructions wrong from the DNA. When RNA is transcribed to make amino acids, it will make a completely different amino acid rather than the one that is needed/blueprinted. For example, if the sequence was AAG in the RNA (Derived from TTC DNA), it would create Lys amino acid. However, if the RNA sequence was AGG (Derived from abnormal TCC DNA), it would make Arg amino acid, which is different.

O A. One long, three short
B. Four long, zero short
O C. Two long, two short
O D. Three long, one short
PREVIOUS
Answer:
The punnet square in this question is unclear. The punnet square has been attached as an image.
Based on the punnet square, the answer is C. Two long, two short
Explanation:
This question involves a single gene coding for needle length in cactus plant. The allele for long needle (L) is dominant over the allele for short needle (l).
According to the question, two cacti were crossed with genotypes Ll and ll respectively. The following allelic combinations of gametes will be produced by each parent
Ll- L and l
ll- l and l
Using these gametes in a punnet square (as seen in the image below), four possible offsprings with genotypes: Ll and ll will be produced in a 1:1 proportion.
Ll offsprings will be phenotypically long-needled while ll offsprings will be phenotypically short-needled. Hence, two long needle offsprings and two short needle offsprings will be produced in this cross.

Why are scientists studying the effects of warming on boreal forests? How far might this forest biome move if climate projections are correct?
Answer:
Scientists studying the effects of warming on boreal forests which change the biome.
Explanation:
The main effect of warming on boreal forests is to change the biome because the plants and animals will not tolerate the increased temperature which occcurs due to climate change so the plants and animals disappeared from the boreal forests and change its biome. The animals migrated to other suitable environment where they continue its growth and increase their population. If climate projections are correct, the biome of this forest go to those places where the environment is suitable.
