Savannas are under threat all over the world because to human activity such as logging, construction, agricultural conversion, animal overgrazing, and introduction of non-native plant species. For instance, overgrazing by goats and cattle has mostly eliminated the vegetation that holds the soil in place in the drier regions of the African savanna.

B. Decreased renal functioning. Prior to aerobic activity, consuming substantial amounts of bicarbonate has little effect other than on the kidneys' ability to operate.

Through the ERK1/2 pathway, quercetin increases insulin production & protects INS-1 pancreatic β against oxidative damage. The left ventricle of the heart is the area that adjusts the fastest to repeated endurance exercise. Chronic endurance exercise causes the left ventricle's myocardial wall thickness to thicken, its contraction force to rise, and the size of the ventricle's chamber to expand. Prior to aerobic activity, consuming substantial amounts of bicarbonate has little effect other than on the kidneys' ability to operate.The greatest method to translate the advantages of acclimatization into enhanced aerobic performance is to live and exercise at altitude.

Explanation:

The pathway that would be inhabited by avidin is lactate. Therefore, the correct answer is option A.

Biotin is the cofactor that's involved in the conversion of pyruvate to oxaloacetate with the help of the enzyme pyruvate carboxylase.

Lactate is formed when the rate of glycolysis is higher than the rate of oxidation. When that happens, the lactate is converted to form pyruvate with the help of the enzyme lactate dehydrogenase.

  Lactate + NAD+ -----> pyruvate + NADH + H+

The pyruvate is then converted to form oxaloacetate in the presence of biotin.

  Pyruvate + CO₂ + ATP + H₂O ----> Oxaloacetate + ADP + Pi + 2H+

Avidin binds tightly to the biotin. Thus avidin can inhibit the biosynthesis of glucose from lactate and its pathway.

Fibroblasts also produce and secrete factors that attract other cells of the immune system, such as macrophages and lymphocytes, to the site of injury or infection. This is the basis of the inflammatory response.

Fibroblasts are also important for wound healing, tissue repair and remodeling, and for the regulation of tissue homeostasis.

Bandura believes that self-reinforcement and self-punishment are effective for people who are more likely to feel guilty for going against the standards they set for themselves.

Self-reinforcement and self-punishment are two strategies for managing and controlling our behavior. Self-reinforcement is the process of rewarding oneself for engaging in desired behaviors. This can include rewarding yourself with a special treat for a job well done, or it could be as simple as feeling a sense of pride or accomplishment for completing a task. Self-punishment, on the other hand, is the process of punishing oneself for engaging in undesired behaviors. This can be done by denying oneself a reward or pleasure, or by actually inflicting physical or psychological pain in response to one’s own behavior.

The correct answer is d. I and II.

Autonomic motor neurons regulate visceral activity by increasing and decreasing the activity of effector tissues.

Autonomic neurons are a type of nerve cell that regulates the activity of the body's involuntary or "visceral" muscles and organs. The Autonomic Nervous System “ANS” is the part of the nervous system that controls these involuntary functions.

The sympathetic nervous system is responsible for activating the body's "fight or flight" response during times of stress or danger. It does this by releasing the hormone adrenaline and increasing heart rate, blood pressure and breathing.

The sympathetic nervous system also stimulates the production of glucose by the liver and the breakdown of fat in adipose tissue, providing the body with energy during periods of high activity.

The parasympathetic nervous system, on the other hand, acts to balance the sympathetic nervous system, promoting relaxation and calmness. It does this by slowing the heart rate, lowering blood pressure, and increasing the digestion and absorption of nutrients.

Autonomic nerve cells are activated by signals from the brain and spinal cord and can also be influenced by hormones and other chemicals in the body. They use chemical signals called neurotransmitters to communicate with the muscles they control and communicate with organs.

For example, if one parent is heterozygous for a gene that determines eye color and has one dominant allele for brown eyes and one recessive allele for blue eyes, and the other parent is also heterozygous for the same gene with one dominant allele for brown eyes and one recessive allele for blue eyes, then each parent has a 50% chance of contributing either the dominant or recessive allele to their offspring.

Blood is carried away from the heart through arteries. Blood is returned to the heart through veins. Body cells and tissues are surrounded by capillaries.

Arteries transport blood away from the heart. Veins allow blood to return to the heart. Capillaries that carry and absorb nutrients, oxygen, and other molecules surround body cells and tissues.

The tunica externa, tunica media, and tunica intima are the three different layers that make up the walls of the majority of blood arteries. The lumen, the hollow interior through which blood flows, is encircled by these layers.

Blood is sent back toward the veins by capillaries after it has been used by bodily tissues to absorb oxygen and other components from the blood. The blood first enters venules, which are tiny branches of vein. Blood is carried via the venules into the veins, which then carry it back to the heart via the venae cavae.
