Answer:
Nuclear Fusion
Explanation:
The Sun gets its energy from the process of nuclear fusion. This process occurs in the sun's core or interior
Answer:
Changes in allele frequencies over time can indicate that genetic drift is occurring or that new mutations have been introduced into the population.
Enzymes are affected by changes in pH. The most favorable pH value - the point where the enzyme is most active - is known as the optimum pH
Answer:
1) B) insulin
2) A) glucagon
3) C) epinephrine
4) B) insulin
5) A) glucagon
6) A) glucagon
Explanation:
High levels of glucose in the blood promote the release of insulin hormone which functions to stimulate uptake and utilization of glucose by cells. Insulin may also act to inhibit lipolysis in adipocytes and stimulates triglyceride storage. Glucagon hormone controls blood sugar (glucose) by stimulating glycogenolysis (conversion of glycogen to glucose), promoting gluconeogenesis (glucose synthesis), and inhibiting glycolysis (glucose breakdown). Moreover, glucagon also can increase ketogenesis (i.e., the production of ketone bodies by breakdown of fatty acids and ketogenic amino acids) when insulin is inhibited. Finally, epinephrine hormone binds to receptors localized on the surface of muscle cells, which stimulate the production of cyclic-AMP (cAMP), a second messenger (i.e., a signaling molecule).
