It is the
A. DNA molecules need to unwind before replication being
Two species of sea urchins live practically side-by-side in sandy bottoms. The two species appear to have the same diet: drift seaweeds and other bits of organic matter. They can live in the same environment without competing.
As it compels them to live in the same environmental surroundings so the characteristics of living nature also get developed as their current following situation that's helping them to get the same food & habitat.
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).
The right answer is: <span>A
<span>A biogeochemical cycle is the process of transport and cyclic transformation of a chemical element (like oxygen, carbon or azote) or a compound between the large reservoirs that are the geosphere, the atmosphere, the hydrosphere, in which the biosphere is found.
</span>The three elements are able to exist in a gaseous form in the atmosphere to complete their respective natural cycle.</span>
<span> The organism is better able to survive and pass on traits to offspring than competing organisms.
For example;
A population of orange and green beetles. A bird likes the green beetles much better, thus they eat the green beetles. The surviving beetles (orange beetles) pass on their trait to their offspring.</span>
