Answer:
A. Molecular changes such as extracellular signals on extracellular ligands can result in quick changes in cell behaviour. One example is insulin. Upon insulin binding on the receptor on the cell membrane, the cell release GLUT4 transporters (for muscle cells) to increase uptake of glucose.
B. Slow changes in cell behaviour can be observed for other lipophilic hormones or intracellular receptors such as glucocoortoid or estrogen which reacts with receptors in the cells.
C. Insulin is required to maintain a constant blood glucose level and hence levels of insulin has to be mediated in correspondence to the blood glucose levels. Fast acting signalling is thus required for homeostasis of blood glucose levels. Where for such lipophilic hormones such as steriods, glucocortoid, these hormones tend to have a longer lasting effect and hence results in a slow change.
Answer:
Hypothalamus is considered as the one to control the Sleep-Wake Cycle, injury to that region will likely cause deprived sleep and mostly an awkward behavior.
Explanation:
A postzygotic barrier is the sort of reproductive barrier that prevents the hybrids from reproducing after a lion and a tiger mate and create offspring.
<h3>What does the biological term replicate mean?</h3>
Reproduction is the process of producing descendants. The two basic types of reproduction are sexual and asexual. A sexually reproducing organism is genetically different and has the genetic information of both of its mothers. Genetically identical children are produced through asexual reproduction by having each parent repeat itself.
<h3>What is the name of the reproductive process?</h3>
Reproduction is the process by which new individual creatures, or "offspring," are produced from the "parent" or "parents" (or procreation or breeding). Reproduction is a fundamental element of all known life, and it is the reason that every single organism exists.
