It is called the control experiment
Answer:
a) Some island populations will have fixed one allele, and other populations will have fixed the other allele.
Explanation:
The founder population for each island is heterozygous for the locus. The absence of any migration and mutation would result in no gene flow or the introduction of new alleles of the locus. Over several generations, one or the other allele will be fixed in the populations depending on the adaptive features imparted by each under the different conditions present on these different islands. Genetic drift may also work on these small founder populations to randomly fix one or the other allele.
Nocturia, or nocturnal polyuria, is a medical term which means excessive urination at night. The two primary causes of nocturia are hormone imbalance and vesicle problems. Arginine vasopressin (AVP) and atrial natriuretic hormone (ANH) are two of the hormones that controls the body water level. AVP is an antidiuretic hormone produced by hypothalamus while ANH is released by cardiac muscle cells in response to high blood pressure. Arginine vasopressin (AVP) is an antidiuretic hormone which increases water absorption in the collecting duct systems of of kidney nephrons subsequently decreasing urine production. In the abovementioned question, nocturia is caused by decreased production of antidiuretic hormone, which is the arginine vasopressin. Nocturia, moreover, is can be caused by congestive heart disease, nephritic syndrome or liver failure. Excessive nighttime drinking and obstructive apnea can also lead to nocturia
The temperate coniferous forest contains tress which have adapted to have very thick bar, like evergreen trees. I might be wrong, but that is what I think.
