Which os these statements best sums up evolution?
a) rapid change in species’ habits and features
b) punctuated change in a population
c) change in a population through new species being made
d) change in a population through genetic variation over time

The correct answer is D

The process of evolution presents a change in population genetics over periods of time. Therefore, it's important to remember that we can only observe the evolution by looking at the level of the population, not on the level of an individual organism.

Evolution works trough 4 evolutionary mechanisms that change the frequency of an allele in a population, leading to evolutionary change of that population and later even species. These mechanisms are : mutations, genetic drift, gene flow and natural selection.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d

the wetland preservation movement began in the u.s. in earnest with the clean water act (cwa) of 1972. although not specifically written to protect wetlands, the cwa is comprised of a series of regulations designed to prevent pollutants from contaminating u.s. waters.
