Question

When environmental change occurs, variation allows for individuals with characteristics that are most beneficial to survive and reproduce at higher rates than those that are less well-adapted.

a. True
b. False

Answer 1

False

Step-by-step explanation:

Traits that are not heritable will be lost with time, heritability of a traits lead to its continuity.

Heritability is the proportion of variation that is heritable.

If a traits is not inherited or passed to the successive generation the ability of such traits to continue is low and with time such traits is loss.

An organism may reproduce well, have characteristics that are important it does not lead to survival heritable traits controlled by major genes is what leads to survival of traits and its availability.

Answer 2

a. True

Explanation:

According to the evolutionary theory proposed by Darwin, adaptation is the process by which organisms adjust to new environments in order to survive and reproduce. An organism that is better able to adjust to the changing environment will have more chances to survive and reproduce in order to pass its genes to the next generation. The differential survival and reproduction of organisms in a population caused by differences in the phenotype is known as "natural selection", which is the most common mechanism of evolution.
