Genetic drift always causes: a) equilibrium in genetic frequencies. b) maladaptive changes in gene frequencies. c) adaptive changes in gene frequencies. d) changes in gene frequencies that are random with respect to adaptation

The correct option is (D).Genetic drift is otherwise known as the Sewall Wright effect or allelic drift and is defined as the change in the allelic frequency of a given population that results due to random sampling .

Explanation:

Genetic drift refers to a phenomenon that is characterized by the change in the allelic frequency of a given population. It results in the disappearance of the gene variants that eventually leads to a reduction in the genetic variation. Occurrence of chance phenomena like emigration and immigration and independent selection eventually leads to genetic drift. This leads to the increment in the homozygosity as the changes in the associated allelic frequency does not move in the optimum predefined direction. The major driving forces is the genetic mutation or migration apart from random selection. The increased frequency and the fixation of rare alleles also occur due to genetic drift.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
