Answer:

I'm not sure if this is right, but i believe the right answer would be fracture.

Explanation:

In geology, a fracture is any separation in a geologic formation, such as a joint or a fault that divides the rock into two or more pieces. A fracture will sometimes form a deep fissure or crevice in the rock. Fractures are commonly caused by stress exceeding the rock strength, causing the rock to lose cohesion along its weakest plane.

hope this helps :)

Answer:

Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.

Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).

Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).

Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.

Introduction

We've already met a few different mechanisms of evolution. Genetic drift, migration, mutation...the list goes on. All of these mechanisms can make a population evolve, or change in its genetic makeup over generations.

But there's one mechanism of evolution that's a bit more famous than the others, and that's natural selection. What makes natural selection so special? Out of all the mechanisms of evolution, it's the only one that can consistently make populations adapted, or better-suited for their environment, over time.

You may have already seen natural selection as part of Darwin’s theory of evolution. In this article, we will dive deeper – in fact, deeper than Darwin himself could go. We will examine natural selection at the level of population genetics, in terms of allele, genotype, and phenotype frequencies.

Quick review of natural selection

Here is a quick reminder of how a population evolves by natural selection:

Organisms with heritable (genetically determined) features that help them survive and reproduce in a particular environment tend to leave more offspring than their peers.

If this continues over generations, the heritable features that aid survival and reproduction will become more and more common in the population.

The population will not only evolve (change in its genetic makeup and inherited traits), but will evolve in such a way that it becomes adapted, or better-suited, to its environment.

erastovalidia [21]

Answer:

DDT was once considered a "silver bullet" that would permanently eradicate insect pests. Instead, DDT is largely useless against many insects. Which of these would have prevented this evolution of DDT resistance in insect pests?

What would have prevented the evolution of DDT resistance in insect pests is the None of the insect pests would have genetic variations that resulted in DDT resistance.
