Black-bellied seedcrackers have either small beaks (better for eating soft seeds) or large beaks (better for hard seeds). There

are no seeds of intermediate hardness; therefore, which kind of selection acts on beak size in seedcrackers

Answer:

disruptive selection

Explanation:

disruptive selection causes both extreme phenotypes to be favored over the intermediate phenotypes.

Answer:

The answer is Disruptive Selection.

Explanation:

The Disruptive Selection is defined as "the situation where the selection trait is against the individual in the middle of the trait spectrum.". In the given example, there are no suitable seeds for the seedcrackers with medium sized beaks. So the criteria for the selection which is the beak size in black-bellied seedcrackers is on the different ends of the spectrum. The beaks are either small, or large. Which means that the selection trait affects the seedcrackers in the middle of the trait distribution. Therefore the answer is Disruptive Selection.

Based on biology and neo-Darwinism, _____ explains how environment selects organizations for survival or extinction.
lutik1710 [3]

Given what we know, we can say that biology and neo-Darwinism both support the idea that natural selection explains how the environment selects organizations for survival or extinction.

<h3>Natural Selection. </h3>
  • This concept is often summarized by the phrase "survival of the fittest".
  • This refers to the ability of an organism to adapt to its environment.
  • The better-adapted organisms will live to pass on their genetic information, thus changing the organization of the species.
  • Those not able to do so will face extinction.

Therefore, since natural selection involves the survival or extinction of a species based solely upon their ability to adapt and change their genetic organization in response to their environment, we can say that this concept helps to explain how the environment selects organizations for survival or extinction.
