FAQs

Are selective pressures on the east lava flow population are not strong enough to maintain Hardy Weinberg equilibrium? ›

The selective pressures on the East lava flow population are not strong enough to maintain Hardy - Weinberg equilibrium. The East lava flow population does not experience migration, which is a required condition for Hardy - Weinberg equilibrium.

Answer. An alternative hypothesis Fox could have used is: Simple proteins can form spontaneously from amino acids under conditions simulating early Earth environments.

The mice that have fur colors matching the colors of their environment will have a better chance of survival. These are Mouse A (light-colored fur in a light-colored environment) and Mouse B (dark-colored fur in a dark-colored environment).

The AP Bio multiple-choice section can be quite challenging, but with the right approach, it's definitely manageable. Here are some tips and strategies that many students have found helpful: 1. Read the questions carefully: As you practice, make sure to read each question and its associated answer choices carefully.

What is a good AP® Biology score? Receiving a 3, 4, or 5 is generally accepted as scoring well on an AP® exam. According to the College Board a 3 is 'qualified,' a 4 'well qualified,' and a 5 'extremely well qualified.

Answer and Explanation:

Hardy and Weinberg wanted to answer the question; how do allele and genotype frequencies change over generations?

The Hardy-Weinberg model states that a population will remain at genetic equilibrium as long as five conditions are met: (1) No change in the DNA sequence, (2) No migration, (3) A very large population size, (4) Random mating, and (5) No natural selection.

So, the correct answer is 'Individuals with the most favorable traits survive and reproduce'

Evidence for evolution: Molecular biology

Like structural hom*ologies, similarities between biological molecules can reflect shared evolutionary ancestry. At the most basic level, all living organisms share: The same genetic material (DNA) The same, or highly similar, genetic codes.

Which hypothesis about modern humans is best supported by experimental evidence? ›

Most genetic evidence supports the Out of Africa hypothesis, or a close variant of it. Nearly all genetic studies indicate greater diversity in African populations (Figure 1), which is consistent with an African origin of modern humans.

Stabilizing selection results in a decrease of a population 's genetic variance when natural selection favors an average phenotype and selects against extreme variations.

A heritable trait that increases fitness is called an adaptive heritable trait. Individuals with an adaptive heritable trait generally produce more offspring than individuals that do not have this trait.

Justify your answer in one or two sentences: “The same mutation could be advantageous in some environments but deleterious in others.” True; the environment or selective pressure determines whether a mutation is beneficial.

Determine your own answer before examining the choices OR—more typically—use process of elimination (and cross out the choices you know are wrong). Focus on the question's wording. Read all the choices. Don't select the first right answer when a later option is better.

Scoring a 5 is the absolute best score. However, scoring between 3 to 5 may also qualify you for placement and free credits in college.
