Birds with larger beaks were better able to utilize the large seeds.
DNA analysis shows that their DNA is almost identical with only minor changes.
The diversity in environments on each island provides many opportunities to study how related organisms have adapted over time.
Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment.
Answer:
Explanation:
50 % chance is the correct answer
For #1, the last choice is correct. A geocentric model means that the earth is the center of the universe while all other bodies orbit around it. A heliocentric model means that the sun is the center of the inverse while the other bodies orbit around it. The shared feature is that the other bodies in space move in circular orbits.
For #2, the first answer is correct. When the moon is between the earth and the sun, positions X and Z are being pulled by the moon’s gravitational force, creating high tides at these places. However, positions W and Y are experiencing low tides because no gravitational pull is making them high.
Answer:
12-day litter weight is a trait that has an important genetic influence and therefore also a high response to selection
Explanation:
Heritability is a statistical measure of how much of the variation in a given trait can be attributed to genetic differences and how much of trait variation is due to environmental factors. A heritability value close to 1 indicates that almost all of the variability is due to genetic factors, while being poorly influenced by environmental factors. In this case, 12-day litter weight is a trait that exhibits an important genetic component (i.e., a high heritability value), thereby the correlation between parent and offspring will be high and lines selected for this trait will show a high response to selection.
Answer:
Interstitial fluid has a very specific composition, compared with plasma, and is responsible for providing the oxygen and nutrients required by the metabolically active Sertoli and germ cells, which are otherwise located in an avascular environment
