Answer:
C
Explanation:
If the population is in equilibrium, the allele frequencies will be constant.
There is nothing about the heritability of dominant or recessive alleles that make dominant ones any more likely by nature. This rules out choices A and B.
Genetic drift mentioned in D refers to alleles leaving a population. Nothing like this was mentioned in the question, so count that answer out.
C is the only remaining answer by process of elimination. It is also the most logical choice. Directional selection refers to a process of natural selection wherein extreme phenotypes (notched leaves, or non-notched leaves) are favored. In this case, there may be some external pressure causing notched leaf plants to be more evolutionarily fit, meaning that they survive long enough to reproduce more and increase allele frequency of the dominant allele.
Answer:
Throughout the reflection, make sure you have a copy of the Student Guide and your data tables. Complete the paragraph by using the drop-down menus.
In this lab, you determined the relative ages of rock layers using the principles of relative dating. The
✔ law of superposition
says that a rock layer found closer to Earth’s surface is
✔ younger than
a rock layer that is deeper in Earth’s surface. The
✔ principle of cross-cutting relationships
states that intrusions are
✔ younger than
the rock layer they cut across. You also determined the absolute ages of rock layers using a
✔ mass spectrometer
. The data you gathered helped you identify an unknown fossil.
Explanation:
the checked ones are the right answers
As far as I remember, this process is called interstitial growth. I bet that the situation represented above expresses <span>interstitial growth. It would be much better if you shared some options, but I bet I am correct and do hope it will help you in some mesure. Regards!</span>
