Since plants require sunlight in order to produce light, they need to be exposed to it. Now, since there are other plants attempting to do the same they have to grow higher so they don't get put in the others shadow and possibly die due to lack of sunlight.
Answer:
C) it is necessary for the survival of the individual.
Explanation:
Sexual reproduction is rarely, if ever, necessary for the individual. This is not a reason for its importance. However, while not important for the individual, sexual reproduction is important for the species. It allows genetic variability among offspring, as well as mutations. This ensures that not all members of a species are the same, and in this way, they have a better chance of surviving. Moreover, it allows for offspring to be produced at a faster rate.
Answer:
See the answer below.
Explanation:
<em>Let the allele for eye color be represented by A. Blue is dominant over brown eye color, hence, blue allele would be A while brown eye allele would be a.</em>
Two parents have the genotype blue/brown which is equivalent to Aa.
Aa x Aa
AA 2Aa aa
blue eyes blue eyes brown eyes
a. Different possible outcomes: AA blue eyes, Aa blue eyes, and aa brown eyes.
b. Probability of a child from the cross having brown/brown (aa) genotype = 1/4 or 25%
c. Probability that the child would have blue eye color = 3/4 or 75%
