Explanation:
Whereas primary tissues allow for vertical growth, secondary tissues allow for lateral growth: they allow stems and roots to become wider. In roots, the formation of both secondary meristems involves the pericycle.
Answer:
C. Only one allele appears for that gene in that population.
Explanation:
This totally explains what happens during gene fixation because when it happens in a small population, it tends to make one of its allele to appear for the said gene.
Furthermore, fixation can be explained as the change in a gene pool from a situation where there exists at least two variants of a particular allele to a situation where only one of the alleles is left. In the absence of mutation, any allele must eventually be fixed or lost completely from the population. Whether a gene will ultimately be lost or fixed is dependent on selection coefficients and chance fluctuations in allelic proportions.
Answer: Im pretty sure it's the orbicularis oris muscle.
Answer: i am pretty sure the answer is B.
Explanation: the coatis will not die off, there will be more bc there won’t be as many Beatles to eat them. the number of Beatles has little effect on the boa constrictor’s because they don’t eat them and the sloths eat the boa, not the other way around. the fruit bar population will decrease bc there will be less Beatles for the strangler fig to eat
i’m sorry if this doesn’t help or is wrong, i’m just trying to use process of elimination
