The answer is Both result in a change in allele frequencies in the affected population
Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms. I<span>magine you have two different alleles in the population responsible for red and white color of a flower. Their allele frequencies are 0.2 for white flowers and 0.8 for red flowers. After some change in the environment, only white flowers survive. They will reproduce, and in the population, there will be only white flowers. The population for these flowers will increase from 0.2 to 1.
Speaking of gene flow, it is not as dramatic and drastic as genetic drift, but still, it includes a transfer of alleles from one population to another, so there is expected a change in allele frequency.</span>
Answer:Objective questions
Explanation:
Answer:
The cells (Osteoclasts) are found i believe around the bone to protect it from breaking or if it already is broken those cells help remodel or fix it back in place
Hope this helps
Explanation:
<span>Both the populations of Drosophila seem to have the same gene for foraging behavior
Therefore, the </span><span>alternative hypothesis which is made far less likely by having three R and K lines, rather than one of each is:
</span><span>The difference between the R and K lines is the result of environmental differences in the food availability of their habitats.

TEMPURATURE:
Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working.
pH:
Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature.
DIFFERENT SUBSTRATES:
Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.
I got these explanations from khan academy :)
