Answer: What has genetic engineering been used to produce?
Explanation: A
The probability that at some point in the future allele k will drift to a frequency of 1.0 is 0.5 because genetic drift is a random and non-directional mechanism of evolution that significantly alters the gene or allele frequency in any population.
<h3>What is Genetic Drift?</h3>
Genetic drift may be defined as a mechanism of evolution in which allele frequencies of a population changes over generations due to chance (sampling error). It is more effective in small populations.
The outcome of genetic drift can not be predicted because it is a random and non-directional mechanism of evolution. It is possible that it fixes the allele k and makes its frequency 1.0, while it also alters the frequency of other alleles and makes the allele k eliminated from the given population. It is a process that depends on the phenomena of chance.
Therefore, it is well described above.

Answer:
c. Cell division increases the mass of the original cell.
Explanation:
Cell division is a process of formation of daughter cells by dividing the existing cells. As the cells grow, their surface area to volume ratio reduces which means that a larger cell has a less surface area than its volume as compared to a smaller cell. Cells need to maintain a higher surface area to perform various biological functions. Therefore, after attaining certain growth, cells divide to increase their surface area and reduce their volume. Cell division reduces the mass of the parent cell. The newly formed cells grow to increase their mass.
The answer is Body temperature
Circadian rhythm will regulate the daily circle of an organism. There is many biological aspect that could be regulated such as the hormone secretion, blood sugar, body temperature, and sleepiness. The migration of birds would be happen annually, not daily. The female menstrual cycle would be happened monthly too.
