Both prokaryotic and eukaryotic cells can have flagella but they are very different from each other. Flagella are used to help the cell move around.
Answer:
1. b. a founder effect
2. a. keeping the sex ratio as close to 50:50 as possible
Explanation:
The founder effect is a phenomenon that occurs when a small subset of individuals split from a larger population in order to establish a new colony. The founder effect is known to cause a reduction in genetic variation of the colony due to genetic drift, i.e., due to the random sampling of the individuals that form the colony (which doesn't reflect the total genetic diversity of the original population). Moreover, the sex ratio refers to the proportion of males to females in a population. When establishing a captive population, it is recommended to maintain a sex ratio as close to 50:50 as possible because it reduces inbreeding, and thereby mitigating the loss of genetic variation. In some populations, it has been proposed that a 50:50 sex-ratio might also increase the competition between males, which is believed to be fundamental for maintaining a healthy genetic structure of the population.
