Answer:
The 2 processes that occur in meiosis to create genetic diversity are <em>crossing over and independent assortment.</em> <em>Crossing over is when exchange of DNA segments occurs between homologous chromosomes. Independent assortment is when homologous chromosomes assort independently into gametes. </em>
Explanation:
Meiosis can be described as a process of cell division through which four daughter cells are produced having half the number of chromosomes as the parent cell.
During this process, the phenomenon of crossing over and independent assortment occurs which allows for the genetic diversity which we see in organisms of a species.
During Prophase 1 of meiosis 1, homologous chromosomes exchange segment of DNA between them which leads to genetic diversity.
During Anaphase 1 of meiosis 1, homologous chromosomes move to each side of the cell and the chances of the gamete to receive any of the chromosome is random.
Any organism that will eat something that is already dead
Answer:
C) genetic drift.
Explanation:
Genetic drift is the random change in the frequency of alleles in a population due to random sampling. Many circumstances can lead to genetic drift for example bottleneck effect, founder effect, etc.
The bottleneck effect occurs when most of the members of a population die because of any natural disaster like flood, fire, etc. This can cause a certain allele to be lost in the remaining population because of losing major populations. So here due to hurricane half of the mammal population gets eliminated which shows it is an example of the genetic drift.
The correct option is D.
Antibiotic resistant is said to occur, when a particular antibiotic has lost its capacity to effectively eliminate or control the growth of a particular type of bacteria. In this case, the bacteria continues to grow and multiply in the present of the antibiotic drug. Antibiotic resistant usually occur when a bacteria has develop a variation that makes it possible for it to inactivate the antibiotic drug that is used against it. A bacteria that is formerly susceptible to a particular antibiotic may later become resistant to the same drug by developing variations that inactivate the antibiotic drug that is administer to destroy it.
