Answer:
they are living because they are animals.
Explanation:
<span>Gametes are haploid cells that fuses with another haploid cell during fertilization. For human being, the gametes are the egg cells and the sperm cells and human fertilization is the union of a human egg and sperm, which usually occur in the ampulla of the fallopian tube. </span>
Answer:
2. A change occurs in the environment.
4. Poorly adapted individuals have decreased survivorship.
1. Well-adapted individuals leave more offspring than do poorly adapted individuals.
3. Genetic frequencies within the population change.
Explanation:
The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.
Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.
Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.
Hence, the sequence of events is 2, 4, 1 and 3.
You would find:
Near the plasma membrane of the leading edge of the cell, and near the plasma membrane of the trailing end of the cell.
Hope this helps.
It eliminates certain genetic diseases or bad traits for the flock.
