A sperm joins an egg cell in the process of fertilization. Because first both of the parents must contribute one gamete, then the sperm and egg unite in the process called fertilization, and finally this process forms a single celled structure called a zygote which contains the full genetic information that will be passed to the offspring. And now the offspring will have half of it's genetics from both of it's parents.
I know all of this because I just learned, studied, and took a test on this topic. Plus I checked Google just to make sure I was correct. Hope I helped you!

Answer:
A clade is a grouping that includes a common ancestor and all the descendant species of that ancestor. Clades are differentiated visually based on where they branch off from one another.
Explanation:
A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor. Using a phylogeny, it is easy to tell if a group of lineages forms a clade. Imagine clipping a single branch off the phylogeny — all of the organisms on that pruned branch make up a clade.
Clades are nested within one another — they form a nested hierarchy. A clade may include many thousands of species or just a few. Some examples of clades at different levels are marked on these phylogenies. Notice how clades are nested within larger clades
Answer:
Euglena is a large family of unicellular protists: they have both animal and plant characteristics. All of them survive in water, and move by the help of a flagellum. This is an animal characteristic. Most of them hav chloroplasts, which r the characteristic of plants.
Explanation:
The founder effect<span> occurs when a portion of the </span>population<span> (i.e. "founders") separates from the old </span>population<span> to start a new </span>population<span> with different allele frequencies. </span>Small populations<span> are </span>more<span> susceptible </span>genetic drift<span> than large</span>populations<span>, whose larger numbers can buffer the </span>population<span> against chance events.
