Answer: Effector cytotoxic T cells
Explanation:
Cells infected with a virus or another internal cellular infection are immediately killed by effector cytotoxic T cells.
Since chemical spills are very harmful to aquatic/land life for both plants and animals, plants probably wouldn't grow back and animals could be mutated or even killed, decreasing the population of that species. A volcano eruption, can be both good and bad, since a volcano can kill animals and plants, but ash from a volcano is extremely fertile, so plants can regrow, which in turn brings animals back so they can feed on those plants.
The answer is two identical copies of the parent cell
There are choices for this question namely:
<span>a. ilium
b. pubis
c. ischium
d. sacrum
</span>
The correct answer is the "ilium". The pelvis is composed of 3 bones that fuse to make the pelvic girdle (with the sacrum). These bones are the ilium, ischium, and the pubis. The ilium forms the superior border of the pelvis, the ischium is the inferior, the pubis is the anterior, and the sacrum is the posterior. Attached is an image of the pelvic girdle, not that the ilium is at the superior portion of the pelvis.
