Answer: a. the lowest trophic level
Explanation:
The keystone species is the one on which the entire ecosystem depends upon. It maintains a balance in the ecosystem. If this species is removed the ecosystem will drastically change. The members of the keystone species are abundantly available at the lowest trophic level. This will help in making a balance in a community or ecosystem. If some members die others will be available to survive others.

C and D, but it can be B, since it occurs during cytokinesis and it begins before mitosis ends.
Answer: These cells are our sex cells – sperm in males, eggs in females. During meiosis one cell? divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid. Meiosis produces our sex cells or gametes? (eggs in females and sperm in males).
Explanation:
Answer:
The correct answer is "cell lysis due to the effect of osmotic pressure".
Explanation:
The cell wall is a structure that brings protection from the outside world and also helps to maintain the cell's water balance. The cell wall prevents that the cells is exposed to a large amount of turgor pressure, making the cell turgid when it is under extremal conditions. Some antimicrobials, such as bacitracin, block cell wall synthesis which makes the cell unable to support turgor pressure, resulting in cell lysis due to the effect of osmotic pressure.
