The statement is true. Dead zones are the zones of oxygen depletion, which is caused by excessive running off of the fertilizers into the water body. These chemicals, particularly the nitrates, which are used by algae etc. which bloom by using the nitrates and use the oxygen present in the water. When they die, oxygen levels become critically low till then, for other aquatic animals like fishes etc., to survive.
Answer:
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
Explanation:
<span>The process is called Precipitation.
Water evaporated into the atmosphere. Due to the very low temperature of the
atmosphere, the vapor condenses and it is turned back into a non-gaseous form,
and because of gravity, it falls back to the ground in various forms, such as
rain, snow, sleet, or hail. </span>

Answer:
A. True
Explanation:
Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.
Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.
