Dragonfly species A (with a carrying capacity of 1,000) and species B (with a carrying capacity of 400) are competing. The competition coefficient of species A on species B is
0.25, and the competition coefficient of species B on species A is 0.5. Dragonfly species C (with a carrying capacity of 5,000) and species D (with a carrying capacity of 10,000)
are also competing. The competition coefficient of species C on species D is 0.1, and the competition coefficient of species D on species C is 0.2. Based on Lotka-Volterra
competition analyses, which of these pairs of species can coexist? Explain your answer.
Both can pairs can exist…. But why??

Option A : the fern transitined from gametophyte generation to sporophyte generation.

The Parker probe.

Explaination:

A spring is a natural discharge point of subterranean water at the surface of the ground or directly into the bed of a stream, lake, or sea. Water that emerges at the surface without a perceptible current is called a seep. Wells are holes excavated to bring water and other underground fluids to the surface.

99% percentage of errors does our body's "auto-correct",system detect.

Errors associated with protein mismatch and translation is automatically detected by the body system. Once, mismatch occurs, synthesis stops, hence, this error is almost always detected at all times. Therefore, the percentage of errors automatically detected is about 99%.

Explaination:

The lining of the trachea consists of a type of tissue called pseudostratified (ciliated) columnar epithelium.

Air is thinner at higher altitudes which means there are fewer oxygen molecules per volume of air. This means that when athletes train at these high altitudes, their body produces more red blood cells. These extra blood cells stay in the body for up to 20 days.
