Explanation:
Compound growth
Equation:
20000 x 1.05 to the power of how ever many years needed
20000 x 1.05 to the power of 15 takes it just over, with 41578 people alongside decimals.

Since the blood does not return to the heart after flowing
through the gills, pressure is not regenerated within the system before it
flows to the systemic circulation (the rest of the body). A single circulation
would experience a loss of pressure after flowing through the gas change organs
(gills of a fish) due to the high cross-sectional area presented by the
capillaries of the gills. For ectotherms like fish, this is efficient enough to
support their activity level. A fishes behavior would change in a few ways if
it had an open circulatory system. However, the most common would be the fish
would become extremely active.
The structures B and C have in common is that both contain partially disgested food. Thus, the correct option is B.
<h3>
What are structures B and C here represent?</h3>
Structure B represents the food pipe or esophagus, while structure C represents the stomach.
Chyme is produced only when food is fixed with gastric juice which is only present in the stomach, hence option A is incorrect.
Waste material is found in the rectum of the body structure, not in the esophagus and the stomach. Thus, option C is also incorrect.
Therefore, the correct option is B.
