Answer:
Stabilizing selection
Explanation:
Stabilizing selection is the most common form of natural selection that is not easy to notice in a population as the change is less drastic. It occurs when average or intermediate phenotypes of a trait in a population are favored, while the extreme phenotypes of that trait are not favored by the forces of natural selection. Over time, intermediate or non-extreme traits become more common in the population, while extreme traits become less common.
Answer:
Because they require a WATER medium for reproduction
Explanation:
Ferns are a group of living organisms under the division; Pteridophyta while mosses belong to the group Bryophyta. Mosses are considered primitive and non-vascular plants because they lack true stems, leaves and roots or vascular tissues. while ferns possess these organs, hence, are said to be vascular.
However, ferns and mosses are poorly adapted to a terrestrial life i.e. life on land because they both require a water medium for their motile male gametes to swim and fertilize their eggs (female gametes).
The kidneys contribute to waste management by recycling metabolic products and converting toxic substances into less toxic ones.
Kidneys are an important organ of animals as they provide a channel for the disposal of body waste and simultaneously regulate the balance in the level of salt and water in the body.
Kidneys work as microfilters that are capable of eliminating dissolved and suspended forms of ammonia, uric acid, urea, creatine, creatinine, amino acids, excess salts, and water along with proper disposal of organic waste which altogether constitutes the metabolic waste of the body. These substances before being finally excreted from the boy undergo a last round of reabsorption.
