Stabilizing selection and disruptive selection are both examples of natural selection that affect population variation. In stabilizing selection, the average phenotype is favored, selecting against extreme variation. Disruptive selection, on the other hand, selects for extreme phenotypes, while the average phenotype is selected against.
Stabilizing selection and disruptive selection are both examples of natural selection that affect population variation.
In stabilizing selection, the average phenotype is favored, selecting against extreme variation. For example, in a population of mice that live in the woods, natural selection favors individuals that blend in with the forest floor and have a brown coat, while lighter or darker mice stand out and are more likely to be preyed upon.
Disruptive selection, on the other hand, selects for extreme phenotypes, while the average phenotype is selected against. For instance, if a population of birds lives in an environment with two distinct food sources, those with short beaks may be better adapted to feed on small, soft fruits, while those with long beaks may be more efficient at capturing insects. Birds with medium-sized beaks may struggle to effectively exploit either food source.

Impulse transmission would be slower in the axon with myelin.
An "all" response would occur in the axon with myelin.
A "no" response would occur in the axon with myelin.
Impulse transmission would be faster in the axon with myelin.
A protective layer or sheath called myelin develops around nerves, including those in the brain and spinal cord. It is composed of fatty and protein components.
Electrical impulses may move swiftly and effectively along nerve cells thanks to the myelin coating. These impulses decelerate down if myelin is compromised. Multiple sclerosis and other disorders may result from this.
Each nerve cell has a myelin sheath, which is a type of sheath (neurons). The primary "body" or axon of a neuron is covered in a protective covering made of protein and fat (lipids).
Therefore, Impulse transmission would be faster in the axon with myelin.

B. the building of dams.
C. a slow recharge rate.
D. infiltration by acidic water.
Answer: Option A) sinkhole formation.
Explanation:
A sinkhole refers to any dug-out or depressed area of land where human
or animal waste (excreta) are deposited.
Now, since these wastes contains water and are biodegradable by microorganisms, the fecal matter could be infected and in turns infect groundwater.
The contaminated-groundwater poses danger due to disease-causing organisms like
- vibrio cholerae, causing cholera
- Salmonella typhi, causing typhoid outbreak present, and also reduces volume of suitable drinking water in the community
Thus, the answer is sinkhole formation
2)mass wasting
3)a glacier
4)a mudflow
Answer:
It is Glacier, I just did my assignment and got it correct.
Explanation:
Answer:
Proteins are synthesized in the body through a process called Translation. Translation occurs in the cytoplasm and involves converting genetic codes into proteins. Genetic Codes are assembled during DNA transcription, where DNA is decoded into RNA. The cell structures called Ribosomes. Ribosomes help transcribe RNA into polypeptide-chains that need to be modified to become functioning proteins.
