Answer:

they amplify the original signal manyfold.

Explanation:

A phosphorylation cascade can be described or is regarded as a sequence of events, where one enzyme phosphorylates another, causing a chain reaction, leading to the phosphorylation of thousands of other proteins.

Phosphorylation cascades is considered to be important because it plays a vital role in regulating many intra cellular processes such as growth, proliferation and cell division.

In conclusion , it should be understood that, cells make use of phosphoylation cascades for signal transduction, bringing outside stimuli to the interior of the cell, to stimulate a response.

Sedbober [7]

Answer:

This is an example of "Disruptive selection".

Explanation:

Disruptive selection occurs when selective pressure favor homozygous. In equilibrium, the two alleles might be present or one of them might be lost. If an environment has two extremes, then in these environments, both alleles are presented in homozygous.

The disruptive selection causes an increase in the two types of extreme phenotypes over the intermediate forms. Limits between one extreme and the other are frequently very sharped. Individuals belonging to one phenotype can not live in the same area as individuals belonging to the other phenotype, due to the traits differences between them, competition, or predation.

Populations show two favored extreme phenotypes and a few individuals in the middle. Individuals who survive best are the ones who have traits on the extremes forms. Individuals in the middle are not successful at survival or reproduction.

Color is very important when it comes to camouflage. Dark green caterpillars that live in dark foliage and light green caterpillars that live in light foliage can hide from predators more effectively and will live the longest. Intermediate colored green caterpillars that don't camouflage or blend into either will be eaten more quickly.

Overall, how has science impacted human health?

mixas84 [53]

Answer:

The correct answer is: C. Increased average lifespan to 78 in the US.

Explanation:

Science has impacted human health by increasing the average lifespan to 78 in the US. Over the last couple of decades, the life expectancy of Americans has increased significantly than what it was 200 years ago. This can be attributed to:

1. Vaccinations- Since the invention of vaccinations, diseases such as tuberculosis, cholera and polio which were major causes of death 200 years ago have virtually been eradicated in the US.

2. Abundant and safer foods available- Commercial and large scale farming has made a wide variety of nutritious foods easier to obtain.

3. Improved sanitation- Safer drinking water, sewage treatment and stricter food inspection has significantly reduced the rate of illnesses due to poor hygiene and sanitation.

In these ways, science has impacted human health by increasing the average lifespan to 78 in the US.
