Answer: T-cells are made to identify antigens, while inflammation fights anything in the affected area

The adaptive immune cells are made of B-cell and T-cell. The function of B-cells is to produce antibodies, while T-cells will detect antigens of the pathogen. If T-cells detect an antigen from a cell, it will assume that the cells are infected. It will send a signal to the infected cells which tell them to do apoptosis. Inflammation is not specific, which makes them not strong.

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.

Which of the following is a process in which carbon is released back into the atmosphere?

bagirrra123 [75]

Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.

We breathe more quickly and deeply when we exercise. Why does this make sense? Select all that apply. a) Because when we exercis

storchak [24]

Answer:

a) Because when we exercise, we hydrolyze more ATP to ADP and Pi, and O2 is necessary for the hydrolysis, so we increase our intake of oxygen.

c) Because when we exercise, we produce more CO2 and increased ventilation is necessary to rid ourselves of CO2.

d) Because when we exercise, we use more ATP, and additional O2 is necessary to generate sufficient ATP.

Explanation:

During exercise , our body needs more energy in the form of ATP. This ATP comes from break down of food materials in the mitochondria of the cell during cellular respiration. With the addition of oxygen, more ATP is produced during respiration and this ATP is used by the body. With ATP, carbon dioxide is produced as a waste material which can be removed by exhaled out during breathing.

A bird flies at 12.5 meters per second. the wind speed is 4.5 meters per second. what is the speed of the bird when it flies wit

Agata [3.3K]

Answer:

17m/s

Explanation:

Given parameters:

Speed of the bird = 12.5m/s

Speed of the wind = 4.5m/s

Unknown:

Speed of the bird when it flies with the wind = ?

Solution:

The speed of the bird when it flies with the wind is the sum of the speed of the bird and the speed of the wind.

Speed of the bird with wind = 12.5m/s + 4.5m/s = 17m/s
