Q6.2. There are many diseases that do not infect a person more than once, such as chicken pox
and measles. What is responsible for this lifetime immunity?

The innate immune response, because barriers to entering the body improve with age.

The innate immune response, because adults have more white blood cells than children.

The acquired immune response, because antibodies are developed from previous infections.

The acquired immune response, because it responds rapidly to broad classes of pathogens.

Answers

The responsible for this lifetime immunity is the acquired immune response because antibodies are developed from previous infections. The generation of antibodies is a response to these infections.

The acquired immune system eliminates pathogenic organisms and any toxic molecules they produce.

The acquired immune system has two mechanisms of action: humoral immunity and cellular immunity.

Humoral immunity, also known as antibody-mediated immunity, involves the activation of specific blood cells (B cells) and subsequent secretion of antibodies when in contact with a pathogen.

Thus, the acquired immune system develops specific antibodies as a response to infections (e.g., chickenpox and measles).

The following statement is incorrect. Change two words to make it correct.

Capillary action happens when water moves up a vessel against gravity. It is a result of density and solubility working together.

NEED HELP PLZ

Answers

Answer:

Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube (picture to right) is limited by surface tension and, of course, gravity.

Explanation:

:}

When the cohesive forces between the liquid molecules are greater than the adhesion to the walls, capillary action results. Surface tension and, of course, gravity set a limit on how high capillary action may raise water in a uniform circular tube (see image to the right).

What is Capillary action in plants?

Water is transported to the remainder of the plant by capillary action up the stems and roots. Through the plant, water is transported through capillary action.

Water (the liquid) molecules are drawn to the molecules of the stem's interior (the solid).

The purpose of this attraction is to help lift the water out of the ground and distribute it throughout the plant.

When the forces holding a liquid together—cohesion and surface tension—and the forces drawing that liquid to another surface—adhesion—are stronger than the force of gravity, capillary action takes place.

Therefore, through cohesive forces and surface tension, water moves up a vessel against gravity.

What does the term temperature control refer to

Answers

Answer:

the term temperature control refers to Thermostats .....

A device called a temperature controller is used to maintain a target temperature at a given level. The typical thermostat seen in homes is the most basic type of temperature controller.

What are the biological temperature control factors?

The hypothalamus, a region of the brain, controls our body's core temperature. The hypothalamus measures our body's temperature and compares it to the average temperature, which is around 37 degrees Celsius.

The hypothalamus ensures that the body produces and maintains heat if our body temperature falls too low.

Progesterone tends to encourage heat conservation and higher body temperatures, whereas estradiol tends to increase heat dissipation.

Therefore, a thermostat seen in homes is the most basic type of temperature controller.
