Answer:

scientists have developed four different methods of determining the age of the earth. By using these methods, or a combination of them, the age of geological formations created by past events and even the fossilized bones of prehistoric animals can be determined.

Based on the research done by scientists, the Geologic Column, a graph that illustrates earth age, was developed. The Column, with its names for the epochs and eras of time, illustrates what scientists think was taking place in earth history. The three primary methods are:

Radiation Measurement

Stratigraphic Superposition

The Fossil Record

From these methods of dating, scientists have determined that the earth as we know it seems to be about 4.6 billion years old. It is theorized that the earth got its start as a result of what is called the "Big Bang nearly 6 billion years ago. The Big Bang theory holds that all the planets, stars, solar systems, galaxies, etc., are the result of a huge explosion that sent material speeding through space. As time passed, the gravitational force of larger chucks of material attracted the smaller chunks and formed the galaxies and solar systems we see today.

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).

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.

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).

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.
