what hormone do the c-cells secrete, and what is the function of this hormone?

Answers

Answer:

Calcitonin is one of those critical hormones. Calcitonin is a hormone that the C-cells in the thyroid gland produce and release. It opposes the action of the parathyroid hormone, helping to regulate the blood's calcium and phosphate levels. How does calcitonin work?

The hormone that the c-cell secrete is calcitonin. The function of calcitonin is a hormone that regulates the amount of calcium in your blood by decreasing it.

What are hormones?

The important hormone is calcitonin. Calcitonin is a hormone produced and released by the thyroid gland's C-cells. It works in opposition to the activity of the parathyroid hormone, assisting in the regulation of calcium and phosphate levels in the blood.

Calcitonin is a hormone produced by the thyroid gland, which is a tiny, butterfly-shaped gland found near the throat. Calcitonin regulates how the body uses calcium.

Calcitonin is a cancer marker. Tumor markers are substances produced in the body by cancer cells or normal cells in response to cancer.

Thus, calcitonin is the hormone secreted by c-cells. Calcitonin is a hormone that controls the quantity of calcium in your blood by reducing it.

Which of the following best describes an antigen?

Answers

d.a protein that attacks foreign molecules

B. A recognition molecule on the surface of the cells.

What is antigen?

An antigen is a substance that is capable of triggering an immune response in the body. It is typically a foreign substance, such as a pathogen (e.g. a virus or bacterium), a toxin, or a non-infectious particle (e.g. pollen or dust), that is recognized by the immune system as being foreign and potentially harmful.

When an antigen enters the body, it is recognized by immune cells called B cells and T cells, which produce proteins called antibodies to help neutralize and remove the antigen. The antigen-antibody interaction is a key part of the body's immune response and helps to protect us against infectious diseases.

Antigens can also be present on the surface of our own cells, such as cancer cells or transplanted organs, and can trigger an immune response if they are recognized as foreign by the immune system.

Overall, antigens are important components of the body's immune system and play a critical role in protecting us against infectious diseases and other threats.

Answers

Answer: photoperiodism means the response of an organism to seasonal changes in day length. Photoperiodism isn't the same as Photoperiod because Photoperiodism merely refers to the potential of the plant to incite flowering relative to the changes in the photoperiod. Thus, photoperiod is a light duration or the length of day and night, while photoperiodism is the effect of light duration on the plant’s growth.

Answers

The relationship between the environment, human population and geological events is complex and multidimensional. While human activities can also have significant effects on geological processes, geological events such as earthquakes, volcanic eruptions and climate change can have significant effects on the environment and human populations.

What is an Environment?

The conditions and forces that surround an organism, population or community are called its environment. It includes all elements of the Earth, both living and non-living, such as the atmosphere, hydrosphere, lithosphere, and biosphere.

The environment is a complex system that living things interact with and influence how they survive, develop and thrive. This includes biological elements such as plants, animals, microorganisms and their interactions, as well as physical elements such as temperature, light, water, soil, wind and topography.

Therefore, the relationship between the environment, human population and geological events is complex and multidimensional.

A scientist hypothesizes that increasing the amount of salt in a body of water will decrease the number of plants that can live in the water. What is the independent variable?
Group of answer choices

Amount of salt

Amount of water

Temperature of the water

Number of plants in the water

Answers

Dependent and Independent variables are regarded as variables in mathematical and statistical modeling and of course in some other aspects.

The independent variable is this case is the amount of salt.

In this kind of scenario, one can think of independent and dependent variables in terms of cause and effect.  An independent variable is the variable we assume to be the cause, while a dependent variable is assumed as the effect. Therefore, with this case, the amount of salt would cause a decrease in the number of plants. While the effect of increasing the amount of salt would be seen in the number of plants.

Explanation:

Answer

The longest phase of the cell cycle is Interphase

The shortest phase of the cell cycle is the Mitotic phase

Explanation

In case of cells with a nucleus, the stages of the cycle are divided into two phases: Interphase and the Mitotic (M) phase.

During Interphase the cell grows and makes a copy of its DNA before moving into Mitosis.

During Mitotic phase the cell separates its DNA into two sets to create two genetically identical daughter cells.
