Which of the following best describes an antigen?
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.

We need to recycle our waste because Earth is a closed system with respect to
matter, and new matter does not enter the environment. Agree or disagree
I disagree because although recycling is good, Earth firstly is not a closed system and new matter enters the environment all the time, such as comets.
In terms of matter, the Earth is often referred to as a closed system. In other words, the total amount of matter on Earth neither changes nor becomes more or less; Instead, it can take on different forms due to different processes. So, I am agree with this statement.
Although the Sun provides the world with continuous energy, most of the actual matter on Earth is recycled and used in various cycles. Recycling of waste is important because it enables us to recover useful materials and resources, reducing the need for mining new raw materials from the earth. Recycling helps us to reduce the environmental damage caused by the extraction and disposal of waste as well as the depletion of natural resources. It helps maintain long-term equilibrium inside a closed system of matter on Earth.

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

can someone explains (summarize) what photoperiodism is? And if it’s the same as photoperiodism
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.

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
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.Learn more about dependent and independent variable: https://brainly.com/question/25223322
