Are puffballs unicellular?
Pollen is not unicellular. This is because pollen is not yet living and is only acting like a spore would act.
What is a substance usually a protein that causes the formation of an antibody and reacts specifically with that antibody?
An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).
What is a monovalent antigen?
A monovalent antigen is a type of antigen that contains only one type of epitope, which is the specific molecular structure that can be recognized by the immune system. This means that the antigen can only trigger a response from one type of antibody.
Which term describes any substance that the body regards as foreign?
antigen
Can a receptor be an antigen?
No, they are entirely two different things. What might stimulate a receptor could be an antigen.
What is a sentence using the word 'antigen'?
For some people, bee pollen acts as an antigen and gives them hives.
What are 3 examples of an antigen?
An antigen is a foreign substance that provokes an immune response in the body. Examples of antigens are: bacteria, pollen grains and large carbohydrates.
How does antigen work?
An antigen is a substance or molecule that, when introduced into the body, triggers the production of an antibody by the immune system, which will then kill or neutralize the antigen that is recognized as a foreign and potentially harmful invader. These invaders can be molecules such as pollen or cells such as bacteria.
What is antigene and antibody?
An antigen is a substance that can invoke an immune response. While an antibody is the immune system's response to an antigen. Antibodies, act by directly neutralizing the antigen and/or bind to the antigen and signaling marcophages to phagocytose the antigen.
What all can act as an antigen?
An antigen can be any substance that elicits an immune response, including proteins, polysaccharides, lipids, and nucleic acids. Common examples include pathogens like bacteria and viruses, as well as non-infectious substances such as pollen, certain foods, and transplanted tissues. Even small molecules, when attached to larger carrier proteins, can function as haptens and act as antigens. Overall, antigens are diverse and can originate from both external and internal sources.
What is the alternative name for antibody?
An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment, such as chemicals, bacteria, viruses, or pollen. It could be also called an irritant.
What is the act of moving pollen from the stamen to the pistil?
This act is called pollination. It helps in sexual reproduction.
Is the pollen transferred from the pistill to the stamens?
It's a reproductive act.
Why is pollen transferred from the pistill to the stamens?
It's a reproductive act.
Are puffballs unicellular?
Pollen is not unicellular. This is because pollen is not yet living and is only acting like a spore would act.
Pollen grains often stimulate an allergic response that produces?
Pollen grains contain proteins that can trigger an allergic response in some individuals. When inhaled, these proteins can cause the immune system to mistakenly identify the pollen as harmful, leading to the release of histamine and other chemicals that result in allergy symptoms such as sneezing, itching, and congestion.
