What is a B cell? Apex

Biology
2 answers:
kykrilka [37]3 years ago
7 0

Answer:

Explanation:

B cell is also called B lymphocyte. It is a type of leucocytes or white blood cell. Some of the B cells mature in the bone marrow into the plasma cells and some mature as memory cells. The plasma cells make antibodies which fight against the disease-causing pathogens which entered the body. Thus, B cells are associated with the immune system of the body.

Answer:

Laying the viral antigens activate specialized white blood cells called <em>B cells</em>. The <em>B cells</em> change into plasma cells, which can then create specific antibodies to attach to the viral antigens. Antibodies make the viruses clump together, so they are then easier for white blood cells to destroy.

Hope that helps!!

Which portion of the sperm contains the enzymes needed to penetrate the oocyte?
tankabanditka [31]
<span>The head of the sperm contains the necessary enzymes to help it penetrate the oocyte. The sperm cell is anatomically structured to have four parts which are the head, neck, midpiece, and a tail. Inside the head of the sperm are densely coiled chromatin fibers that contain the nucleus for helping the sperm penetrate the female fertilized egg necessary for reproduction.</span>

The main steps of photosystem 2 include which of the following
Anestetic [448]

Incomplete Question options not given

Photosystem II is the first protein complex in oxygenic photosynthesis's light-dependent processes. It is found in plants, algae, and cyanobacteria's thylakoid membrane.

  • The thylakoid membrane, which is a part of the chloroplast in plant cells, is where Photosystem I and Photosystem II are found.
  • The products of the light dependent processes are delivered to the light independent reactions as ATP and NADPH.
  • Water molecules are divided into oxygen atoms and hydrogen ions when photosystem II pulls replacement electrons from them.
  • The thylakoid compartment retains the hydrogen ions from the water.
  • High energy electrons are transferred from Photosystem II to Photosystem I in the electron transfer chain.
  • The high-energy electrons in the photosystem received energy from sunlight while they were there.
  • Photosystem I releases high-energy electrons into the atmosphere.
  • The high energy electrons join NADP+ and a hydrogen ion after going via an electron transfer chain.
  • ADP and Pi are combined to create ATP with the help of hydrogen ions passing via the ATP synthases.

So to conclude with we can say that the initial protein complex in the light dependent processes of oxygenic photosynthesis is called photosystem II. It may be found in plants, algae, and cyanobacteria's thylakoid membrane.
