Tha main components in blood are the plasma, red blood cells, white blood cells, and blood platelets.
Plasma is like the main component that makes up most of the blood. It has a light yellow color and it carries many substances including nutrients, waste, hormones and more.
Red blood cells are the reason why blood is red in color. They have a hemoglobin inside them which can help carry oxygen for the tissues and organs. In order to maximize the oxygen carrying capacity, they don't have a nucleus.
White blood cells can be divided into phagocytes and lymphocytes. Their main function is to protect us from diseases. Phahocytes and engulf and digest bacteria, while lymphocytes can produce antibodies.
Blood platelets can cause blood clotting which can stop us from bleeding forever. They're not cells, but just fragments of cells. They also don't have nucleus since they're not complete cells.
b. protozoa
One of the four species of protozoan in the genus Plasmodium is responsible for the acute or subacute infectious disease known as malaria.
<h3>A virus or a bacteria causes malaria?</h3>
- A virus or bacteria cannot cause malaria.
- Plasmodium, a parasite that often spreads through infected mosquitoes, is what causes malaria.
- A mosquito consumes Plasmodia that are present in blood when it feeds on an infected human.
<h3>How do protozoa cause malaria?</h3>
- The female anopheles mosquito bite is the primary method of transmission of malaria, a protozoan infection of the red blood cells.
- The Plasmodium genus of protozoa is what causes malaria.
- Four different types of malaria parasites can infect people: Plasmodium malariae, vivax, ovale, and falciparum

Answer:
"Action potential is a rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane with a characteristic pattern."
It is the mode through which a neuron transports electrical signals.
Explanation:
- Option - (a) is the best choice to choose from,
- <u>The refractory period :</u>
A second action potential cannot occur until the membrane has recovered or reestablished, this is the refractory period. The absolute refractory period coincides with inactivation of voltage-gated sodium channels which makes it impossible to generate another nerve impulse.
