Describe both innate and acquired immune systems and the importance of vaccines.
lbvjy [14]

Answer:

Innate immunity is a non-specific immune system which provides defence against any pathogenic microorganism in early stages. It includes physical barrier such as skin, chemical barriers such as saliva, tears, et cetera, phagocytic cells such as macrophages, et cetera.

Acquired immune system is the one which develops after exposure to pathogen or antigen. It is highly specific in nature. It includes B-lymphocytes and T-lymphocytes. It includes the production of antibodies.

Vaccines are used to develop acquired immunity in people. The process is termed as vaccination or immunisation. Heat-killed or weakened pathogen or antigen is inserted into a person after which a person develops antibodies and memory cells against that pathogen or disease. So, the immune system acts more vigorously against that pathogen in secondary infection.

Thus, a person becomes immunised.

In your own words, explain how the changes in the temperature of ocean water causes movement of ocean water from one place to an
ipn [44]

Well, many people might associate this to the increase in the movement of particles that occurs along with the increase in temperature, but that might not be enought to move ocean water to different places.

I'd relate it to density. Because, the higher the movement of particles, the lover the density. Which means that if we start cooling and sinking bringing new water to the surface, and if that becomes a cycle, along with water currents, we can create a movement.

↑ In my opinion, that is a really good point, so you should elaborate more on how the water currents will affect the process, and that should be it.

Hope it helped,

Red pigment found in vertebrate blood that functions in oxygen transport is
Margarita [4]
The answer would be Haemoglobin.

The Haemoglobin is a red pigment found in RBCs of vertebrates that helps to transport oxygen to various tissues.
Vertebrate blood is bright red when it is oxygenated and dark red when it is deoxygenated. Some animals such as crustaceans or mollusks, use haemoglobin to carry oxygen instead of hemoglobin.

Hope This Helped!
