Is a post oak tree is a autotrophic or heterotrophic
Tcecarenko [31]
All plants are autotrophic.

Autotrophic means he doesn't need another living thing to live(for eating) but that he makes his own food (photosynthesis). (auto means itself).

Heterotrophic means he needs others to keep on living. Like animals. All animals need to eat and can't make their own food with only sunlight, CO2 and water. They need food, which may be plants or other animals. That depends on the animal.

A.They maintain the cell’s shape.

B.They regulate cell processes.

C.They protect the body from infectious agents.

D.They signal the immune system to destroy pathogens.

E.They speed up biochemical reactions.

F.They send electrical signals.

The correct answers are C and D.

Explanation:

B cells and T cells use different biological weapons to attack the pathogen. The first secrete proteins called antibodies, which are distributed via the blood or the exposed surfaces to the environment, such as mucous. Antibodies are glycoproteins that circulate in the bloodstream looking for antigens that cause some type of damage to the body. Antibodies recognize and neutralize pathogens in a highly efficient way. Once the antibodies are produced, they remain circulating in the bloodstream for several months, which generates immunity for a long period of time to a certain antigen, in other words, they are capable of recognizing other molecules (antigens) in a very specific way and forming stable complexes with them (immune complexes). Its appearance in plasma is part of the adaptive immune response, in what is known as a specific humoral response, constituting a very effective defense against pathogens.
