HLA Testing is used to match organ and tissue transfer receivers
with well-matched benefactors. HLA is a type of blood test done to search for a
protein, which can be found on the exterior of leukocytes or also known as White

cells and foreign ones, as well as damaging bodies.
Answer: The nervous system is necessary for the survival of the organism.
Explanation:
The nervous system is the main center of control and coordination of the entire body. It regulates various activities in the body like breathing, movement, thinking, reasoning, feeling emotions, sleep and wake, reproduction, and other necessary functions. The brain and spinal cord are the two chief components of the nervous system. There are many neurons present in the brain. The neurons are the nerve cells that help in communication with the other cells of the body like muscles and gland cells. They receive the signals from all the body parts and direct them to brain for interpretation. Neurotransmitters are the chemical messengers that transmit messages between the neurons, and from neurons to the muscles or other cells of the body.
Answer:
Advances have been made in the field of agriculture, but much remains to be done in the field of human health.
Explanation:
Through biogenetics, many advances have been made in the field of agriculture, for example, thanks to the cultivation of plant tissues, plants have been obtained with phytogenetic improvements that are more resistant to the attack of viruses, bacteria or fungi, as in the case of potatoes, carrots and tobacco.
Studies have been made related to the isolation of bacteria with potential biofertilizers so that they can induce improvements in production in various agricultural crops.
There is still much to achieve in the field of human health and in the treatment of terminal diseases such as cancer and AIDS, I think that if it was possible to detect from before birth in the genetic material of each person what diseases will be born, improvements could be made opportune in the quality of life of a person at an early age.
