To keep warm your body shivers and your blood pressure decrease, it brings the blood back to the heart to keep you warm, also in you blood, your hormones create glucungons that makes the liver shoot out glucose to keep you warm. To keep cool you body sweats and in you blood the hormones create something called insulin that makes you cell take in the glucose in you blood.(Fun Fact: the things that I just said are negative feedback).

The nervous system includes the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment.

• Neurons are the basic unit of the nervous system. All cells of the nervous system are comprised of neurons. Neurons contain nerve processes which are "finger-like" projections that extend from the nerve cell body. The nerve processes consist of axons and dendrites which are able to conduct and transmit signals.

• The brain is the control center of the body. One of these furrows, the medial longitudinal fissure, divides the brain into left and right hemispheres. Covering the brain is a protective layer of connective tissue known as the meninges.

• The spinal cord runs down the center of the protective spinal column extending from the neck to the lower back. Spinal cord nerves transmit information from body organs and external stimuli to the brain and send information from the brain to other areas of the body.

Does Ajay’s diet provide enough protein to meet his RDA of 0.8g/kg of body weight? (2.2lbs = 1kg)

Answer:

The correct answer is yes.

Explanation:

RDA or recommended dietary allowance refers to the minimum amount of a nutrient, that is, regarded as essential for the proper functioning of the body or to sustain good health. The RDA is formulated by the Nutrition Board of the National Research Council.

In the given case, the weight of Ajay is 154 pounds. In terms of kilograms, 1 kg is equivalent to 2.2 pounds.

Thus, 154 pounds will be equal to 154/2.2 = 70 Kg.

Based on RDA, the requirement of protein for a healthy individual should be 0.8 g/kg of the body weight. Therefore, Ajay needs to consume 70*0.8 = 56 grams of protein. However, based on his diet he is consuming 78 grams of proteins in a day. Hence, it can be concluded that Ajay is consuming adequate protein to meet his RDA.
