As we inhale air, oxygen enters the respiratory system and the circulatory system to transport it to the other parts of the body and to all cells. As the oxygen is already transported, the blood becomes deoxygenated and carries a CO2 which returns to the lungs and then we exhale the carbon dioxide.
It main aim to give an overview about the effect of dietary nutrients on the structure and functions of brain. Brain which is elaborated from substances present in the diet such as vitamins, essential amino acids, fatty acids, omega-3 , etc.
Micronutients ( vitamins, trace- elements) have been directly evaluated in the setting of cerebral functioning. Nervous tissues use glucose to produces the energy and implies the presence of vitamin B1 , which perform cogitative functions, specifically in elderly. Vitamin B9 , which preserve the brain during its development .
Genetic potential of children for their physical growth and mental development may compromised due to deficiency of micronutrients. Their poor nutritional status are exposed to alterations of mental and behavioral functions that can corrected by dietary measure.

The characteristics that apply to viruses are;
- Viruses are made of RNA or DNA.
- Viruses have a protein coat
<h3>What are viruses?</h3>
Viruses are microscopic non-cellular structure consisting of a core of DNA or RNA (nucleic acid) surrounded by a protein coat (capsid).
A virus is considered as by non-living because it requires a living host cell to replicate, and often causes disease in the host organism.
Therefore, the characteristics that apply to viruses are;
- Viruses are made of RNA or DNA.
- Viruses have a protein coat

Answer:
In the mentioned case, both the cells will start to perform replication of their DNA. In the case of G0, that is, the stationary phase, the mammalian cell can pass the restriction point with the supplementation of extracellular proliferation signal. While in the case of G1, which actually does not require any kind of external proliferation signal, as once the cell is in G1 phase, it is ready to go get the next phase. However, both the mammalian cells will cease or halt at G2 checkpoint.
Blood plasma transports nutrients, waste (like uric acid, creatinine, and ammonium salts), albumin (protein), and electrolytes.
