Keratin is a fibrous protein, that makes up a large component of the hair and nails. It is a hardened protein, with some flexibility, that is used by epithelial cells to protect the cells from damage and stress, when the hair or nail is still in the roots. It is found in high amount, in vegetables and fruits that are orange in color (carrots in particular)
The number of neutrons in a helium atom is TWO (2).
- Helium (He) is the second chemical element in the periodic table.
- Helium consists of two (2) protons and two (2) neutrons in its atomic nucleus.
- In consequence, the atomic number of helium is equal to two (2).
- The Sun contains approximately 25% He, which is generated by solar fusion.
In conclusion, the number of neutrons in a helium atom is TWO (2).

Environmental factors often influence traits independently of genes. Either of these effects can change the proteins that are made from a gene, which in turn affects traits.
How do environment and gene determine our personality?
Some genes increase the characteristic and others work to decrease the same characteristic-complex relationship among the various genes, as well as a variety of random factors, produce the final outcome.
Because of their genetic makeup, individuals differ in their responsiveness to the qualities of the environment. There are unique, genetically influenced reactions to particular experiences to which we are exposed.
The presence of drugs and chemicals in an organism's environment can also influence gene expression in the organism. The environment can affect morphological and physiological development whereas genes influence morphology and physiology, creating a framework within which the environment acts to shape the behavior of an individual.
Hence in this way, genes and environmental influences work together to determine our characteristics.

Explanation:
Cytochromes are found only in the mitochondrial membrane as part of the electron transport chain. They are vital to the downward cascade of energy as electrons are passed from the NAD+ and FAD produced during glycolysis and the Krebs cycle into the electron transport chain to eventually produce ATP.
