Do you have more cells now than you did when you were five?

Answers

Answer:

No After your cell dies of another one come. Your cells are still the same

Explanation:

When you age, cells do divide and reproduce more cells. However when you age the reproduction process of cells gets slower and they can die off before they can reproduce. There can be many problems with your cells that can make cell count lower such as Atrophy, and Dysplasia. When you age, cells are a contributing factor of making you age. They can change your skin, face, etc.. So the answer would be no, you would not have more than you did when you were five.

a. No health issues arise without an interaction between genetic and environmental factors.

b. Health issues related to toxic environments can occur independent of genetic inheritance.

c. Health issues, such as depression, are related solely to environmental factors.

d. There is no known connection between environmental factors and health.

Answer:

Health issues related to toxic environments can occur independent of genetic inheritance.

Explanation:

The statement which is true about the relationship between genetic and environmental factors relating to health is, that health issues related to toxic environments can occur independently of genetic inheritance.

What do you mean by Genetic inheritance?

Genetic inheritance may be defined as a principle that explains the process of characteristics that are passed from one generation to the next.

The toxic environment is responsible for the number of health diseases among organisms. These diseases may reflect the pattern of genetic inheritance as well, but it is not significantly accepted or analyzed.

Genetic inheritance depends on the physiological characteristics of involving parents.

Therefore, the statement which is true about the relationship between genetic and environmental factors relating to health is, that health issues related to toxic environments can occur independently of genetic inheritance.

Answer:

Electron Transport Chain

Explanation:

Gizmos Cell Respiration

The H+ that's vital in making ATP synthase work comes from the electron transport chain.

The electron transport chain can be found in the mitochondria. It is a series of protein complexes that are able to transfer electrons from the electron donors to the electron acceptors.

It should be noted that the transfer of the electrons from the electron donors to the electron acceptors is done through the redox reactions. This is illustrated in the H+ that made the ATP synthase work.
