Answer:

Through Mutation

Explanation:

Since our cells are able to produce exact copies of themselves. Thus, until unless some mutation has occurred and affected the ability of the cells to produce exactly similar duplicates copies of the parent cell, there is no way that an individual gets aged.  

Since, mutation affects the mitochondrial DNA it is pretty sure that a mutated cell has affected the longevity of a normal cell and then that mutated cell has produced million other mutated aged cell by replicating itself

Answer:

Is altered by mutation with time.

Explanation:

The older the age more is the process of aging. The aging includes both physical and psychological. The cellular duplication is a process of cell division called mitosis that produces exact copies of the original ones. The mitochondrial DNA mutation with the age is a cause of ageing. The mutation in somatic cells causes decrease in the function of such cells. The somatic mutations are one of the cause of decreasing the ability of cells to make exact copy of it.

Thus, the concept of aging as a result of cellular duplication errors is based on the fact that the body's ability to make new cells that are exact copies of the original ones is altered by mutation with time.

What might happen if one of the nucleotides were damaged or chemically altered just before the copying process
Veseljchak [2.6K]

Answer:

reacting with nitrogen and oxygen atoms in DNA, these compounds modify certain nucleotides so as to distort the normal pattern of base pairing. If these modified nucleotides were not repaired, they would allow an incorrect nucleotide to be incorporated during replication.

How is mitosis different in plants and animals
ValentinkaMS [17]

Answer:

The most important and observable difference in the plant animal cells mitosis is the cytokinesis. In plants a new cell plate is formed between the daughter cells for the future cell wall, while in animal cells the cell membrane constricts to separates the parent cell into daughter cells.

As children get older, cultural influences on behavior become much stronger; and as a result, it becomes difficult, if not impos
DanielleElmas [232]

Answer:

False

Explanation:

Sex is a biological term and gender is depended on the roles performed by an individual. In our society it is mandatory for a man or woman to behave and develop sexual preference for its opposite gender and this conservative thought process had strongly held the base of defining a sexual acts which is intended to happen between a male and female only.

However, this is not something defined by nature but by individual likeliness. This is the reason why even after being a male by sex, a male by gender can have likeliness for another male. This is something which cannot be bounded by social and cultural belief even after being into it for years.

Hence, the given statement is false

Know what makes a solution acidic or basic (the pH number and the ions).
Brrunno [24]

To determine whether an acidic or basic solution, it is first necessary to compare the concentrations of the hydronium (H3O +) and hydroxide (OH-) ions in the solution.

In acidic solution, the concentration of H3O + ions is higher than that of OH- ions.

  • In acidic solution, the concentration of H3O + ions is higher than that of OH- ions. Such a solution can be achieved by adding a small part of the H3O + ions, for example. Acid solutions have a pH below 7, the further away from 7 the pH of the solution is the higher its acidity content.  According to Le Chatelier's principle, when a disturbance is caused to an equilibrium system, it tends to readjust in order to diminish the effects of that force. This means that if an acid is added to water, the H3O + ions will be in excess and the equilibrium will shift in the opposite direction to the left. Then these excess ions will react with the OH- ions. Thus, the concentration of OH- ions will decrease and the solution will become acidic.
  • In basic solutions, the concentration of OH- ions is higher than that of H3O + ions.  If we add a base to the water, it means that we will be adding OH- ions and, as explained in the previous section, by Le Chatelier's principle, the equilibrium of the water selfionization reaction will shift in the opposite direction, and the excess ions will react. with the H3O + ions, decreasing their concentration and making the basic solution.  Basic solutions have a pH greater than 7, the farther from 7 and closer to 14 the pH of the solution, the higher the basification content.
