<u>Answer:</u>
The factor that contributes to aging is: A Cells stop dividing after 50 divisions.
<u>Explanation:</u>
- Normally after 40 to 50 divisions the cells stops dividing because they had already lost too much DNA for other divisions.
- So they eventually die, making the appearance like an aged person in any individual.
- As DNA is copied in every cell division process, they tend to loose small part of telomeres in each transfer process.
- Hence, after 50 divisions these cells fails to divide resulting in aging.

Answer:
C. Scientists agree that both genetics and environment are important in developing self-esteem.
Explanation:
Self-esteem can be defined as the level of confidence and self-respect possessed by an individual in himself or herself, as well as the believe that he or she is both worthy and valuable.
Generally, self-esteem can be measured as either to be low or high; an individual that feels depressed, pessimistic, needy, insecure has a low self-esteem while an individual that is optimistic, confident, has self-respect, happier has a high self-esteem.
Also, the level of confidence and self-respect an individual has in himself is greatly influenced by two (2) factors: genetics and environment.
Hence, the true statement about genetics and environment is that scientists agree that both genetics and environment are important in developing self-esteem.
This ultimately implies that, an offspring having parents with low self-esteem is likely to inherit that trait and become low in self-esteem during their adult life. The environmental factors that affect an individual's self-esteem are schools, friends, media, family etc.
