The chemical reaction could be vary with the condition but the nuclear decay rate is constant, here the option A is the right option.
If a mutation occurs in the skin cell, it only affects that individual. However, a mutation in the sperm or egg results in altered DNA, which can be passed onto the offspring. Eventually, this can result in genetic changes which are either favored or not. This relates to the survival of the fittest because those with mutations that help individuals survive pass those mutations onto their offspring.
Answer:
C
Explanation:
The heart moves the blood which contains the materials the cell needs and the materials from the cells
The two halves of a duplicated chromosome are called chromatids, and they are formed during the interphase of mitosis. Mitosis is the process of cell division that results in two daughter cells. Chromatids stay together during interphase but separate shortly thereafter, during anaphase.
In anaphase, the chromatids split apart, moving to opposite sides of the cell. Once separated, the chromatids become actual chromosomes, each containing one piece of DNA.
A human cell forms 92 chromatids during interphase. Once the chromatids separate during anaphase, two separate groups of 46 chromosomes are formed. The final phase of mitosis is telephase, which involves nuclear membranes forming around the chromosomes.
Answer:
b. a greater chance to survive if environmental conditions suddenly change
Explanation:
When a species of organism has a wide variety of characteristics, it means that that species has many opportunities to adapt and survive different environmental conditions, even if those conditions change suddenly. This is because, this variety of characteristics allows this species to adopt the most variable survival strategies.
