Interphase is the period of the cell cycle where the cell is actually growing, developing, and carrying out cellular processes. Essentially, interphase is when the cell is busy being a cell. It grows, synthesizes proteins, replicates its DNA, and so on and so forth.
<span>Mitosis is only the small portion of the cell cycle when it is dividing into two new cells. The rest of the time (interphase), the cell is performing its various functions.</span>
The foreign molecule that activates the immune system are Antigens.
Answer:
Active Transport
Explanation:
Active transport is the process of transport of substances from region of their lower to that of higher concentration. Since the transport occurs against the concentration gradient, it is energy requiring process and needs input of energy to occur.
In given example, liver cells transports vitamins against the concentration gradient in energy dependent manner. Therefore, it is an example of "active transport".
Answer:
Option B
Explanation:
The three categories of petites are segregational, neutral, and suppressive and both nuclear and cytoplasmic (mitochondrial) genes contribute to the petite phenotype in some cases. Suppressive petites are characterized by perfoming crosses between petite and wild-type and discovering that all offspring are petite, this exhibit a "dominant" behavior which suppresses wild-type mitochondrial function and not a lack of mitochondrial function.
