Answer: This is the definition and example of Osmosis.
Explanation: Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a region of high concentration of solvent to a less concentration of solvent, thus making the concentrations on each side of the membrane equal.
The cell membrane is also a selectively permeable membrane which allows only certain substances to pass through it. Mostly molecules move from a side where their concentration is high to a side where their concentration is less to make the concentration equal on both sides.
what are you asking just to be clear
Answer:
Mutation is the alteration in the DNA base sequence in an organism.it may be due to chemical or environmental effect on the somatic cells..
Generally ,most cancers are caused by mutation in DNA components of abnormal cells.
Basically proto-oncogene is responsible for cell growth and cell division before mitosis in normal healthy cells;thus its codes for the main protein specific for cellular functions in normal cells. Therefore for mutation to occur mutations in mutiple genes is important. .
Basically 2 p53 alleles must be mutated,
2 BRCA1 allele must be mutated,
and 1 mutated allele of HER2 mus be mutated.
All these multiple mutations in these genes are needed.

Explanation:
Cell theory states that living things are comprised of cells, as their smallest units capable of functioning. Microscopy helps to prove this, as cells and their varying components can readily be seen, observed and later classified. Their components and molecules require the closed system of the cell in order to function with different arrangements and features being key to certain phyla, groups and species; this aided in the reclassification of organisms into the kingdoms and phyla we know today.
Theories are repeatedly testable observations about phenomena in the natural world; they are based on a rigorous review process, that, includes experimentation and evaluation.If new information about these phenomena is made available by technological advancement, novel observations can be incorporated into experiments, which would change cell theory.
