Heredity.
It helps explain why children tend to resemble their parents, as well as how a genetic disease runs in a family, although some genetic conditions are caused by mutations in a single gene.
Nucleus can be defined as a large organelle found in the Eukaryotic cells and it is also know as the cell's command center,thus it controls the activity of the cells
Explanation:
- The answer to the above question is (c )nucleus. During the cell cycle the nucleus of the cell mediates the replication of the of the DNA and controls the gene expression.
- The nucleus contains a structure which is known as nucleolus and which is made up of protein and ribonucleic acid(RNA)
Answer:
5.0 × 10^8 cells.
Explanation:
Mass of DNA = 2 × 10^-12 g/cell
Mass of DNA to be isolated = 0.001 g
No of cells = 0.001/2 × 10^-12
= 5.0 × 10^8 cells.
Answer:
<u>Major limitation of Jorge's experiment are -:</u>
- Vast amounts of data can be obtained.
- He does not prove definitively that a person is taller because of vitamins.
- No association between vitamins and height can be seen.
Explanation:
<u>ABOUT VITAMINS -:</u>
A vitamin is an organic molecule that is an important micronutrient that an organism requires in limited amounts for the proper functioning of its metabolism (or a chemically closely connected group of molecules, i.e. vitamins). In the body, basic nutrients can not be synthesized in adequate amounts, either at all or not, and must therefore be ingested via a diet.
Hence, the major limitations of the experiment are mentioned above.
