C is the answer. Three codons code for a single protein.
<u>Answer:-</u> <em>Option C</em> - Includes two rounds of cell division.
<u>Explanation :-</u>
- A <em>Venn diagram</em> is used to depict all possible relations between different sets.
In the given venn diagram-
1. The region X will consist of the features that are <em>unique </em>in <em>mitosis</em>.
2. Region Z will consist of features <em>unique </em>to <em>meiosis </em>
3. Region Y consists of features that are <em>common </em>to both mitosis and meiosis.
- <u><em>Meiosis </em></u>is a process in which a cell undergoes<em> 2 rounds</em> of cell division known as meiosis I and meiosis II to<em> produce 4 cells</em> from a single cell.
- As a result of meiosis a diploid cell (2n) divides to form <em>4 haploid</em> (n) cells. Such type of cell division is known as <em>reductional</em> division since, there is reduction in the number of chromosomes.
- The process of meiosis takes place to produce the <em>gametes</em> that is the sperm and the ovum.
- <u>Mitosis </u>is a type of cell division in which a single cell goes under a <em>single round</em> of cell division and divides to <em>produce 2 cells</em>.
- In mitosis a diploid cell thus, gives rise to 2<em> diploid</em> cells.
- Mitosis is called <em>equivalent </em>division as there is no change in the number of chromosomes.
- The process of mitosis takes place to give rise to the <em>cells of the body</em>.
Thus, we can conclude that <em>both mitosis and meiosis</em> result in even number of cells that is 2 and 4 respectively.
<em>Mitosis</em> is responsible for <em>duplicating body cells</em> and forming <em>diploid cells</em>.
<em>Meiosis</em> includes <em>two rounds of cell division</em>.
Answer:
2.67 cells at 500x magnification...
Explanation:
So, four cells are present at 200x magnification and are covering the full diameter of lens. by using a 500x magnification, it means that magnification is increased 1.5 times. So, the number of cells visible will be decreased by a factor of 1.5. So, decreasing 4 cells by a factor of 1.5 means <em>2.66666666667</em> or <em>2.67</em> cells at 500x magnification. Resolution has to be increased by a factor of 1.5 to produce a view-able clear image of cells.
