14 What is one way that meiosis is different from mitosis? A In meiosis there is variation in the cells produced, in mitosis an exact copy of the cell is created. B In meiosis an exact copy of the cell is created, in mitosis there is variation in cells. C Meiosis occurs in all cells, mitosis occurs only in sex cells. D Meiosis produces 45 chromosomes mitosis produces 23 chromosomes.

## Step 1<br />The question is asking for a key difference between meiosis and mitosis. Both are processes of cell division, but they serve different purposes and result in different outcomes.<br /><br />## Step 2<br />Option A states that in meiosis, there is variation in the cells produced, while in mitosis, an exact copy of the cell is created. This is indeed a key difference between the two processes. In meiosis, genetic variation is introduced through processes such as crossing over and independent assortment. This results in four non-identical daughter cells, each with a unique combination of genes. On the other hand, mitosis results in two identical daughter cells, each with the same genetic material as the parent cell.<br /><br />## Step 3<br />Option B is incorrect because it reverses the roles of meiosis and mitosis. In meiosis, there is variation, not an exact copy of the cell.<br /><br />## Step 4<br />Option C is also incorrect. Meiosis occurs in sex cells (gametes), while mitosis occurs in somatic (non-sex) cells.<br /><br />## Step 5<br />Option D is incorrect as well. Meiosis results in four daughter cells, each with half the number of chromosomes of the parent cell (23 in humans), while mitosis results in two daughter cells with the same number of chromosomes as the parent cell (46 in humans).
