We are given a 120-g solution containing 100 grams of water as the solvent and 20 grams of dissolved sugar as the solute. In this case, we just have to divide the mass of sugar by the total mass of the solution then multiply by 100 percent. Hence, 20 / 120 *100% is equal to 16.7 percent.

During mitotic cell division, one parent cell produces ___________________________. Question 1 options: one daughter cell nothin

Ainat [17]

In mitotic cell division, one parent cell produces <u>two identical </u><u>daughter </u><u>cells.</u>

The correct option is (d) Two identical daughter cells.

<h3>Mitotic cell division</h3>

In mitosis, the cell divides into two identical daughter cell that contains the same number of chromosomes as the parent cell.

It divides into five stages: prophase, metaphase, anaphase, telophase, and cytokinesis.
The different stages of this cell division are together called as mitotic phase (M).

Thus, the correct option is (d) two identical daughter cells.

Consider two pairs of grandparents. The first pair has 4 grandchildren and the second pair has 32 grandchildren. Which of the tw

schepotkina [342]

Answer:

The second pair of grandparents have approximately 12 to 19 boys as grandchildren.

Explanation:

The probability of a grandchild being a girl or a boy is same, i.e., $\frac{1}{2}$ .

The first pair of grandparents have 4 grandchildren.

The second pair of grandparents have 32 grandchildren.

If first pair of grandparents have between 40% to 60% boys as grandchildren then the number of boys are in the limit,

$(40\%\ of 4,\ 60\%\ of 4)=(1.6, 2.4)\approx(2, 3)$

Thus, the first pair of grandparents have approximately 2 to 3 boys as grandchildren.

If second pair of grandparents have between 40% to 60% boys as grandchildren then the number of boys are in the limit,

$(40\%\ of 32,\ 60\%\ of 32)=(12.8, 19.2)\approx(13, 19)$

Thus, the second pair of grandparents have approximately 12 to 19 boys as grandchildren.

So, it is clear that the second pair of grandparents are more likely to have between 40% and 60% boys as grandchildren.

Also according to the law of large numbers as the sample size increases the probability of an event gets closer to the theoretical probability.
