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.

Stomata - specialized cells that contract and expand to open or close pores for _______________. Stomata can adjust to temperatu

adoni [48]

Answer:

Stomata - specialized cells that contract and expand to open or close pores for gas exchange. Stomata can adjust to temperature, staying closed when temperatures are hot and dry to prevent gas and water loss.

Explanation:

Stomata (singular stoma) are pores found in the epidermis of plant leaves. Stomata open and close in response to the change in structure of two guard cells either side of the pore opening. When the guard cells are turgid, the stomata open, when they are flaccid, they are closed.

This functions to permit gas exchange while preventing the loss of water, especially during hot, dry weather. The stomata can only open when the guard cells are turgid, pulling the stomata apart.
