Answer:
American's portion sizes have become larger in the last decade due to the expanding of food industries and marketing campaigns that tell us to eat more.
Explanation:
The growth of food industries in the last decades to obtain more money in combination with the media influence has led us to eat more, thus why the size of our portions has increased their size.
Another theory states that people always want to eat more, and the industry has only fulfilled this demand, but it is not clear why, in the past, this did not happen.

Answer:
The correct answer is : 0.264
Explanation:
The total population of the Soay sheep is : 368 dark sheep + 132 light sheep
= 500 sheep.
Total dark coat sheep ( dark allele represented by D as it is dominant) = 368
Total light coat sheep ( light allele represented by d as it is recessive) = 132
As we know crossing is took place in between true breeding:
DD × dd
F1, Dd ( all are dark coat)
So, the genotype frequency of the homozygous recessive allele is
= 132/500 (by Hardy - Weinberg equation)
= 0.264
Thus, the correct answer is 0.264.
