Answer:
The answer is the first option.
Explanation:
Farming emerged because being a nomad was no longer suitable for increasing population size. Farming allowed people to stay in one place and properly feed their families, which was a definite positive impact on population size.
Answer: p (short hair) = 0.91 and q (long hair) = 0.09
Explanation: In the population, short hair is a feature of domnant allele, because there are more short haired individuals than with long hair. In genetics, p is the frequency for dominant allele and q is for recessive allele.
For this question, short hair is allele L and long hair is allele l
So, the frequency of short hair is p and of long hair is q.
To calculate the frequencies:
Frequency of allele L = (number of copies of allele L in population) / (total number of L/l gene copies in population)
p = 182/200 = 0.91
The same formula goes for the recessive allele, so:
q = 18/200 = 0.09
Thus, the frequencies of hair allele are 0.91 and 0.09 for short and long, respectively.
1/16
For a dihybrid cross, the ratio is 9:3:3:1, and green and wrinkled is the one so doing the math, that is 1/16

I think the answer is <span>epithelial and connective tissue
Muscle cells need much energy to moves its fiber, so it must be on a highly vascularized area. The nervous system also needs a blood supply to works. In fact, the brain cells use the highest amount of energy.
Epithelial and connective tissue doesn't need much energy because its main function is to protect other tissue. It also has densely packed cells to make it sturdy.</span>
