Answer:
A., Vision. Eyes contain two types of photoreceptors called rods and cones.
Answer:
500
Explanation:
According to the given information, the total number of albino people in the population= 1000/4 = 250.
Since albinism is an autosomal recessive trait, the genotype of albino people would be homozygous recessive. Therefore, the frequency of homozygous recessive genotype in the population (q2) = 250/1000= 0.25.
The frequency of recessive allele (q) = square root of 0.25 = 0.5
Since p+q=1. So, p (frequency of dominant allele) = 1-q = 1-0.5 = 0.5
Frequency of heterozygotes in the population= 2pq = 2 x 0.5 x 0.5 = 0.5 or 50%
Therefore, expected number of heterozygotes in the given population= 50% of 1000 = 500
Answer:
Contraction is prevented
Explanation:
The sarcomere is the basic contratile unit of muscle i.e the unit responsible for contraction in the muscle and it consist of two main protein actin; which forms filaments involved in contraction and myosin; a motor protein responsible for contraction. Calcium interacts with these protein and in the absence of Ca, contraction is inhibited (sacromere with not be able to undergo contraction)
It would better your city. The city would look way nicer and a lot of people would probably enjoy a recycling program. For the reasons of having reused items so the dump won't be as bad and it would give more jobs and be a healthy way of discarding old paper and bottles. It could easily help out your city. The recycling program would be a great idea and I hope it could happen.
I hope this is what you wanted.....
