Answer:
sexual selection
natural selection
Explanation:
Natural selection is an evolutionary mechanism (changes the allele frequency) by favouring traits that are advantageous among others because they increase the survival and reproduction. In the example above, mosquitofish that live in the predator-rich ponds devoloped a trait that help them survive (swimming in short, fast bursts). This adaptation to environment is favourable by natural selection.
Sexual selection refers to the female mosquitofish and the fact that they choose their males (with better reproductive success).
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

mark me brainliest please
<span>Parenteral Feeding is high in Dextrose which is a form of sugar. The Carbohydrate breakdown of the feeding is what raises the client's serum glucose. The client is also more than likely to be a Diabetic as the body's natural insulin should have broken down the Carbohydrate after six hours.</span>
Protiens are very important and they are regarded beneficial
The protiens and peptides differ in their size protiens are relatively small
There are soi many difference among both because
<span>Several amino acid sequences are possible for proteins and peptides
</span>As there are 20 amino acids and different folding structure
so correct option is A
hope it helps
