A survey reveals that 25 percent of a population of 1,000 individuals have attached earlobes (are homozygous recessive for the t
Mumz [18]

Answer:

d. pxp +2pq

Explanation:

The formula for genotype frequency for a population in Hardy-Weinburg equilibrium is as under:

                           p² + 2pq + q² = 1

where, p = dominant allele

           q = recessive allele

Here,

 p² represents frequency of homozygous dominant genotype

2pq represents frequency of heterozygous genotype

q² represents frequency of homozygous recessive genotype

Also, although the genotypes p² & 2pq are different from each other yet phenotypically they both will collectively produce dominant trait i.e. free ear lobes not attached earlobes. So the term "p² + 2pq or pxp + 2pq" represents the frequency of the individuals who show the dominant phenotype in this particular population. Dominant phenotype will comprise 75% of the population.

AysviL [449]

The student put under the "physical changes" portion of the poster about aluminum is option "B".

<h3>What is the boiling point and melting point of aluminum?</h3>

The melting point of aluminum is 933.47 Kelvin, 660.32 degrees Celsius, or 1220.58 degrees Fahrenheit.

It's normal boiling point is 2792 Kelvin, 2579 degrees Celsius, or 4566 degrees Fahrenheit.

Thus, Options "B" aluminum met at 660 degree celcius.
