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.

Secondly it is thoracic: chest cavity

And thirdly it is pleural cavities: which consist of ths lung cavity

That is it will encounter tbe parietal layer of the serous membrane first :lines cavity

Explanation:

The organs in the body are safely guarded by the membrane, cavities and sheaths(which has different compartment). They act to protect the organs in the body like lungs.

A person who was shot with a gun, the bullet must pass the body cavities when moving to the lungs. It must first pass through the 3 cavities before it arrives at the lungs that is the ventral cavity, thoracic cavity and the pleural cavity. The serous membrane is usually found within the walls of the thoracic cavity.
