Air at the equator is warm and has a ______density, which creates ________ in comparison to the air at the poles.
almond37 [142]

Answer:

Lower, low pressure

Explanation:

The temperature at equator are mostly higher than at the poles almost all times of year. This high temperature causes air at the equator to warm up quickly and thus, the air density reduces and it becomes lighter. Now, light air rises upwards. Thus, creating a low pressure region at equators. This low pressure causes the air near the poles gush towards the equator.

Hence, the blanks will be filled with the words

Lower, low pressure.

In a particular species of frogs, black spots are a dominant trait and their absence is a recessive trait. In a population of fr
kipiarov [429]

The expression which is the correct way to calculate the frequency of the dominant allele is 134/200. Thus, the correct option is D.

<h3>What is Allelic frequency?</h3>

The allelic frequency may be defined as the sum total of all the alleles of a gene in a population. It represents the overall genetic diversity within a population.

The allelic frequency is calculated by the formula when the genotypes are given in number. It is as follows:

2 × Number of Purebred dominant + Number of heterozygous/ 2× Total number of individuals in a population.

∴ Allelic frequency of dominant allele = 2 × 50 + 34/ 2× 100 = 134/200 = 0.67.

The allelic frequency of the Dominant allele is 0.67 while the allelic frequency of the recessive allele is 0.33.

Therefore, it is well described above.
