Magine that a researcher is studying the color of grasshopper exoskeletons. Assume that this phenotype is caused by the action o

f two alleles. Green grasshoppers have the genotype AA and brown grasshoppers have the genotype aa. If the frequency of the A allele in this population is 0.2, what is the frequency of the a allele?

Answer:

0.8

Explanation:

Allele frequency simply shows how common an allele is in a population.

It is calculated by counting the number of times it appears divided by the total number of copies of the gene.

The frequency of all alleles  of a gene present in a population must equate to 1.

so,<u><em> p+q=1</em></u>

If the Allele frequency of A  whose phenotype are green grasshoppers is  0.2 to find the frequency for a (brown grasshoppers) will be';

<u><em> 1-0.2=0.8</em></u>

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.

Alveoli, capillaries, and glomeruli capsules are all lined with simple squamous epithelium. What function is shared by these str
baherus [9]

The common function shared by alveoli, capillaries and glomerular capsules are lined with simple squamous epithelium so they are all involved where absorption  or transport of the materials occur.  The function of the squamous epithelium is mainly selective transmembrane transportation either by using the concentration gradient or by active transport by using the membrane bound carrier proteins.

The pulmonary alveoli are highly vascular in structure and are formed by a layer of the squamous epithelial cells and a network of capillaries.

The capillaries are also made up of squamous epithelial cells and gas exchange between the alveoli and blood vessels occurs through these capillaries.
