Answer:
<em>The correct option is D) .45</em>
Explanation:
The results can be deduced by using the HARDY-WEINBERG LAW.
49% (Since blue is recessive, and the frequency of blue eyes in a population = q squared = .20, the frequency of the blue allele is the square root of q squared = the square root of .20 = .45. Therefore, p, the frequency of the brown allele is 1.0 - .45 = .55. The frequency of the heterozygous population is 2pq = 2 X .45 X .55 which is equal to .49.
Answer:
yes A system can be also be a system
The answer is C.
It is the site of gas exchange in the lungs.
Gas exchange occurs only in alveoli. Alveoli are made of thin-walled parenchymal cells, typically one-cell thick, that look like tiny bubbles within the sacs. Alveoli are in direct contact with capillaries (one-cell thick) of the circulatory system.
