<h3> Chemical level is the simplest level of organization in a human being. </h3>
Answer: B. 0.77
Explanation:
We should note that from the Hardy-Weinberg law, the formula used is:
p²+ 2pq+ q² = 1
From the information given,
p = purple allele
q = red allele
q² = 59/100 = 0.59
Then, the frequency of the red allele that is recessive will be:
q² = 0.59
q= √0.59
q = 0.768.
q = 0.77
Therefore, the correct option is B.
During the lunar month, the Moon goes through all its phases. You can see the phases drawn in the image below. Just like the Earth, half of the Moon is lit by the Sun while the other half is in darkness. The phases we see result from the angle the Moon makes with the Sun as viewed from Earth.

Planarias are flat worms that live freely in freshwater and sometimes in teh logs, soil, plants, or other dump or humid areas. They are from the class of Turbellarians. They have a very good ability in regeneration. They are acoelomerate which means that their body is very solid without any hollows.
They excrete unwanted objects from their body using their excretory system which is consists of series of tubes with length similar to their body length. The flame cells remove excess water through the use of the cilia and pass them to the ducts. At the end of the duct, there exist pores called the nephridiapores.
