Answer:
Frequency of the B3 allele 
Explanation:
The allele frequencies in a given population remain constant which means that every generation will have the same gene pool across the generations. As per Hardy Weinberg’s first equilibrium equation, the sum of frequency of all the alleles at a given locus is equal to one
Thus, if "p" represents the frequency of B1 allele and "q" represents the frequency of B2 allele and "r" represents the allele for B3 allele. Then, sum or "p", "q" and "r" is equal to one.

Substituting the given values, we get -

Answer:
Central and Peripheral
Explanation:
The nervous system is divided into two parts: the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord.
On the other hand the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs. Each part of the system plays a vital role in how information is communicated throughout the body.
The below diagram provides a schematic view of the role of each sub-division of the Nervous System.
<span>Connective tissue supports the framework of the liver, and epithelial tissue protects the liver.
Connective tissue holds the liver in place during movement, and epithelial tissue forms the lining of the liver.
Connective tissues are mainly used in forming support networks within tissues and Epithelial tissue tend to line the organs and form protective cell layers.</span>
Answer:
B) cAMP
Explanation:
Phosphodiesterase is an enzyme that breaks a phosphodiester bond, for example in molecules such as cAMP and cGMP. So, phosphodiestarases are are regulators of signal transduction: regulate the duration of signaling pathway.
Caffeine is central-nervous-system stimulant and the mechanisms of its action usually are: mobilization of intracellular calcium or inhibition of specific phosphodiesterases.
Below are the choices that can be found elsewhere:

<span>An outlier is a result that is abnormally too high or too low. Most of the results fall between 66 and 70, but 78 seems to be abnormal, so it's your outlier. The answer is D. Hope it helps :)</span>
