In a sample population of people, 36% have the recessive trait of "free" earlobes (q2). What is the frequency of the dominant al
ICE Princess25 [194]

Answer:

Explanation

Given that 36% are recessive in traits

100-36 = 64% for dominant traits considering a whole population to be 100%

P=dominant allele

q= recessive allele

P2= dominant genotype

q2= recessive genotype

according to hardyweinberg principle, p+q=1

64/100= 0.64 frequency for dominant traits or genotype, therefore

p2=0.64

then

P=√0.64

p= 0.8

Therefore, dominant allele frequency (p) for the population is 0.8

krek1111 [17]

Answer:

A. motor neurons; peripheral nervous system

Explanation:

Motor neurons carry signals from the peripheral nervous system to the muscles. This causes the muscles to either relax or contract. Note that the peripheral nervous system consists of neurons and parts of neurons outside of the central nervous system which consists of the brain and spinal cord. When signals are transmitted between the motor neurons and peripheral nervous system, this causes a response to stimulus in the muscles which would either, relax or contract.

TiliK225 [7]
<h3>Answer:</h3>

Jean has a sample of a liquid. If she changes the liquid's phase by <u>Evaporating</u> it, the molecules will spread out, allowing the sample to expand and fill a container of any shape or volume.

<h3>Explanation:</h3>

Evaporation is a kind of condensation that happens on the surface of a liquid as it turns into the gas state before approaching its boiling point. The enclosing gas must not be immersed with the evaporating matter. Evaporation is a major element of the water cycle and is continually happening throughout the environment.
