The answer choice above which best describes how the cell cycle relates to neurons is:
Neurons do not go through M phase.
Option a is the correct answer
<h3>What is a neuron?</h3>
A neuron is defined as structural and functional unit of the nervous system
Complete question:
In humans, adult brain cells called neurons are terminally differentiated. This means that they are completely mature and no longer undergo the cell cycle.
Which of the following statements best describes how the cell cycle relates to neurons?
a. Neurons do not go through M phase.
b. Neurons passes through the M phase
c. None of the above
So therefore, the answer choice above which best describes how the cell cycle relates to neurons is:
Neurons do not go through M phase.

Answer: Tissue
Explanation:
Tissue is a group of similar cells that work together to serve a common function. Tissues that work together are grouped and called organs which futher makes up a system. The digestive system for instance is made of different organs such as intestine, stomach which works together to digest food.
Each digestive organ in the digestive system has its own unique tissues, with each tissue having its own unique cells.

Answer:
The frequency of recessive allele should be 0.30.
Explanation:
According to Hardy-Weinberg equilibrium, sum of both dominant allele frequency (p) and recessive allele frequency (q) should be equal to 1 (p+q = 1).
Brown hair = dominant (p)
white hair = recessive (q)
49% mice are brown hair
so dominant genotype frequency = 0.49
According to Hardy-Weinberg principle, square root of the genotype (homozygous) is equal to allele frequency.
√p =√0.49 = 0.70
The dominant allele frequency is 0.7
Now, by this value we can find the recessive allele frequency by
p + q = 1
1 - 0.7 = 0.3
So, the recessive allele (white hair mice) frequency is 0.30.
Down syndrome causes a distinct facial appearance, intellectual disability, developmental delays, and may be associated with thyroid or heart disease.
