Why are glial cells referred to as the "forgotten brain cells?" state five ways that glia differ from neurons. what would happen
yaroslaw [1]
1. Glial cells are refereed to as forgotten cells because the number of scientific research carried out on glial cells is very small compared to the other nerve cells. The other nerve cells in the nervous system have been focus of research for years, this is done in order to better understand human brain; but the glial cells have not receive that same kind of attention from researchers.

2. The following differences exist between neurons ans glial cells:
a. Glia cells has only one process while neurons have two processes, which are axon and dendrites.
b. Glial cells can not generate action potentials while neurons can.
c. Neuron have resting potential; glia cells do not.
d. Neurons possess chemical synapses which use neurotransmitters. Glial cells do not possess chemical synapses.
e. The glial cells in the nervous system are much more in number than the neurons.

3. If the glial cells stop functioning in a human being, the entire nervous system will start to malfunctioning. This is because the roles that the glial cells play in the nervous system are very important ones that are very necessary for the overall functioning of the nervous system.

Consider a population of 425 diploid giant Sequoia trees. In this population, you observe the following genotypic counts: 100 ho
Lemur [1.5K]

Answer:

q = 0.42

Explanation:

This question is an example of Hardy-Weinberg question and there are two equations necessary to carry out this question;

p + q = 1

p² + 2pq + q²  = 1

where;

p = the frequency of the dominant allele

q =  the frequency of the recessive allele

p² = the frequency of individuals with homozygous dominant genotype

2pq  = the frequency of individuals with heterozygous genotype

q² = frequency of individuals with the homozygous recessive genotype

Since the total  population = 425

q² = \frac{individuals with recessive genotype}{Total Population}

= \frac{75}{425}

q² = 0.1765            

To find q; we need to square root both side to           eliminate the square from  q².

∴ \sqrt{q^2}=\sqrt{0.1765}

q = 0.4201

q = 0.42       (to two decimal places)
