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)

posledela

Answer:

The correct answer is 1. EEG.

EEG or electroencephalography is a technique used to measure the electrical activity of the brain.

8 to 16 pairs of electrodes are placed on the scalp which record the electrical activity or impulses (in volts) generated by thousands of neurons or nerve cells present in the brain.

It provides the real-time imaging of the electrical activity of the brain.

The recorded impulses are first sent to the amplifier as the magnitude of the brain's electrical impulses is very low.

The amplifier then amplifies the results and show it on the screen in the form of voltage units.
