The correct answer is option C

The stage of evolution represented by the middle finger must be imbibed by the letter ‘M’ in its name which depicts the “mutation”. In mutation a new gene is added to produce variation in the frequency. The other fingers depict the following stage of evolution:

a) Pointer finger depict the evolution caused by the movement of an individual or species into or out of the area. This finger represents gene flow.

b) The small finger represents the shrinking of population and thus represents the change in gene flow due to any mishappening or epidemic or calamity. This finger represent the small population

c) The ring finger represents the evolution caused by mating/sexual intercourse. This finger represent non random mating

d) The thumb represents the natural selection through adaption.

5. Many sciences rely on observation instead of (or in addition to) designed experiments. Compare the data quality issues involv

fredd [130]

Answer and Explanation:

The quality of the data can be higher in observational or experimental studies depending on the subject being researched.

In a way, we can think that experimental studies have better data quality, due to the design of the experiment and the control of the study groups and the variables that are not possible to be established in the obsevational experiments.

However, in the case of studies of abstract subjects, the experimental study ceases to provide high quality activities, and it is necessary to establish an observational study so that efficient data can be promoted.

Her immune system is exhibiting the _ line of defense. This defense is part of _ immunity.

lisov135 [29]

last line of defense is the first part.

and the defense is part of her system immunity. this makes sense since the immune system is used to guard against viruses and diseases

In humans, the DMD gene is required for proper muscle function. Mutations in the DMD gene display X-linked recessive inheritance

ANEK [815]

Answer:

Explanation:

As the inheritance is X-linked,recesson so for expression of muscular dystrophy in any given muscle,

$\frac{enh1- enh2+ enh3 - DMD+ }{enh1- enh2+ enh3 + DMD+}$

enh1+ /enh1 + = Shows muscular dystrophy in heart (Homozygous for -)

enh2+/enh2+ = Shows no muscular dystrophy in arms (Homozygous for +)

enh3-/enh3+ = variabl or mosaic for muscular dystrophy in leg muscles (Hetrozygous for enh3)

1. how many chambers does the human heart have?

cluponka [151]

<h2>Answer:</h2><h3>1. four</h3>

Your heart has four separate chambers that pump blood, two on the right side and two on the left.

2. When the ventricle relaxes, the aortic valve closes to prevent blood from flowing back into the ventricle. When the aortic valve is not working properly, it can interfere with blood flow and cause the heart to strain to send blood to the rest of the body.

3. In medicine, a person's pulse is a pressure wave caused by the expansion of the arteries as a result of the circulation of blood pumped by the heart.

4. Capillaries are tiny vessels that branch out from arterioles to form networks around body cells.

Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them.

hope this help! ^^
