<span>Magnetic resonance imaging is a technology that uses magnetic fields and radio waves to produce high quality 2 or 3 dimensional images of the brain structure without using radioactive tracers and ionizing radiation. The magnetic resonance intensity is proportional to the density of the protons in various tissues.</span>

Snowcat [4.5K]

Answer:

1. What modes of exercise are appropriate for this athlete?

Plyometric activity, based on a quick transition from eccentric to concentric muscle actions will help recover the power that the quadriceps are able to produce, increasing the rate of force production.

the athlete should complete weightlifting movements to overloading and improve the stretch-shortening cycle (SSC) to build impulse amplitude per step of the sprint.

2. What tests should be performed to determine the athlete's readiness for upper body plyometrics?

Successfully performing five clap push-ups in a row will be necessary to check readiness for upper body plyometric training. Upper and lower body resistance training can also be used.

3. Describe all appropriate design variables and provide the rationale for the choices.

Intensity should be gradual from low to medium-high (gradually from a 2-pound [~1 kg] medicine ball throw to a 6-pound [~3 kg] medicine ball throw);

It should be done at least two times per week; four weeks

4. What resistance training exercises may assist the athlete in reaching her goal?

Rest time in between exercises should be on a five to one work time ratio (i.e., 5:1 rest-to-work ratio).

All embryos appear female during early development. <br> a. True<br> b. False
guapka [62]

Answer:

True

Explanation:

Geneticists have discovered that all human embryos start life as females. In the early development in the embryonic stage, this is true both for humans and mammals. This changes only at the 2nd month (in the case of humans, since different mammals have different gestating periods) if the embryo can elaborate enough androgens (dominant male hormone) to offset the maternal estrogens (dominant female hormone) then, maleness develops.

If the force exerted on a sled is 100 N and the mass of the sled is 50 kg, what is the acceleration of the sled?
Anna35 [415]
<h3><u>Answer;</u></h3>

acceleration= 2 m/s²

<h3><u>Explanation;</u></h3>

From the second Newton's Law of motion the resultant force is directly proportional to the rate of change in momentum.

That is;

F = ma

Thus; F = 100 N, m = 50 kg

a = F/m

  = 100/50

  = 2 m/s²
