Answer:

In the exercise-depression study by Blumenthal et al. (the SMILE study), which of the treatments had the best success when considering the percentage of individuals who had either recovered or at least partially recovered at a 6-month follow-up period? B. Exercise group.

Explanation:

Exercise has different depression-reducing effects. It enables the body to producte endorphins that reduce sensations of pain. Moreover, it changes the neurotransmitter levels associated with depression (for example, norepinephrine) and it developes a sense of mastery and self-control through regular practice. The SMILE study concludes that aerobic exercise on MDD remission extend the benefits and it might be better than the benefits of antidepressant use.

If a population with two alleles is at Hardy-Weinberg equilibrium ad the frequency of one allele is 0.7, what is the heterozygot

Vinil7 [7]

Answer:

B. 0.42

Explanation:

Since the two alleles are at Hardy-Weinberg equilibrium, the sum of the frequency of two alleles will be one. If the frequency of a dominant allele is "p" and that of the recessive allele is "q", then p+q=1

According to the given information, the frequency of one allele in the population is= 0.7

This means that the frequency of the other allele would be= 1-0.7 = 0.3

Frequency of heterozygote in the population =2pq = 2 x 0.7 x 0.3 = 0.42

The anterior portion of the body of most annelids, such as the earthworm, is adapted for sensing the environment.

Diano4ka-milaya [45]

Answer:

The answer is False. Although sensitive cells are more abundant in the anterior portion of the annelid´s body, in general, they are arranged in all the segments.

Explanation:

Annelids, such as the earthworm, have a variety of sensory cells:

Mechanoreceptors, disposed of in groups in each segment of their body.

Photoreceptors: Light-sensitive cells. Although they are located in the whole body, they are abundant in anterior and posterior segments, concentrated in the intern and dorsal part of the epidermis.

Humidity receptors are the most sensitive cells and are located in the first segments of the earthworm body

Chemoreceptors: sensorial cells cumulus forming a prominent tubercle with prolongations that extends through the cuticle. These tubercles form three rings in each segment but are especially abundant in the anterior part of the body.

The tegument is very rich in free nervous terminations, which functions might be tactile.
