levacccp [35]

Answer: Hypothalamus

The brain coordinates the physical changes that occur during puberty and the hypothalamus plays an especially important role in this process.

Explanation:

Since the hypothalamus controls the secretion of hormones from the pituitary gland, and the pituitary gland, also known as master gland, controls the activities of all other glands like the following:

- gonads (ovaries and testes), responsible for producing many of the sex hormones and hence, development of sexual characterictics

- thyroid, responsible for producing thyroxine, responsible for body metabolism and development.

Thus, hypothalamus plays important role in puberty

AVprozaik [17]

Answer:

In Labrador dogs, black coat is dominant to chocolate, normal vision is dominant to progressive retinal atrophy (PRA), and normal hip joint is dominant to hip dysplasia. All these genes assort independently. Two dogs that are heterozygous for alleles of all three genes are crossed. Using rules of probability (not a Punnett square), what is the chance that the first pup born to these dogs will be chocolate, have normal vision, and have normal hip joints?

BbVvHh x BbVvHh= BBVVHH, BbVvHh, BbVvHh, bbvvhh

Bb= black coat dominant

Vv= Normal vision dominant

Hh= Normal hip join dominant

probability of having a first born of these dogs will be chocolate, have normal vision and have normal hip joint is 0

Explanation:

As the punette square gives 3:1 phenotype having three black coat, normal vision and normal hip joint and one chocolate, progressive retina altropy and hip dysplasia

Read the passage. What is the claim?
malfutka [58]

Answer:

<em>Hello There. the Correct answer to this is This drug helps people lose more weight than diet and exercise alone. The reason for this statement is that with diet and exercise alone, 23% lost weight whereas with diet, exercise and the drug, 48% lost weight so the conclusion is that the drug enhanced weight loss. As a personal comment, the trouble with synthetic drugs is that there are usually side effects so that avoiding the drugs also avoids side effects so therefore I think it is best to find the right diet and exercise that actually lowers weight or take a vitamin or herb supplement to help with this. </em>

Hope it helps!
