The appropriate answer is the peristaltic muscle muscle contractions.
Peristalsis, involves involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract but may take place in other hollow tubes of the body, that occur in progressive wavelike contractions. Peristaltic waves occur in the esophagus, stomach, and intestines.

<span>The correct answer is peristaltic muscle contractions.
</span>  Peristaltic muscle contractions include contraction and relaxation of smooth muscles that produce a peristaltic wave, which propels the bolus (mix of food and saliva which travels down the digestive tract). Muscles contract behind the bolus to prevent it from being squeezed back into the mouth and the rhythmic contractions work to rapidly force it into the stomach.

If the release of thyroid hormone (TH) was regulated by a long-loop negative feedback, where would you find the cells that are i
pav-90 [236]

Answer:

Hypothalamus and anterior pituitary gland.

Explanation:

Lower levels of T3 and T4 in the blood or lower metabolic rate serve as signal and stimulate the release of thyrotropin-releasing hormone (TRH) from the hypothalamus. The TRH stimulates the anterior pituitary gland to release thyroid-stimulating hormone (TSH) which in turn makes the thyroid gland to release the thyroid hormones.

The elevated levels of thyroid hormones inhibit the release of TRH from the hypothalamus and that of TSH from the anterior pituitary gland.

Hence, the cells of hypothalamus and anterior pituitary gland would be inhibited by the binding of thyroid hormone to regulate the release of these hormones by a negative feedback mechanism.

• It had the body of a land animal, however, its head exhibited the distinctive long skull similar to a whale.

Knowing what we know about the link between genetics, environment and intelligence, what would be your expectations if you were
Vesnalui [34]

Answer:

I would expect them to perform similar.

Explanation:

Studies suggest that intelligence has a genetic component and can, in part, be passed from parent to child - but not only that. There are outer components that contribute to the formation of intelligent individuals. Better nutrition and more access to education would be possible explanations for the progressive increase in intelligence test scores over time.

Homozygous twins are those that are mainly characterized by similarity between individuals. These twins are formed from the same zygote, ie after the fertilization process. Because of this characteristic, they have the same genetic heritage and are therefore considered identical.

As the homozygous twins in their classroom have the same genetic heritage and attend the same environment, we can conclude that their intelligence is influenced by the same factors. For this reason, a teacher who taught these two brothers might have expectations that they would perform similarly in the classroom.
