Answer: controls milk production release

Explanation:

Oxytocin is a cyclic peptide containing 9 amino acid residues. In its molecule, we find several amide groups (-CONH), which were formed through peptide bonds between amino acids. It is produced in the paraventricular nuclei of the hypothalamus by the magnocellular neurons but is released only in the neurohypophysis. Oxytocin is a fundamental importance in birth labor and the ejection of milk. Oxytocin acts on labor by stimulating uterine contractions, as well as dilating the vaginal canal and distancing the pubic symphysis. The suction promoted by the babies in the halo of the mother's breast also promotes the release of oxytocin, whose function is to help in the secretion of milk.

Answer:

B) Absence of native grasses

Explanation:

The grasses, which acted as a windbreak and whose roots anchored the soil in place, were overgrazed and/or removed to allow for farming. Once a few years of severe drought affected the area, any wind storm was able to blow the topsoil away, rendering the farm land of the Great Plains virtually unusable in many areas. Ground cover is an essential part of sustainable agriculture.

Which process is a squeezing motion of the circular layer of smooth muscle in the small intestine?
Over [174]

Segmentation is a squeezing motion of the circular layer of smooth muscle in the small intestine.

<h3>What is segmentation in the small intestine?</h3>

Segmentation, which mostly affects the small intestine, is made up of localized contractions of the Gastro-Intestinal tract's circular muscle. These contractions separate out little portions of the intestine, allowing their contents to move back and forth while being continuously divided, broken up, and mixed.

Our intestines' circular muscles contract during segmentation to churn food back and forth, rather like a washing machine. This churning helps break down food into tiny bits for digestion by allowing it to mix with gastric secretions in the intestines. By bringing chyme into contact with the intestinal walls during segmentation, the technique also helps to increase absorption.

serg [7]

When Charles Darwin considered wings of birds, apart from his famous proposal he also predicted that fossils will be found with structures that are intermediate between early and modern form.

Answer: Option C

<u>Explanation:</u>

Charles Darwin was basically referring to transitional Fossil while considering Wings of bird. So what are transitional fossil? They are the fossil remains of both the ancestral group and the descendant group.  

Since we don’t have enough record of the fossils, it is very difficult to know the accuracy of transitional fossil.  However, we do have some record of fossils from which we can gather enough evidence of how the fossils where earlier and how it evolved over a period of time.

Kryger [21]

Answer:

a. People with celiac disease should include foods with dietary fiber such as beans, fruits, vegetables, brown rice, and quinoa.

e. Home-cooked meals are a good way to increase variety and reduce the cost of a gluten-free diet.

Explanation:

Celiac disease is an autoimmune disease, as stated above. This disease causes the defense cells of an organism to attack the stomach cells causing an inflammation that is extended and stimulated by the glutem. As a result, the individual has diarrhea, constipation, weight loss, anemia, a feeling of fullness, colic, abdominal discomfort, severe pain and may even develop ulcers and cancers.

Glutem is a protein found in wheat, barley and rye and for that reason, individuals with this disease should avoid these foods or foods derived from them. This type of diet should accompany the sick person for life and they should be encouraged to eat homemade foods that know the origin and composition. In addition, it is necessary that these people feed on dietary fibers, such as beans, fruits, vegetables, brown rice and quinoa.
