Which digestive hormone is secreted when fats and carbohydrates, especially glucose, enter the small intestine?.
blsea [12.9K]

Gastric inhibitory peptide (GIP) a digestive hormone is secreted when fats and carbohydrates, especially glucose, enter the small intestine.

  • A member of the secretin family of hormones, glucose-dependent insulinotropic polypeptide is an inhibitory hormone.
  • It is sometimes referred to as gastric inhibitory polypeptide or stomach inhibitory peptide.
  • The enteroendocrine K-cells, which are widespread in the small intestine secrete GIP.
  • The hormone gastric inhibitory polypeptide, which is released by intestinal mucosal cells, prevents the stomach from producing hydrochloric acid.
  • Additionally, it improves the islets of Langerhans' beta cells' ability to secrete insulin, which results in a considerable increase in blood insulin concentrations following oral glucose delivery.

Hi, I'm stuck on these questions. Thanks in advance :) 1a. If an ovum is released by the ovary but is NOT swept into the infundi
MA_775_DIABLO [31]

Answer:

If the ovary does not enter the fallopian tube, it falls into the abdominal cavity and cannot be fertilized unless it finds it's way back to the uterus. Ectopic or tubular pregnancy would cause the fallopian tube to swell and eventually rupture.

Explanation:

When ovaries are released by the oviduct, it enters the fallopian tube, fertilizes and moves to the uterus where it is implanted. But if the ovum does not enter the fallopian tube, which could be as a result of an abnormality or the fallopian tube removed to prevent pregnancy or for medical reasons, then the ovum enters the abdominal cavity.

Pregnancy is still possible in this case if the ovum finds its way back to the uterus or IVF is been administered to the patient to induce pregnancy.

Ectopic or tubular pregnancy occurs when a fertilized egg is implanted in the fallopian tube. This is sometimes the case in the early weeks of pregnancy but eventually moves to the uterus. In severe cases, it would remain in the tube which in turn would make the tube swell and rupture.

How will you prove that the food stored in leaves os starch​
sladkih [1.3K]

Answer:

To prove the food stored in leaves is starch "we will use a iodine indicator, if the leaf turn blue-black then it is confirmed that the leaf has starch. "

Explanation:

To prove the stored food in leaves is starch, first we will take a leaf, then we will treat the leaf in hot water followed by alcohol. The leaf will die when comes in contact with hot water and the alcohol will help us in the break down of the chlorophyll. Which will fade the green color. Now, we will put iodine, which we use as an indicator in the leaf, when it turn blue-black, it is confirmed that starch is present in the leaf. Sometimes the leaf will turn reddish brown, which depicts the absence of starch.
