<u>proximate hypothesis</u>

<u></u>

What is a proximate hypothesis?

An event that is nearest to, or directly accountable for, creating some observed effect is referred to as a proximate cause. This contrasts with a higher-level ultimate cause (also known as a distal cause), which is typically regarded as the "real" cause of an event.

 Ex: What caused the ship to sink? A breach beneath the waterline allowed water to enter the hull, making the ship denser than the water that was supporting it, which prevented it from remaining afloat. The ship's collision with a rock, which tore a hole in its hull, was the ultimate reason.

Which of the following is NOT true about the absorption of fats?
babunello [35]

Answer:

The best choice from the answer options for the question: Which of the following is NOT true about absorption of fats, would be: C: The chylomicrons enter the blood in the villi capillaries.

Explanation:

Because of the characteristics of fatty acids, and fats in general, they are not able to either pass the intestinal enterocytes, and enter the bloodstream, as easily as glucose, or other molecules, can. Instead, they first must be passed into the enterocytes, the intenstines´ cells, by their combination with bile. Once inside the intestine, the enterocytes take up the fats and combines them with lipoproteins and cholesterol in order to create the chylomicrons. But before these chylomicrons can make their way to the blood, first they must be taken up by the lymphatic vessels present in the villus of the intestinal epithelium, not the blood capillaries. It will be the lymphatic system which will be reponsible for passing the fats to the bloodstream, who will then distribute them to the appropriate cells in the body as energy is required. Or they will be taken for storage by the liver.

Of all the water on the earth, only about 3% is fresh water. 68% of all the freshwater is frozen as glaciers and is unavailable
AleksAgata [21]

Answer:

The correct answer is statement A.

Explanation:

The procedure of purifying ocean water, that is, the saline water so that it can become suitable for drinking is termed as desalination. Almost 70 percent of the Earth is covered with water and of this only 3 percent is used for drinking purposes. On a huge scale, the process of desalination would require the boiling of water, which would eventually require an enormous amount of energy.  

Reverse osmosis and electro-dialysis are the methods used for desalination. However, these procedures are very costly and cannot be performed on a huge level as it can affect the economy of various countries.
