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.

Transcription activators are different from transcription factors in that A. transcription factors prevent RNA polymerase bindin
Nesterboy [21]

Correct answer is option D.

Transcription activators accelerate transcription, while transcription factors assist RNA polymerase binding.

<h2><u></u></h2><h2><u>Explanation</u></h2>

Transcription factors are the proteins which help in proper binding of RNA polymerases in the promoter region of DNA so as to facilitate transcription.

Activators on the other hand, help in the enhancement of the transcription rate.  

Transcriptional activators are basically proteins which bind to the regulatory elements known as enhancers so as to increase the rate of transcription. Enhancers are specific DNA sequences, which may be present in the upstream or downstream region of the gene which is going to be transcribed.

It may be noted here that transcription factors are only present in eukaryotes. In prokaryotes, sigma factors are present instead of  transcription factors to facilitate proper binding of RNA polymerases on the DNA.

julia-pushkina [17]

Answer:

Image result for During which phase does a cell spend the most time?

interphase

A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Plzzzzz help ASAP
Nimfa-mama [501]

Answer:

Water is transported from one area to another area that has little water.   Water is collected and salt allowed to settle at the bottom.

Explanation:

Desalination of water is a process of the removal of salts and minerals from the water. This process is used for the production of water suitable for human consumption or irrigation.

Natural desalination occurs trough the hydrologic cycle when seawater evaporates. On the other hand, manipulated desalinization is an energy expensive alternative to natural desalination.
