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.
The correct answer is 50%, or 1/2. We know that round seeds are dominant, since the round pea plant has a genotype of Rr and the wrinkled pea plant has a genotype of rr. If it helps, draw a Punnett square with the two genotypes.
R r
r
r
The square works exactly like a coordinate grid. Combine the letters above and beside whichever of the four spaces you chose to find the genotype for that space.
R r
r Rr rr
r Rr rr
Therefore, 2 out of 4 of the pea plants have round seeds, since a genotype of Rr means that a plant will have round seeds, and 2 out of 4 will have wrinkled seeds, since a genotype of rr means that a plant will have wrinkled seeds. 2/4 simplifies to 1/2, or 50%. Therefore, there is a 50% chance that the offspring will have wrinkled seeds.
Hope this helps!
Answer:
Gas exchange during respiration occurs primarily through diffusion. Gas molecules move from a region of high concentration to a region of low concentration. Blood that is low in oxygen concentration and high in carbon dioxide concentration undergoes gas exchange with air in the lungs.

Answer:
d
Explanation:
sugars are also known as glucose and the formula for photosynthesis is water+carbon dioxide=oxygen+glucose
