Answer:
65536 cells
Explanation:
starting from 1 cell at zero minutes there will be 1 (2^0) cell; 2^0 = 1
after 15 minutes there will be 2 (2^1) cells
after another 15 minutes ( 30 min) there will be 4 ( 2²) cells
after another 15 minutes ( 45 min) there will be 8 (2³) cells
after n number of 15 minutes there will be (2^n) cells
calculate number of 15 minutes in 4 hours
4 hours = 4 × 60 minutes
number ( n) of 15 minutes in 4 hours = (4 × 60 minutes) / 15 minute = 16
using the formula above and substitute 16 for n in the formula
Number of cells = 2 ^n = 2^16 = 65536 cells
The fibrous proteins which are found in connective tissues of the animals are either collagen, elastic, or reticular fibers. This collagen fibers provide strengths to the connective tissues.

The food molecules that are absorbed from the small intestine lumen into the lacteal, the lymphatic capillary located within the villus would be the lipids. Most of the dietary lipids are neutral fat or the so-called triglyceride. These are composed of a glycerol backbone wherein each carbon is linked to a fatty acid. In the small intestine, the villi, microvilli and plicae circulares functions to increase the surface ares that is available for the absorption of the nutrients. Each of the villus consists of a network of capillaries and lymphatic vessels which are called the lacteals which is responsible for the absorption of lipids.
