Answer:
Microvilli are lined with blood vessels as well as lymphatic vessels.
Explanation:
The small intestine is one of the most important part of the body. This is the main site of digestion and absorption of food in the body. The three main parts of small intestine - dedenum, jejenum and ileum.
The small intestine has both villi and microvilli in its structure. These villi helps in increase in the surface area for absorption. Microvilli are lined with the blood vessels only and not with the lymphatic vessel. This vessels are directly connected to the hepatic portal system.
Thus, the correct answer is option (C).
Active transport is the movement of molecules against the concentration gradient from an area of high concentration to an area of low concentration, which requires energy in the form of ATP. Hope this helps! ^.^
Answer:
They used radioactive labeling techniques to build two different types of phage.
Explanation:
In 1952, a set of experiments were carried out by American biochemists Alfred D. Hershey (1908-1997) and Martha Chase. They prepared two separate virus samples, one contained DNA labeled with a radioactive isotope and the other contained protein labeled with a different radioactive isotope. They grew the two types of viruses separately, infected bacteria with the two sets of phages and analyzed the bacteria for radioactivity. From the results obtained, Hershey and Chase concluded that the viral genetic material was DNA and not protein, reinforcing the observations previously made by Avery.
