Microvilli which line down the luminal surface of those epithelial cells represent the resorptive function of the proximal tubule.
<span>The high quantity of mitochondria inside the epithelial cells of the proximal convoluted tubule is needed in order to supply the energy for the active transport of sodium ions (to enter the cell from the luminal side).</span>
Answer:
Genetic engineering has multiple applications in different fields. Genetic engineering is the process by which alterations are made at the genetic level so that the final product is superior in quality and yield.
Explanation:
Following are few of it's applications:
<u>Medical field</u>- Genetic engineering is been used to produce insulin artificially, human growth hormones, anti hemophiliac factors, vaccines and other drugs.
<u>Agricultural industry</u>- It has been used to synthesize improvised crops which give better yield and are pest resistant. E.g Flavr savr, a species of tomato which is more juicy and larger in size than regular tomatoes.
<u>Environment</u>- With the introduction of herbicide resistant corn, farmers reduced the use of tractors which in turn reduced the amount of greenhouse gases. Also, by imparting disease resistance to plants, a lot of plants are prevented from dying. In addition, the biodiversity of an area can be maintained.
