The correct answer is B since the organism is just copying itself.
<h3><u>Answer;</u></h3>
The polysaccharide is <u><em>Hyaluronic acid</em></u>
<h3><u>Explanation;</u></h3>
- <u><em>Hyaluronic acid is a natural polysaccharide</em></u> which is in the class of glycosaminoglycans that is mostly found in <em><u>neural, connective and epithelial tissues in human body. </u></em>
- <em><u>Hyaluronic acid is made up repeating units of glucuronic acid and N-acetylglucosamine</u></em> that are<em><u> joined by alternating β- 1,4 and β- 1,3 glycosidic bonds. </u></em>
- It is a <em><u>linear polysaccharide and is the only glycosaminoglycan </u></em>that lacks sulfate atoms in its structure.
Answer:
Following are the methods used by plants to encourage cross-pollination.
1) Wind: Wind is the agent through which pollen grains of the flower flew in the air and falls on the stigma of another flower.
2) Bees: Bees are also called pollinators because they help in the transfer of pollens from one flower to another flower and causes cross pollination.
3) Water: There are some plants in which cross pollination occurs through water. Pollens drop into the water and transported to another flower through water flow.
The answer to the question above is this: <span>the endothelium of CNS capillaries forms a blood-brain barrier. The blood-brain barrier is actually a mechanism that the capillaries that carry blood to the central nervous system can do. What this barrier does is that it filters and only allows certain substances (and not all), that's why this cannot directly affect the neurons in the central nervous system.</span>
