Amphipathic phospholipids arrange themselves into a bilayer to form the plasma membrane
Amphipathic refers to holding property of both water affinity and it's phobia. Thus, amphipathic compound will have structure suitable for both. Same is the condition with lipids. Lipids have hydrophobic tail that are made up of fatty acids. They also have hydrophilic head which is phosphate group. It is polar in nature and hence easily interacts with water.
The two layers of lipid come together to form plasma membrane. Here, the hydrophilic head remains outside while the hydrophilic tails remain inside the bilayer. Both phosphate and fatty acids are attached to glycerol. Other carbohydrates may attach to lipids forming glycolipids, which play different significant roles in functioning of cell.

This reduction in starch content occurred because starch was changed into simple sugars
<h3>Explanation:
</h3>
Starch is a polymeric carbohydrate consist of many glucose units linked by glycosidic bonds. The iodine test is used to test for the presence of starch. Starch will change color to an intense "blue-black" colour after the addition of aqueous solutions of the triiodide anion. To do it we can add Iodine-KI reagent to a solution or directly on a potato or other materials such as bread, crackers, or flour The reaction between amylose that present in lesser amounts and iodine is said to account for the intense color change seen.
An iodine test of a tomato plant leaf revealed that starch was present at 5:00 p.m. on a sunny afternoon in July. When a similar leaf from the same tomato plant was tested with iodine at 6:00 am the next morning, the test indicates that less starch was present in this leaf than in the leaf tested the day before. This reduction in starch content occurred because starch was
- 1. changed directly into proteins
- 2. transported out of the leaves through the guard cells
- 3. transported downward toward the roots through tubes
- 4. changed into simple sugars

Answer:
Sperm motility
Explanation:
Sperm motility is the property of the sperms to move properly through the woman's reproductive system during the process of fecundation. The sperms need to move into the female reproductive tract to fertilize the ovum and thus form the egg cell.
Answer:
Explanation:
The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer. The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high
