Answer:
Use 400 x in order to study the structure clearly.
Explanation:
Cell structures could be clearly identified when magnify the microscope about 400 x by using a compound microscope. Due to high magnification power of compound microscope, the individual is able to see different structures that are present in cells. while by using lower magnification, the individual is unable to see different structures clearly. So use high magnification in order to study the cell.
Answer:
D) When corals are babies floating in the plankton, fish swim with them and protect them from harm.
Explanation:
This is the statement that does not explain how fish and coral relate to one another. It is false that when corals are babies, fish swim with them and protect them. However, the rest of the statements are true. It is true that fish eat predators, and that they also eat seaweed and kelp that could smother the coral. Finally, it is also true that some fish live symbiotically with coral, luring prey for the coral to kill and eat.
Answer:
The correct answer is D. maintain membrane fluidity through its disruption of fatty acid packing.
Explanation:
<u>Cholesterol</u> is a steroid lipid and is a constituent of biological membranes. It regulates the <em>fluidity</em> of the membrane (so, option C is not correct). Since cell membranes are composed of another type of lipids, the phospholipids, which form a bilayer, cholesterol distributes between the phospholipid tails and avoids these molecules pack each other forming rigid clusters. Thus, the option which better explains the effect is <em>D. maintain membrane fluidity through its disruption of fatty acid packing.</em>
