Answer:
Lysosome
Explanation:
The lysosome is surrounded by a single membrane. This membrane made up of lipoproteins. The lysosome is also known as a suicidal bag. This is meant for the digestion of injured cells. The acidic enzymes present in it helps in cell lysis. The cytoplasm burst due to osmotic swelling. If a single lysosome will burst in the cell it won't affect the cell. When several lysosome bursts together it can rupture other cellular organelles. It is fatal for a cell.

Answer:
C) commensalism
Explanation:
Commensalism is an interaction in which one organism benefits without causing any harm to the other. The other organism derives no benefit from the relationship.
The scenario above in which the dwarf mistletoe obtains nutrients from the vascular tissues of trees is a perfect example of such a relationship.
Parasitism is similar to this but the other organism is harmed in the process.
Answer: No
Explanation: if a nucleic acid contains uracil then it is not DNA it's an RNA. Uracil is the basic nitrogenous base of RNA. DNA does not have Uracil in its structure. It contains thiamine instead of Uracil. So the answer is NO.
