Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes.
So..the answer should be D. Eukaryotic cells have a true membrane-bound nucleus and prokaryotes do not
All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.
So..it can't be C. or A. or even B.
Correct me if I'm wrong.
Answer:
Involve changes in one or few nucleotides/ bases

Point mutations most commonly involve the substitution of one base for another (which changes the complementary base as well in DNA). The term point mutationt also includes insertions or deletions of a single base pair.
Answer:
Whether or not it affects the composition of rocks.
Explanation:

For example, mechanical weathering breaks rocks into smaller pieces without changing their composition, whereas chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
i do hope that this helps!
