D. Dizziness
E. Bowels obstructions

Answer:
animal is the correct answer.
Explanation:
The fungus is more closely related to animals than to plants because of the following reasons:
- fungus are heterotrophs that mean they are not able to make their food like animals.
- The fungus is closely related to animals that have signified defined by molecular phylogenetic analyses.
- Fungi have chitin in their cell wall like animals.
Answer:
This experiment proved that DNA replicated semiconservatively; half the original polynucleotide is conserved in each of the two copies
Explanation:
Semi-conservative mode of replication means that the two strands of DNA unwind from each other, and each of themacts as a template for synthesis of a new, complementary strand. As a result, two formed DNA moleculesc ontain one original strand and one new strand.
Meselson and Stahl experiment showed this model by labeling the DNA of bacteria across generations using isotopes of nitrogen ( patterns of DNA labeling showed the mode of replication).
