Question

Which of the following does NOT describe the macronucleus of a paramecium?

A. The macronucleus forms from the fusion of micronuclei.

B. The macronucleus has multiple copies of the genes that are used in day-to-day activities.

C. The macronucleus does not disintegrate during conjugation.

D. The macronucleus is not exchanged during conjugation.

Answer 1

1. what are protists

eukaryotes that are not other kingdoms

2. how protists= eukaryotes

common ancestor.

3. nonmotile protist

moved by current

4.Scientists once classified protists

many protists don't have any characteristics similar

5. macronucleus of paramecium

does not disintegrate

Step-by-step explanation:

Answer 2

The answer is letter D. The macronucleus is not exchanged during conjugation. It normally contains the working duplicates/copies of genes necessary to support an enormous cell. Macronucleus is formed by a direct division of the polyploid nucleus right after conjugation then followed by series of internal gene replication that is not oftenly occurring in micronucleuse.
