Question

4 a scientist had identified a multicellular organism. she studies some of the cells and observes that they have nuclei and cell walls. based on this information, the scientist can conclude which of the following statements about the classification of the species? (1pt)
a the species could be classified in domain archaea if it lives in extreme environments.
b the species could be classified in kingdom animalia if its cells have cell membranes.
c the species is classified in domain eukarya.
d the species could be classified in domain bacteria if it has circular dna.

Explanation:

1. Analyze Option A: Archaea are unicellular prokaryotes (no nuclei), so this is invalid.
2. Analyze Option B: Animal cells lack cell walls, so this is invalid.
3. Analyze Option C: All eukaryotic cells have a nucleus, and eukaryotes include multicellular organisms with cell walls (e.g., plants, fungi). This matches the observations.
4. Analyze Option D: Bacteria are unicellular prokaryotes (no nuclei), so this is invalid.

Answer:

C. The species is classified in domain Eukarya.
