passage 809
question 17.
question 18.
do these organisms share the same domain?
a. no, only the orange and snake are in the same domain because mushrooms cannot photosynthesize.
b. yes, they are all in the same domain because they are prokaryotic.
c. yes, they are all in the same domain because their cells possess nuclei.
d. no, only the mushroom and orange are in the same domain because their cells have cell walls.

Explanation:

• Mushroom is a fungus, orange is a plant, and snake is an animal.
• All fungi, plants, and animals are eukaryotes (cells have nuclei) and belong to the domain Eukarya.
• Option A: Mushroom (fungus) and snake (animal) cannot photosynthesize. Orange (plant) can. So this option is wrong.
• Option B: Mushroom (fungus), orange (plant), and snake (animal) are all eukaryotic (not prokaryotic). Prokaryotic organisms are in domains Bacteria or Archaea. So this option is wrong.
• Option C: Since they are all eukaryotic (cells have nuclei), they are in the same domain (Eukarya). This option is correct.
• Option D: Only plant cells (orange) have cell walls. Fungal (mushroom) cells have cell walls made of chitin, and animal (snake) cells do not have cell walls. So this option is wrong.

Answer:

C. Yes, they are all in the same domain because their cells possess nuclei.
