If a single-celled organism is found to have a nucleus which contains its dna and a phospholipid membrane, what else can safely be assumed about it? a. it is a member of the domain eukaryota even though it cannot reproduce on its own. b. it has mitochondria and is a member of the domain eukaryota. c. it has a cell wall and can photosynthesize and could belong to the domain bacteria. d. it has no other organelles besides the nucleus and is a member of the domain bacteria.

B. It has mitochondria and is a member of the domain Eukaryota.

Explanation:

Eukaryota cells can form snglie celled or multicelled organisms, but what makes them Eukaryota is the fact that they have a nucleus where they store all of the DNA of that cell, it also means that if it  is a Eukaryota cell it has to have a mitochondria to carry out the functions of energy conversion in the cell, so the best option would be B. It has mitochondria and is a member of the domain Eukaryota.

b is the best answer for this question.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
