Answer:
The correct option is <em><u>B. Eukarya only</u></em>
Explanation:
Bacteria can be described as prokaryotic organisms that do not possess a nucleus. Their genetic material is generally present in the cytoplasm of the cell in a region called nucleoid. Some extra genetic material is found in them in the form of plasmids. Hence, option D is not correct.
The domain, Archae, contains prokaryotes and they lack a nucleus. Hence, option A and C are not correct.
Eukaryotes are multicellular organisms which contain a nucleus and other membrane-bound organelles. Hence, option B is correct.
The
correct answer is they filter urea from blood and produce urine.
<span>
Nitrogenous
wastes tend to form toxic ammonia which needs to be removed. Terrestrial
animals must detoxify ammonia by converting it into a relatively nontoxic molecule-urea
(it occurs in the urea cycle). The urea cycle mainly occurs in the liver and the
produced urea is then released into the blood. It travels to the kidneys where
is filtrated and excreted in urine.</span>
Answer: Yes
Explanation:
I’m not sure why it seems right tho
Answer:
Antibiotics disrupt essential processes or structures in the bacterial cell. This either kills the bacterium or slows down bacterial growth. Depending on these effects an antibiotic is said to be bactericidal or bacteriostatic.
