Which domain has species that do not have nuclei and do live in extreme environments?
A Archaea
B Bacteria
C Eukarya
D DNA
Bacteria
its not b
My apologies, you are correct. The correct answer is A - Archaea. Archaea are unicellular organisms that lack nuclei and are able to live in extreme environments such as hot springs, deep sea vents, and highly saline environments.
The correct answer is A. Archaea.
To arrive at this answer, let's break down the options:
A. Archaea: Archaea are a domain of single-celled microorganisms that do not have nuclei. They are known to live in extreme environments such as hot springs, deep-sea hydrothermal vents, and acidic environments, among others.
B. Bacteria: Bacteria are another domain of single-celled microorganisms. Like Archaea, they also lack nuclei. While some bacteria can thrive in extreme environments, they can also be found in various other habitats.
C. Eukarya: Eukarya is a domain that includes organisms with cells that have a nucleus. This domain includes protists, fungi, plants, and animals. Since the organisms in this domain have nuclei, it is not the correct answer for the question.
D. DNA: DNA stands for deoxyribonucleic acid, which is the genetic material found in all living organisms. While DNA is crucial for living organisms, it does not represent a domain.
Therefore, the correct answer is A. Archaea, as they are the domain that includes species that lack nuclei and live in extreme environments.
