Bacteria and Archaea a. b. Archaea and Eukarya Bacteria and Eukarya c. d. Can't decide Bacteria Archaea Eukaryotes Time Origin of LifeExplanation / Answer
1. e. It contains a nucleus
The presence or absence of a nucleus is not indicative of life, as one of the most major kingdoms of living organisms is comprised of bacteria, which lack a nucleus.
2. a. Population
In all other options, there is an interaction of multiple factors, biotic and abiotic. However, here, we are only considering a few isolated members of a single species, therefore population is the correct answer.
3. c. A protist
By definition, protists are eukaryotes which aren't animals, plants or fungi. They have organelles and a nucleus, unlike archae and bacteria.
4. c. A hypothesis
It is not an observation as it is not explicitly seen that pesticides are present in the water. A prediction is supposed to say what will change in the observation in the future, which is not the case here, as the presence of pesticides is said to be immediate. It isn't a theory as a theory is obtained after experimentation, and no experimentation is being carried out either, just a remark is derived out of an observation.
