Question

10 multiple choice 4 points until the late 1970s, there was no \domain\ as the broadest category in taxonomy. instead, there were five kingdoms: protista, plantae, fungi, animalia, and monera, which included all bacteria - like organisms. researchers proposed the domains to distinguish between the bacteria - like organisms. which information supported placing bacteria and archaea in separate domains? organisms in the bacteria and archaea domains have a nucleus, whereas eukaryotes do not. evolution led to new adaptations and diversity of organisms. cell shapes of bacteria and archaea were found to be more distinct, after microscope technology improved. more complex emergent properties developed after organisms were originally categorized into kingdoms. differences in dna among the existing kingdoms showed a need for a broader naming category. clear my selection 11 multiple choice 4 points which of these is not a required characteristic of life? homeostasis energy use

Explanation:

1. For question 10: Bacteria and archaea were placed in separate domains mainly due to differences in their DNA. This genetic - level distinction was a key factor in creating the domain classification. Bacteria and archaea are prokaryotes (lack a nucleus), so the first option is incorrect. Evolution leading to diversity is a general concept and not specific to the separation of bacteria and archaea into domains. Cell - shape differences are not the main reason for separating them into domains. Emergent properties are not the key factor for this domain separation.
2. For question 11: Homeostasis (maintaining a stable internal environment) and energy use are fundamental characteristics of life. Without homeostasis, an organism cannot function properly, and energy is required for all life - processes. The third option (not provided in full in the question but by elimination) is the answer as it is not a required characteristic of life.

Answer:

1. Differences in DNA among the existing kingdoms showed a need for a broader naming category.
2. (The third option not fully shown in the question)
