Species evolve at different rates. For example, bacteria are unlikely to become extinct because they adapt more quickly than mammals to environmental changes. Which of the following best explains this difference?

A.) Bacteria reproduce more rapidly, allowing the species to evolve more quickly.

B.) Bacterial populations are more isolated, permitting increases in genetic variability.

C.) Certain bacteria grow more steadily over time, giving an evolutionary advantage over mammals.

D.)Individual bacteria have the same genes, providing opportunities for increased biodiversity in one population.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.

Which best describes a benefit of using dna technology in medicine? a) medicine can be produced in mass quantities. b) medicine can be distributed at a reduced cost. c) medicines have fewer side effects. d) medicines are resistant to antibiotics.
