They reproduce. They respond to stimuli. They are complex and organized. They acquire energy. all of the above The three natural processes that form the basis for evolution are adaptation, natural selection, and inheritance predation, genetic variation, and natural selection mutation, genetic variation, and adaptation fossils, natural selection, and adaptation genetic variation, inheritance, and natural selection Which cell listed is considered to be most primitive in its evolution? protistan prokaryotic autotrophic yeast eukaryotic Which of the following is not a kingdom? Animalia Fungi Monera Insecta Protista Living organisms are characterized by which of the following? organic structure responsiveness to stimuli maintenance of homeostasis b and c are correct. a, b, and c are correct. The organization of life is defined as follows: Organisms are neat and tidy compared to non-living matter. Organisms are simple in structure, containing a few compounds repeated over and over. An organism's DNA is arranged in strands. Organisms contain thousands of different compounds arranged in specific ways to form cells. Actually, only some living things are organized; many are not. In reproduction, which of the following must occur? passing DNA from parent to offspring two parents copulation sperm and egg all of these In an organism, evolution is defined as a change from pre-existing life forms to modern-day forms. What actually changed? rate of reproduction ability of organisms to cope with external stimulus energy and nutrition demands of the organisms genetic makeup of the species the species' physical appearance Mutations are crucial to the survival of a species because mutations increase newborn survival are the source of genetic variation reduce the need for sexual selection support stable population growth rates eliminate the weak from the population A scientist collects pond water from a local fishing hole. She filters out the different organisms into separate jars. She adds no food to the water, but one kind of organism is still alive long after all others have died. That species is probably homeostatic heterotrophic microtrophic hydrophilic autotrophic Which of the following is a scientific explanation that is tentative and requires more investigation? theory fact control hypothesis observation Designed in cooperation with Andrew Stull and Steven Brunasso.
