Q: Q: Comparisons of amino acid sequences can shed light on the evolutionary divergence of what? Read this paragraph and choose the correct option from the provided answers: Choices: - mammals - dinosaurs - birds - related species A:
A: related species

Q: Q: What are subatomic particles of the nucleus called? Read this paragraph and choose the correct option from the provided answers: Summary Subatomic particles of the nucleus (protons and neutrons) are called nucleons. Anuclide is an atom with a particular number of protons and neutrons. An unstable nucleus that decays spontaneously is radioactive, and its emissions are collectively called radioactivity. Isotopes that emit radiation are calledradioisotopes. Each nucleon is attracted to other nucleons by the strong nuclear force. Stable nuclei generally have even numbers of both protons and neutrons and a neutron-to-proton ratio of at least 1. Nuclei that contain magic numbers of protons and neutrons are often especially stable. Superheavy elements, with atomic numbers near 126, may even be stable enough to exist in nature. Choices: - baryons - cores - isotopes - nucleons A:
A: nucleons

Q: Q: What kind of energy is released when the thermochemical reaction of a campfire converts wood to carbon dioxide and water? Read this paragraph and choose the correct option from the provided answers: A camp fire is an example of basic thermochemistry. The reaction is initiated by the application of heat from a match. The reaction converting wood to carbon dioxide and water (among other things) continues, releasing heat energy in the process. This heat energy can then be used to cook food, roast marshmallows, or just keep warm when it's cold outside. Choices: - ultraviolet - light - smoke - heat A:
A: heat

Q: Q: In what type of climate might one find deciduous trees? Read this paragraph and choose the correct option from the provided answers: Deciduous trees are common in humid continental climates. Conifer forests grow in the subarctic. Choices: - thick continental - Dry Continental - moist continental - humid continental A:
A: humid continental
