Which 4 of these 25 make of 96% of living matter? - carbon, hydrogen, nitrogen, oxygen Knowing just the whole number of an element allows inferences about which of the following? - the number of protons plus neutrons in the element When two atoms have the same level of attraction for electrons, the type of interaction between these two atoms can be described as - nonpolar covalent bond What is the difference between cov...

Biophilia - The instinctive bond between humans and other living systems Science - a body of knowledge about the natural world and an evidence-based system for obtaining such knowledge Scientific Method - The core logic of how science works. Commonly visualized as a series of logical steps through which scientific inquiry is conducted, scientific phenomena are demonstrated, and scientific knowledge come to be established Scientific Hypothesis - Informed, logical and plausible explanation ...

Biology - You Is the study of the science of life. It's not just facts and theories. It is also a process. Modem science, including biology, is primarily dependent on inductive logic reasoning, which has given rise to the Scientific Method General methods of critical thinking: Deductive Reasoning - Reasoning from a general premise to a specific conclusion. General methods of critical thinking: Inductive Reasoning - Reasoning from a series of specific facts or observations to a general pri...
