Bio 100 Exam 1 SBCC Questions and Answers Already Passed

Bio 100 Exam 1 SBCC Questions and Answers Already Passed **Define Biology.** Biology is the scientific exploration of life. **What are the characteristics of Life?** Life is defined by traits such as (1) complex organization, (2) responsiveness to the environment, (3) reproduction, (4) evolution, (5) growth, (6) internal regulation, (7) homeostasis, and (8) energy processing. **Name the 5 Kingdoms.** The five kingdoms include Monera, Protoctista, Fungi, Plantae, and Animalia. **List the 3 Domains.** The three domains are Bacteria, Archaea, and Eukarya. **Describe the hierarchy of organization from smallest to largest.** This ranges from atom, molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem, to biosphere. **Define Science.** Science is the systematic study that seeks natural explanations for natural phenomena, focusing on observations that are observable, measurable, and variable. **Differentiate Discovery Science from Hypothesis-based Science.** Discovery Science involves describing natural phenomena, while Hypothesis-based Science applies the scientific method. **List the steps of the Scientific Method.** These steps are (1) Observation, (2) Formulation of a Question, (3) Hypothesis Development, (4) Prediction, and (5) Testing. **Define Matter.** Matter encompasses substances that possess mass and occupy space. **Define Element.** An element constitutes a substance that cannot be reduced to simpler substances. **Name the Essential Elements of Life.** These are carbon, hydrogen, oxygen, and nitrogen. **Define Atom.** An atom represents the fundamental unit of an element. **Explain Atomic Number.** The atomic number denotes the count of protons within an atom's nucleus, uniquely defining its element. **Define Atomic Mass.** Atomic mass signifies the combined total of protons and neutrons within an atom's nucleus. **Describe Electron Shells.** Electron shells are the designated regions surrounding the nucleus where electrons are located, capable of hosting either two or eight electrons. **Differentiate Inert and Reactive Atoms.** Inert atoms feature complete outer electron shells, while reactive atoms possess incomplete outer shells and are predisposed to bond formation. **Define Chemical Bond.** A chemical bond pertains to the interaction between atoms that results in the attainment of a complete outer electron shell, involving the transfer, reception, or sharing of electrons. **Define Ionic Bond.** An ionic bond is established through
