ANSWER KEY FOR ALL QUESTIONS IN STUDY GUIDE
Basic Biological Principles
Multiple Choice Questions
B: The working cells release the needed materials C: The cells work to keep the organism alive D: The cells work to make a cycle C is correct because we know that cells are the functions of our bodies, the multicellular organisms are formed together into tissues, then they become organs, and then organ systems are created. They contribute to more than one cell to keep us alive. 2. What kind of cell is bacteria ? A: Eukaryotic B: Prokaryotic B is the correct choice because Eukaryotic cells are only living things like plants and animals, prokaryotic cells are non-living things as bacteria and all other cells that are non-living 3. There are certain structures in cells that have jobs to make certain things, what is the name ? A: organs B: systems C: organelles D: tissues C is the correct choice because organelles help make all the things that exist in the mitochandria, organelles are only in one type of cell, Eukaryotic. Open Ended Questions:
2.How come the nucleus is known as the “ the brain” of the cell ? The nucleus is known the “ the brain” because it collects and holds information that is needed to control the cell’s functions. Photosynthesis
Multiple Choice Questions:
B: Photosynthesis C:Aerobic respiration There are three stages in aerobic respiration, glycolsis which produces 2 ATP, the second stage does not produce any ATP only the materials, but the final stage Oxidative, produces the maximum amount of ATPWhat is the name of the pigment in the chloroplasts that is present in photosynthesis ? A: Chlor Synthesis B. Chlorophyll C. ADP D. Electron Transport Chlorophyll molecules are arranged in and around photosystems that are embedded in the thylakoid membranes of chloroplasts.3. Where is Photosynthesis produced ? A. Mitochondria B.Chloroplast Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.

Cellular respiration adds to photosynthesis by taking that the glucose that it produces and adding in the reactants of photosynthesis. |
The Chemical Basis of Life
Multiple Choice:
B: Magent C: Electrical molecule D: Polar molecule D is the correct answer because electric charges are positive, polar molecules have two opposite charges, positive and negative. 2. What two main elements make up the structure of water ? A: Oxygen and Carbon B: Helium and oxygen C: Hydrogen and Oxygen D: Helium, Carbon, and Hydrogen A water molecules has two hydrogen atoms that connects to one oxygen atom. 3. Which property of water is a versatile solvent but can also be called an “universal solvent” ? A: Polarity and Cohesion B: High heat and capacity C: Purity D: Expansion from being frozen Polarity has water molecules that stick to each other, cohesion gives the ability to stick to itself, and the hydrogen bonding makes them good solvents.

2. Give your own definition for temperature, concentration, and pH level. Temperature measures the warmth or coldness of a liquid, food, any substance or object. Concentration is to measure an amount of dissolved substances, and pH levels are what measures of hydrogen ion concentration in the body, it starts at 1 and goes up to 14, it stands for power of hydrogen. Homeostasis
Multiple Choice Questions:
B: Active Transport C: Facilitated Transport D: Simple Diffusion https://biologydictionary.net/osmosis/
B: Fever C:Blood Clotting D: Sweating Sweating is the correct answer because it cools down the body until it gets back to its normal state.
B: A regulation of organisms that have internal conditions that maintain conditions equally. C: Chemical reactions that organs D: A type of name for all cells https://biologydictionary.net/homeostasis/ Open Ended Questions:
2. If you are somewhere, where it is cold, your body will start to shiver because… Shivering produces heat. |
