Let's check our knowledgeVocabulary Concepts Applications and Practice Crosscutting 1. The structure, properties, and transformations of matter can best be explained by which of the following? A. The way in which electromagnetic radiation interacts with different substances B. Gravitational forces from the environment on subatomic particles C. The number of atoms of an element in one mole of that substance D. Attraction and repulsion between electric charges at the atomic level 2. Polymers are substances that are often flexible and durable. These properties are best explained by the fact that polymers are– A. large molecules synthesized through complex laboratory procedures. B. made, predominantly, of carbon, hydrogen, and oxygen. C. molecules consisting of long chains of repeating units of atoms. D. substances produced by plants that have these properties. 3. Which of the following statements regarding the energy produced during cellular respiration is most accurate? A. The majority of the energy produced is lost to the environment as heat. B. The energy must be transferred across the cell membrane to be used. C. The energy produced must be stored in specialized organelles within the cell. D. The amount of energy produced is greater than the amount of energy required. 4. Shown here is an incomplete chemical equation for the reaction known as photosynthesis. 6CO2 + 6H2O + light energy → 6O2 + ____ Which of the following substances correctly completes the equation? A. Water B. Carbon dioxide C. Glucose D. Oxygen 5. Which of the following summarizes the flow of matter and energy in cellular respiration? A. Energy is consumed to rearrange carbon dioxide molecules into glucose and oxygen. B. Carbon and energy are required to transform sugar molecules into water molecules. C. Energy is released when sugar and oxygen are recombined to form carbon dioxide and water. D. As oxygen and carbon dioxide are used, energy and glucose are consumed. 6. Albumin is a protein produced in the liver of both pigs and humans. Based on this information, what other similarity can we predict between these two organisms? Both organisms– A. have more complex DNA than organisms that do not produce albumin. B. have DNA that codes for globulin, another protein found in the liver. C. produce new sequences of DNA in the same region of their livers. D. share a similar sequence in one section of their DNA that codes for albumin. 7. Which of the following observations would support the claim that DNA determines the structure of proteins produced by cells? A. Organisms that produce proteins have different lengths of DNA. B. Similar DNA sequences are found in organisms that produce the same protein. C. Both DNA and the production of proteins was observed in early life forms. D. DNA is found in the nucleus of all cells that produce proteins. 8. Huntington’s disease (HD) is a condition which results from the inability to produce a certain protein. Which of the following is most likely the cause of Huntington’s disease? A. A structural problem within the nucleus B. An increase in glucose in the blood C. A decrease in the fat intake of their diet D. A miscoding in the DNA sequence 9. Which of the following processes is directly responsible for growth in living organisms? A. The division of cells into two identical cells B. The movement of water across a cell membrane C. The production of reproductive cells called gametes D. The exchange of the gases oxygen and carbon dioxide 10. DNA replication is an important part of cellular division because correct replication– A. ensures that identical and complete genetic information is passed to both daughter cells. B. produces mutations that usually are advantageous for the survival of the organism. C. combines sperm and egg to form a zygote that will develop into a new organism. D. communicates information about the cellular environment to adjacent cells. Main PointsPhotosynthesis takes energy from the sun and carbon dioxide to make sugar and oxygen
Energy moves because of attraction and repulsion of charges DNA code makes proteins Monomer: One, Polymer: chain of monomers DNA replication leads to 2 daughter cells with identical DNA
