Nucleic acids are important information storage molecules present in virtually every cell. Which of the processes is carried out by a cell when it accesses that information in the DNA of the genes? a. transcription and translation b. DNA replication and transcription c. DNA replication and translation ANSWER: a 2. Observations are used by scientists to draw tentative explanations called hypotheses. a. true b. false ANSWER: a 3. When small molecules are linked together to form larger molecules, the increase in entropy typically comes from: a. gas produced. b. light captured (for example, in photosynthesis). c. work done (for example, creation of new bonds in larger molecules). d. heat loss. e. enzymes utilized. ANSWER: d 4. Which process is an example of the first law of thermodynamics in action? a. As monomers combine into polymers, the disorder inside the cell decreases. b. Light energy is transformed into chemical energy during photosynthesis. c. Energy is created by cells during ATP synthesis. d. Some energy is released as heat during metabolic processes. ANSWER: b 5. Consider the image. If the ostrich egg shown in the photo is not fertilized, it is composed of approximately how many cells? b. 100 c. 10,000 d. 1,000,000 e. 100,000,000 ANSWER: a 6. Imagine that you are standing in a field and you see a group of butterflies. You notice an individual butterfly that looks significantly different from the others in the population. Its difference allows the butterfly to escape predation more efficiently than the other butterflies. How might this trait have arisen in the individual? a. There were more predators in the surrounding area, so the butterfly needed the trait in order to escape predation. b. There was a mutation in a gene that led to differences in the ability to attract mates. c. There was a random mutation in a gene that led to differences in the ability to escape predation. d. There were more predators in the surrounding area, so the butterflies allowed themselves to be caught to save the faster butterflies in the population. ANSWER: c 7. All of the classifications are considered domains of life except: a. Bacteria. b. Eukarya. c. Archaea. d. Protists. e. Protists, Eukarya, Archaea, and Bacteria are all domains of life. ANSWER: d 8. Consider the phylogenetic tree. According to this phylogenetic tree, the primate most closely related to humans is the: a. lemur. b. chimpanzee. c. gorilla. d. orangutan e. gibbon. ANSWER: b 9. Trees in the desert and trees in the rainforest experience vast differences in the amount of water available for uptake. Water can be lost from the leaf surface very easily in dry and hot regions. What types of differences might you expect between tree species in a rainforest compared with those in a desert? Copyright Macmillan Learning. Powered by Cognero.
