Can you create me a practice test based on these quiz questions: The planet Mercury is closer to the sun than the planet Venus. However, temperatures on Venus are hotter than temperatures on Mercury. Why would this be the case? Mercury has a thicker atmosphere than Venus that blocks heat from the sun. Mercury spins more quickly than Venus, so its surface cannot heat up as quickly. Venus has a thicker atmosphere than Mercury that traps heat from the sun. Venus is cooled by high concentrations of water vapor in its atmosphere. **Question 2** **0.05 / 0.05 pts** Oxygen is produced during the light reactions when water is split to provide replacement electrons to chlorophyll. electrons reach the end of the electron transport chain. NADP+ is converted to NADPH. CO2 splits apart at the end of the light reactions. **Question 3** **0.05 / 0.05 pts** What happens when water is heated? It\'s broken into hydrogen and oxygen atoms. Hydrogen bonds between water molecules are broken. New hydrogen bonds are created between water molecules. Hydrogen atoms jump from one water molecule to another water molecule. **Question 4** **0.05 / 0.05 pts** Why is water so important in controlling Earth\'s climate? Water warms up quickly when very little energy is added to it. The evaporation of water from oceans and lakes cools the temperature of the continents. The water in oceans and lakes stores the energy radiated by the sun and releases it slowly. Water vapor is one of the greenhouse gases that allows the release of heat into space. **Question 5** **0.05 / 0.05 pts** Which of these human activities has directly contributed to global warming? development of solar energy planting of trees burning of coal building of greenhouses **Question 6** **0.05 / 0.05 pts** Which of these would be the most likely effect on precipitation from global warming? a decrease in the amount of snowfall on mountaintops an increase in the months of snowfall in higher latitudes a decrease in the amount of rainfall near oceans an increase in the amount of rainfall in every climate **Question 7** **0.05 / 0.05 pts** The full range of electromagnetic energy is called the \_\_\_\_\_\_\_\_ spectrum. ultraviolet electromagnetic visible energy **Question 8** **0.05 / 0.05 pts** What is the name given to organisms that can make their own food and thus sustain themselves without consuming organic molecules derived from other organisms? autotrophs heterotrophs chemotrophs **Question 9** **0.05 / 0.05 pts** What is the source of energy that provides the boost for electrons during photosynthesis? cellular respiration NADPH ATP light **Question 10** **0.05 / 0.05 pts** *After reading the paragraph below, answer the questions that follow.\ * *\ *The graph shows records of temperature (light gray line) and CO2 (dark gray line) over the past 1,000 years. CO2 is recorded in parts per million (ppm).\ \ \ If the trends shown in the graph continue, how might this affect photosynthesis? There would be no effect on photorespiration, since CO2 and temperature are stable. C4 and CAM plants would be unable to photosynthesize. Photorespiration may increase, leading to an increase in photosynthetic production of sugar. Photorespiration may increase, leading to a decrease in photosynthetic production of sugar. **Question 11** **0.05 / 0.05 pts** The ultimate source of all the food we eat and the oxygen we breathe is cellular respiration. glycolysis. photosynthesis. anaerobic metabolism. **Question 12** **0.05 / 0.05 pts** Glucose molecules are to starch as \_\_\_\_\_\_\_\_ are to proteins. amino acids fatty acids monosaccharides oils **Question 13** **0.05 / 0.05 pts** *After reading the paragraph below, answer the questions that follow.\ * ![](media/image2.png) *\ *The graph shows records of temperature (light gray line) and CO2 (dark gray line) over the past 1,000 years. CO2 is recorded in parts per million (ppm).\ \ \ If you focus on the data from the mid-1900s (indicated by the arrow) through today, the graph shows that there is a correlation between CO2 and temperature; when CO2 levels are high, temperature is low. there is no correlation between CO2 and temperature; CO2 fluctuates randomly and temperature is constant. there is a correlation between CO2 and temperature; when CO2 levels are high, so is temperature. there is no correlation between CO2 and temperature; CO2 is constant and temperature fluctuates randomly. **Question 14** **0.05 / 0.05 pts** Which of the following molecules is a reactant of photosynthesis? CO2 glucose chlorophyll O2 **Question 15** **0.05 / 0.05 pts** The energy that excites the photosystems is supplied by electrons passing down the electron transport chain. ATP. photons. NADPH. **Question 16** **0.05 / 0.05 pts** Why are most plants green? Chlorophyll *a* reflects green light. Green helps plants blend into their environment as a sort of camouflage. Chlorophyll *a* absorbs green light. Chlorophyll *b* primarily uses green light as the source of energy for photosynthesis. **Question 17** **0.05 / 0.05 pts** Which definition describes \"heat\"? the rate that molecules are moving within a substance the ability of a substance to transfer energy between its molecules the resistance to temperature change within a substance the total amount of energy associated with the movement of molecules in a substance **Question 18** **0.05 / 0.05 pts** The planet Mercury is closer to the sun than the planet Venus. However, temperatures on Venus are hotter than temperatures on Mercury. Why would this be the case? Mercury has a thicker atmosphere than Venus that blocks heat from the sun. Mercury spins more quickly than Venus, so its surface cannot heat up as quickly. Venus has a thicker atmosphere than Mercury that traps heat from the sun. Venus is cooled by high concentrations of water vapor in its atmosphere. **Question 19** **0.05 / 0.05 pts** Which of the following are produced during the Calvin cycle? ATP, NADPH, O2 ATP, NADPH, CO2 glucose, ADP, NADP+, CO2 glucose, ADP, NADP+ **Question 20** **0.05 / 0.05 pts** The conversion of CO2 and H2O into organic compounds using energy from light is called fermentation. cellular respiration. glycolysis. Photosynthesis. Which of the following is a true statement about chromosomes? The most complex organisms have the largest number of chromosomes. Genes are found on chromosomes. Only eukaryotic cells contain chromosomes. Chromosomes are made of carbohydrates. **Question 2** **0.05 / 0.05 pts** A heterozygous organism can\'t produce gametes. always shows a recessive trait. has two different alleles of a gene. has two identical alleles of a gene. **Question 3** **0.05 / 0.05 pts** Which of the following is a true statement about chromosome number? Among all known living creatures, humans have the most chromosomes. All organisms have pairs of chromosomes. Animals have more chromosomes than plants. Eukaryotes have more chromosomes than prokaryotes. **Question 4** **0.05 / 0.05 pts** Half of the gametes produced by an organism with the genotype *Aa* will receive the *A* allele, while half will receive the *a* allele. This is a demonstration of independent assortment. segregation. random fertilization. mutation. **Question 5** **0.05 / 0.05 pts** Homologous chromosomes are inherited together because they don\'t separate during meiosis. generally contain the same genes. almost always contain identical alleles. are fewer in body cells than in gametes. **Question 6** **0.05 / 0.05 pts** A scientist studying the heritability of IQ would expect to find the highest correlation between the IQ scores of a child and his mother. two unrelated children. monozygotic twins. dizygotic twins. **Question 7** **0.05 / 0.05 pts** If the estimated heritability of a trait is approximately 0.50, then the environment completely controls the variation in the trait in the population. genes exclusively control the expression of the trait in at least 50% of the population. at least 50% of the variation in the trait in the population is due to genetic differences. the environment must have little to no influence over the expression of the trait. **Incorrect** **Question 8** **0 / 0.05 pts** Which of the following was a conclusion based on experiments with \"maze-bright\" and \"maze-dull\" rats? A poor environment adversely affects maze-running ability in both bright and dull rats. Maze-running ability is highly heritable and unaffected by environment. An enriched environment increases maze-running ability only in dull rats. Maze-running ability is based entirely on environment and unaffected by genes. **Question 9** **0.05 / 0.05 pts** Typical quantitative traits are easy to follow using Punnett squares. show continuous variation. are usually influenced by only one gene. are not affected by the environment. **Question 10** **0.05 / 0.05 pts** In pea plants, the allele for purple flowers (*P*) is dominant to the allele for white flowers (*p*).
