1. They are found in the cells of eukaryotic autotrophs and heterotrophs.
2. They include stacks of membranes that absorb light.
3. They include compartments where hydrogen ions are concentrated.
4. They produce sugars using energy harvested in the cytoplasm.
5. They break down sugar to produce ATP.

13)All of the following statements concerning the theory of evolution by natural selection are true EXCEPT:

1. Organisms produce far more offspring than are required for replacement.
2. The individuals in a population show variation in survivability and in their ability to cope with environmental stress.
3. The number of offspring that survive to reproduce varies among individuals.
4. The bodies of organisms in a population change by use and disuse, and the changes are inherited by the next generation.
5. Some of the variation in adaptation is the result of genetic differences that may be passed on to the next generation.

28)A scientist studying the oxygen concentration in sealed chambers containing cultured plant cells finds that when the chambers are illuminated, the concentration of oxygen increases. However, when the chambers are kept in the dark, the concentration of oxygen decreases. Why does the oxygen concentration decrease when the chamber is kept in the dark?

1. Plant cell mitochondria consume oxygen by aerobic respiration.
2. Plant cell chloroplasts run the photosynthetic pathways backward to consume oxygen.
3. Plant cell chloroplasts switch their structure and function and become mitochondria.
4. The chambers must not be properly sealed, so that oxygen is leaking out.
5. The cultures in the chambers must be contaminated with some animal cells, since only animal cells consume oxygen.
