What is the relationship between Photosynthesis and Cellular Respiration?

• Photosynthesis uses C6H12O6  as a reactant.
• Cellular Respiration and Photosynthesis both use water in the forward reaction.
• Photosynthesis is the reverse reaction to the Cellular Respiration reaction.
• Cellular Respiration has the same forward reaction as Photosynthesis.

Which of the following explains why elements, such as carbon and oxygen, that are used in organic molecules are not permanently removed from the environment?

• They are replenished by sunlight.
• They are cycled through ecosystems.
• They are replaced by volcanic eruptions.
• They are produced constantly from nutrients.

Which statement best explains why a food web is a more realistic representation of nutritional patterns than a food chain?

• Which statement best explains why a food web is a more realistic representation of nutritional patterns than a food chain?
• Decomposers return materials from the top-order predators to inorganic form.
• Energy always flows through the consumers to the producers.
• Practically all species are consumed by or feed on more than one species.

Genes contain the instructions that code for

• The shape of a protein
• How to wash your clothes
• How you look
• How you talk

Which conditions cause the body to work to maintain homeostasis?

• tissue and cell formation
• production of key vitamins
• cell differentiation and determination  
• internal and external changes

What happens if the codons in the DNA sequence were changed as follows:
_{ACU GGU CCA -> GGU ACU CCA}

• The protein that is made would not be the right one. It might be misshapen. (mutated)
• Nothing, the protein would be fine
• Nothing, DNA codons and proteins are not related
• The protein that is made would be typical of the gene

Place the five levels of human organization in the proper order (smallest to largest)

• Organism, organ system, organ, tissue, cells
• Cells, tissue, organ, organism, organ system
• Organ, cells, tissue, organism, organ system
• Cells, tissue, organ, organ system, organism

If there are more births than deaths in a population, what is happening to the population?

• It is stagnating (not growing or shrinking)
• It is growing
• It is shrinking
• Nothing, it is staying the same
