An engineer is designing a new synthetic product that requires a waterproof coating. What biomolecule has the characteristics that he should try to replicate?
What relationship exists between amino acids and proteins?
A scientist discovered a new organism in a rainforest. She is studying the DNA of the organism to find its similarity to other organisms.
What nucleotides will be present in the DNA sequence of the newly discovered organism?
When athletes run long distances, their muscles become fatigued due to a lack of oxygen. Which process helps athletes generate more energy to continue running?
How are the reactions of photosynthesis and cellular respiration interconnected?
The reactions are opposites of one another, each using the products of the other as reactants.
Both reactions require ATP as the energy source, but photosynthesis only happens in plants.
Every organism carries out both processes at the same time but in different parts of the organism.
Animals rely on photosynthesis in plants, and plants rely on respiration as the source for their ATP.

proteins that act as hormones
carbohydrates that are important fibers
carbohydrates that store energy
Why are many plants green?
plant cells are green
plants absorb green light
chlorophyll reflects green light
rigid cell walls are green
Why are carbohydrates important for organisms?
Which statement best explains why animals are considered heterotrophic?

They are able to produce food through the process of respiration.
They are able to obtain nutrients by decomposing plant and animal tissue.
They are able to obtain nutrients by consuming other organisms or their products.
