Your friend is really irritable while sitting in class. He feels lightheaded and dizzy. He is also feeling a bit of confusion and brain fog.
What inferences are most realistic to make about the biomolecules in your friend's body?
He is running low on fast sources of energy
Proteins are being broken down or reshaped
The coding information in the cell is incorrect or incomplete
There is not enough insulation or energy storage

Dystrophin is a molecule that holds muscle fibers together. In people with muscular dystrophy, a genetic disease that causes people to lose the ability to walk at a young age, dystrophin molecules never develop.
What can you infer about the biomolecules of affected individuals? (select all correct answers)
There is a lack of sources of fast energy
A biomolecule is missing
The coding information in the cell is incomplete or incorrect
If removes insulation and long term energy storage

Bowhead whales can have a specialized layer of blubber up to 30 cm’s thick. This acts as a special insulation that traps the heat their muscles create from movement.
What biomolecule is the blubber primarily made of?
Carbohydrates
Lipids
Proteins
Nucleic Acids
Helicase is an example of a biomolecule that can destroy bonds between DNA strands during DNA replication.
What biomolecule is helicase?
Carbohydrate
Lipid
Protein
Nucleic Acid
A scientist discovers new life on a distant planet. While watching the alien species live on the planet, scientists begin to notice that in order to hunt this species will attack another smaller species and inject them with some sort of liquid. After a short time, the smaller organism develops a sort of necrosis which is when a small portion of the organism's flesh begins to break down. Soon after necrosis begins the smaller organism dies.
What can you infer about the function of the poison?
It decreases fast sources of energy
Proteins are being broken down or reshaped
The coding information in the cell is altered
If removes insulation and long term energy storage

There is a person with Albinism. This individual does not produce melanin. Melanin allows for people to be protected from the sun. Since Albinos do not produce this protein they are prone to getting sunburns.
What inferences are most realistic to make about the biomolecules in this individual's body?
He is running low on fast sources of energy
Proteins are being broken down or reshaped
The coding information in the cell is incorrect or incomplete
There is not enough insulation or energy storage

What biomolecule results in the individual having albinism?
Carbohydrates
Lipids
Proteins
Nucleic Acids
