Question: Which of the following options does NOT represent how osmoregulation occurs within humans?
Answer Options:
waste materials not reabsorbed are excreted as urine
a lot of energy is utilized in the reabsorption process
blood pressure forces water and other solutes out of blood capillaries in the filtration process
only a limited amount of water is reabsorbed in the process
Answer: only a limited amount of water is reabsorbed in the process
Question: Which of the following is NOT a form of kinetic energy?
Answer Options:
a covalent bond that links the carbon atoms in a molecule of glucose
a pitcher throwing a baseball
a ball rolling down a hill
water moving down a water wheel that causes the wheel to turn
Answer: a covalent bond that links the carbon atoms in a molecule of glucose
Question: Which of the following scenarios describes the conversion of kinetic energy into potential energy?
Answer Options:
Water stored by a reservoir is released over a dam to turn a turbine and produce electricity
Glucose in the body used to produce motion of muscles for running
Light from the sun is stored in the form of glucose by a tree
Wood is placed in a fireplace and burned to heat the room
Answer: Light from the sun is stored in the form of glucose by a tree
Question: Which statement best describes the first law of thermodynamics?
Answer Options:
energy can be created or destroyed
when energy is converted from one form to another, some of it is lost as useless energy
the amount of energy in the universe changes and fluctuates
energy cannot be destroyed or created, but it can change forms
Answer: energy cannot be destroyed or created, but it can change forms
Question: Each ATP molecule is composed of three separate subunits. Which of the following is NOT one of these subunits?
Answer Options:
an amino acid
a 5 carbon sugar
three phosphate groups
an adenine nucleotide
Answer: an amino acid
Question: Energy needs to be added or is required for which of the following situations to occur?
Answer Options:
ATP releasing one of its phosphate groups to become ADP
ADP gaining a phosphate group to become ATP
Answer: ADP gaining a phosphate group to become ATP
Question: Which one of the following statements BEST represents the relationship between respiration and photosynthesis?
Answer Options:
Photosynthesis is just a complete reverse of the biochemical pathway of respiration
Photosynthesis stores energy in complex organic molecules, while respiration releases it
Respiration occurs only in animals and photosynthesis occurs only in plants
Photosynthesis occurs only in the day and respiration occurs only at night
Answer: Photosynthesis stores energy in complex organic molecules, while respiration releases it
