D) The shark pup inherited its copies of the gene for fin shape from its mother and not from its father. Just like its mother’s genes, those genes instruct for proteins that connect in ways that make its fin pointed.
A) The shark pup inherited one copy of the gene for fin shape from its mother and one copy from its father. That gene combination instructs for proteins that connect in ways that make its fin pointed.
- A father pig has a curly tail while the mother pig has a straight tail. Which of these statements explains why one of their piglets could have a curly tail?
A) The piglet inherited its copies of the gene for tail shape from its father and not from its mother. Just like its father’s genes, those genes instruct for proteins that connect in ways that make its tail curly.
B) The piglet inherited its copies of the gene for tail shape from its father and not from its mother. Those genes connect together to make its tail curly.
C) The piglet inherited one copy of the gene for tail shape from its father and one copy from its mother. Those genes connect together to make its tail curly.
D) The piglet inherited one copy of the gene for tail shape from its father and one copy from its mother. That gene combination instructs for proteins that connect in ways that make its tail curly.
D) The piglet inherited one copy of the gene for tail shape from its father and one copy from its mother. That gene combination instructs for proteins that connect in ways that make its tail curly.
- A patient has been eating healthy foods, but her respiratory system is not working as well as it usually does. Can this patient still exercise normally?
A) Yes, her body can get everything it needs for energy from molecules in food.
B) No, her respiratory system does not have enough oxygen to combine together to release energy.
C) No, her cells do not have enough oxygen to react with glucose and release energy.
D) No, her cells do not have enough oxygen to react with proteins to release energy.
C) No, her cells do not have enough oxygen to react with glucose and release energy.
- Asthma is a condition in which it can be very hard for a person to breathe in enough air. Would it also be difficult for someone with asthma to exercise?
A) No, as long as the person is getting enough sleep, he will make enough energy to exercise.
B) No, as long as the person’s cells are getting different types of molecules from food, he can still exercise.
C) No, the person’s cells may not have everything they need, but his body can still exercise normally.
D) Yes, it will be difficult for a person with asthma to exercise because his cells need molecules from air.
D) Yes, it will be difficult for a person with asthma to exercise because his cells need molecules from air.
- A student thinks that the human body only works properly when cells are getting molecules from food and molecules from air. Is the student correct?
A) Yes, the body only works when cells get molecules from food and molecules from air.
B) No, the body only works when cells are getting molecules from different types of food.
C) No, the body only works when the lungs get molecules from air, and the stomach gets molecules from food.
D) No, the body works as long as cells are making all the molecules they need.
A) Yes, the body only works when cells get molecules from food and molecules from air.
- Some problems with the digestive system make it very difficult for the body to digest enough food. Why would it be harder to exercise when you have a digestion problem like this?
A) You would not be able to sleep, which would make you too tired to exercise.
B) Your cells would have molecules from air, but would not get enough molecules from food.
C) You would need to breathe in a lot more air because your body would have fewer molecules from food.
D) You would not get any of the molecules your cells need to exercise.
B) Your cells would have molecules from air, but would not get enough molecules from food.
- Doctors tested a patient and found that his cells contained normal levels of oxygen and glucose molecules, and no starch molecules. Will this patient be able to exercise normally?
A) Yes, the glucose and oxygen molecules can react together to release energy for the body to function.
B) No, his digestive system is not breaking down food molecules; his cells need starch molecules to react with glucose, which releases energy.
C) No, his body systems are working, but he needs to eat different food; in cells, only amino acids can react with oxygen to release energy.
D) Yes, as long as his cells have glucose, they don’t need anything else to release energy for the body to function.
A) Yes, the glucose and oxygen molecules can react together to release energy for the body to function.
