Biology Semester 1 Final

Why do lions hunt in groups?

• they do not hunt in groups.

• they behave this way to get enough energy to survive.

• They are forced to.

• because it is fun to hunt in groups.

Why would lions live in groups in regards to genetics (what you inherit from mother and father)?

• Lions only take care of those they don't share genes with.

• Genetics has nothing to do with living in groups.

• They take care of cubs only because cubs can't take care of themselves.

• They live in groups to pass on their own genetics through their cubs.

A new species is found frozen in a glacier it has very flat teeth and its digestive system has an enlarged caecum. What would you classify this animal as and what type of food does it likely eat?

• Carnivore; Proteins

• Carnivore; Cellulose

• Herbivore; Proteins

• Herbivore; Cellulose

What are the four macromolecules?

• Proteins, Lipids, Carbohydrates, and Nucleic Acids

• Lipids, Sucrose, DNA, and Fats

• Proteins, Fats, Water, and Earth

• Proteins, Lipids, Sucrose and Nucleic Acids

The light independent reaction in photosynthesis does what?

• Only takes in sunlight.

• Uses H2O to make O2

• Uses CO2 and ATP in order to make Glucose

• Animals use the process to get direct energy from the sun

Plants have one organelle for performing photosynthesis and one in common with animals. What are they?

• They only have chloroplasts

• They only have mitochondria

• They have only mitochondria

• Chloroplasts and mitochondria

Why is nitrogen fixation important?

• it isn't we can get nitrogen from the air.

• Bacteria make it a usable form for plants to use

• Bacteria eat the nitrogen so it doesn't poison the food web

• It is the process of nitrogen being turned into O2

What is an example of a reservoir in the carbon cycle?

• carbon has no reservoirs

• Outer space

• Plants

The Law of Conservation of Energy states...

• matter can be created or destroyed

• matter is only transferred through heat

• matter can not be created nor destroyed only transferred from one form to another

• matter does not matter

Cell membranes are made with...

• DNA

• Proteins

• Lipids

• Sucrose
