100

A response to maintain balance in the body. (ex sweating when body temp. is high)

What is homeostasis?
100
The meaning of arrows in a food web.
What is energy?
100
Requires sunlight, water, and carbon dioxide to create sugar.

300

Shows the evolutionary relationship between species.

What is an evolutionary tree?

OR

What is a phylogenetic tree?


300

Found in the human body that help in biochemical reactions by breaking down molecules into smaller parts.

400

Structures that were useful in the past by ancestors but are no longer by the current species.

What is a vestigial structure?

400

A type of homeostasis that attempts to bring the body back to original state. (ex shivering to warm up)

What is negative feedback?
400
Biotic of abiotic conditions that prevent population growth to get too high.

400
The location where photosynthesis occurs.
What is a chloroplast?
500

What is variation?
500
A permeable bag of water is placed in a jar filled with water. In order for more water to enter the bag, this must be added to the jar.
