A student sets up an experiment to determine whether temperature affects how many times a cricket chirps per minute. She sets up one tank with crickets at room temperature, one at a colder temperature, and one at a warmer temperature. All of the crickets are the same type and receive the same food and water. Each day at noon the student counts how many times the crickets at different temperatures chirp in one minute. What is the dependent variable?

yes!

explanation:

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

more words for this could be abiotic and biotic

abiotic: living organisms within an ecosystem

biotic: non-living organisms within an ecosystem

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
