behavior
____ is the study of interactions of organisms with each other and the environment.

Cutting open many leaves from trees and examining them under a microscope you find the tissues for photosynthesis are always in the middle layer with a
protective layer of cells surrounding the leaf.
Which characteristic of life is this?

B. insight learning.
C. extinction.

Jeff wants to know what concentration of bleach would be most effective at killing bacteria without overdoing it and using too much bleach. Jeff makes 3 solutions of bleach in water, 1, 5, and 10% solutions. He then adds a specific number of bacteria to a test tube of each solution and waits 3 minutes. He puts these bacterial on a petri plate and later counts colonies to see how many bacteria survived. In this experiment, the
number of bacteria that were killed would be:
response/dependent variable
Is a high-energy molecule, undergoes hydrolysis and energy is released, is the energy "currency" of the cell.
What nucleic acid is this?
ATP (adenosine triphosphate)
What is a form of communication that would be the most effective in a dense forest?
Auditory communication
A population of 100 butterflies living on an acre of land loses three-quarters of its members when a sudden freeze in the spring occurs just after they emerge as
caterpillars. This population has undergone a reduction in population size due to
a density-independent factor
The conversion of nitrate back to nitrogen gas is called
denitrification (nitrogen cycle)
