Answer 9

I'm trying to say when you have a a number raised to a negative exponent its 1 divided by the number to the positive exponent.
So like the first one
3^-2 is the same as 1/(3^2)

asma: 1) identify the dependent (responding) varibale in toshikos experimnent.

Answer 22

number of organisms present

Answer 23

depends on time

Answer 24

from toshikos results ,draw a conclusion about how this organism reprodues.

Answer 25

is this biology or physics?

Answer 26

idk

Answer 27

do you

Answer 28

for the fisrst qestion it doesnt tell you the number of organisms
