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)

no you cant do that

asma: toshiko wants to determine what type of freproduction a particualr single -celled organism undergroes .she conducts an experiment in which she anaylazes the chromosomes of the organism,she allows time for the the organisms to reproduce ,and then she anyalazes the chromoses of the duaghter cells.she discovers that all of the organisms offspring are gentically identical to the original orgaisinim asma: 1) identify the dependent (responding) varibale in toshikos experimnent.

number of organisms present

depends on time

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

is this biology or physics?
anonymous

idk

do you

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

looks like biology lol id say they reproduce asexually if its biology if math then the word that comes to mind is exponentially?

hello
anonymous
  • anonymous
So as I said the dependent variable should be the population
anonymous
  • anonymous
And id say it reproduces asexually meaning it splits apart (multiplies)
