How does area usually affect biodiversity within an ecosystem? Responses
A. A larger area will usually contain about the same number of species as a smaller area.
B. A smaller area will usually contain more species than a larger area.
C. A larger area will usually contain more species than a smaller area.
D. Area has no effect on biodiversity.

C

Step-by-step explanation:

More area means more space for more species. a small area isn't likely to have bigger sized species

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
