If all the deer disappeared from this community, which change would be most likely to occur?
coyote-cougar
squirrel
mouse
deer
#
4
grass
acorns
mushrooms
A. The coyote population would decrease.
B. The squirrel population would decrease.
C. The grass population would decrease.
D. The grass population would stay the same.

I'm leaning towards A here.

Explanation:

Let's skip A for now. For B, it states that the squrrel...now think about it. Squirrels don't connect with deers so it probably isn't that. Next is C. It states that the grass population would decrease, however it may actually increase because then only the mouse is eating in (in this graph of course) and so D cannot be correct either. Now with A, it states that the coyote population would decrease. Now I don't know if this is very likely however it does make sense and so I think it's that.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
