A. They had different types of food. This resulted in many different breeds of finches.
Answer:
They can change over time because when you combine two different species together they can turn into a new and different specie. This shows that artificial selection can provide evidence that species can change over time.
The experimental design that the scientists used was read the genome sequence to determine the quantity and organization of operons
Observations are recording something that is already there
(qualitative and qauntitative)
an inference is an assumption or conclusion that is logically made
You have to find the acceleration first. so you would use the equation a=Vf-V0/t.
This would be 0-20/0.5 which equals to be a=-40. then you plug this in to the force equation wich is F=ma. F=55 x -40. F= -2200
Hope this helps!
