Answer:
Mass = 40 kg Weight = 64 N
Explanation:
Mass does not change. 40 kg on Earth = 40 kg on the moon = 40 kg on Saturn, etc.
Weight = Force = Mass*Acceleration
So, Weight = 40 kg * 1.6 M/s^2 = 64 newtons
The answer is 300nm x 18nm
Answer:
backcrossing
Explanation:
when you cross the offspring (inttermediate size) to one of the parental strains, (the small strain for example) you should get 1/2 intermediate size and 1/2 parental size (small) if body size is due to single gene. On the other hand if the trait "size" is polygenic you should get mice around half way between small and intermediate sizes.
