Let's make the alleles Tt, where T is dominant (tongue rolling) and t is recessive (inability to tongue roll).
The heterozygous tongue roller would be Tt and the non tongue roller would be tt. Putting them in a punnet square (refer to attachment), the chances that their child will be a non tongue roller would be a 50% chance.
Tt: 2/4 = 50%
tt: 2/4 = 50%
We would see dead body and the body's would be stinking
Answer:
b) 50kg
Explanation:
You simply use F=ma equation, newtons second law
We are given: F=500N a=10m/s^2 m=?
1) lets change F=ma to help us find the m, we divide both sides with the a so we get 
2) plug in the F and the a,
, where 
3) plug it in ur calculator and you should get 50kg
hope this helped :)
