Answer:
48g
Explanation:
Volume of rock=16cm^3 (1 ml=1 cm^3)
Density=3 g/cm^3
Mass=?
d=m/v
3g/cm^3=m/16cm^3
3g/cm^3*16cm^3 =m
Therefore, m= 48g

-Disruptive selection
Disruptive selection results in the creation of two distinct phenotypes.
Explanation;
-Disruptive selection is a type of natural selection that selects against the average individual in a population. The make up of this type of population would show phenotypes of both extremes but have very few individuals in the middle.
