Answer:
(3) 4 cm' and 2.0 g/cm3
Explanation:
Given:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³
Answer:
Among some of the numerical abnormalities a karyotype can detect are: Down syndrome (trisomy 21), in which an extra chromosome 21 causes distinctive facial features and intellectual disabilities. Edward syndrome (trisomy 18), in which the extra chromosome 18 translates to a high risk of death before the first birthday.
