Answer:
Yes, chromosomes are in the nucleus of all cells that have a nucleus.
Explanation:
Zinc (Zn) always has a +2 charge. It is one of the exceptions.
The density of He is 1.79 x 10⁻⁴ g/mL
In other words in 1 mL there's 1.79 x 10⁻⁴ g of He.
To fill a volume of 6.3 L the mass of He required
= 1.79 x 10⁻⁴ g/mL * 6300 mL
= 11 277 * 10⁻⁴ g
Therefore mass of He required = 1.1277 g of He
The answer would be , a Chemical change!
The answer is D, because gems are usually not mettallic
