Answer:
5
Explanation:
just subtract 20-25 and 5 is left over which is how much the water when up with the rock.
Density= mass/volume
16.39g/18.00mL = 0.9105 g/mL
Make sure to use the correct number of significant figures (4)
40.0 g ( 1 mole ) --------------- 6.02x10²³ molecules
? ? --------------------------- 2.90x10²² molecules
mass = 2.90x10²² * 40.0 / 6.02x10²³
mass = 1.16x10²⁴ / 6.02x10²³
mass = 1.9269 g
hope this helps!
Answer:
Crossing over Mitosis
Explanation:
A process called meiosis ensures siblings share just about 50% of their genotype. That's how siblings can have different DNA. Meiosis is a form of cell division that is only used to produce a special category of cells, called gametes.
