An organism that has two identical alleles (like two capital “T’s” or two lowercase “t’s” for example) is called

h, o, m, o, z, y, g, o, u, s

Explanation:

h, o, m o z y g o u s- T, T or t, t

H, e, t e r o z y g o u s- T, t

I put the commas there so it would let me submit, because it said I put bad words for some reason...

ANSWER WITHOUT THE COMMAS LOL

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
