Answer:
Homogeneous - With a uniform appearance
Heterogeneous - With visible differences in the mixture
Explanation:
Referring to mixtures, homogeneous looks the same throughout, while heterogeneous has particles or whatnot.
Basically:
Homo means same
Hetero means different
Answer:
Substitution mutation
Explanation:
A substitution mutation is a type of mutation in which one or more nucleotide base is replaced by another in a sequence. This will result in the replacement of one or more amino acid in the amino acid sequence.
This is the case in this question where the original amino acid sequence was given as: Leucine – Alanine – Glycine – Leucine. After mutation, the following mutated sequence was produced: Leucine – Alanine – Valine – Leucine.
As illustrated above, one would notice that there is replacement of GLYCINE amino acid by VALINE in the mutated sequence, hence, it is an example of SUBSTITUTION MUTATION.
I would tell you... but there is a lot of information... just type in online what you asked, and you will get lots of info.

Explanation:
Given:
Number of atoms = 1.505 x 10²³
Let us solve for the number of moles and mass of this atom of sodium.
A mole of a substance is the amount of that substance that contains the avogadro's number of particles.
1 mole of Na = 6.02 x 10²³ atoms
Number of moles of Na = 
= 0.25moles
Mass of Na = number of moles x molar mass
Molar mass of Na = 23g/mole
Mass of Na = 0.25 x 23 = 5.75g
