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.
Answer:
Explanation:
You can't award 20 points once you have awarded 5.
One
2K + Cl2 ==> 2KCl
It's True
There are 2 Ks and Cl2 has 2 atoms making up on the left.
On the right, 1 molecule of KCl has 1 Potassium and 1 Cl. But there are 2 molecules so between the two of them, there's 2 Potassiums and 2 Cl
Two
The reactant side is the Left side. Cl2 means there are 2 Cl atoms making Cl2. Answer B
Three
False: There are 2 but read below.
I really don't know how to answer that. It's not qualified enough. There are a total of 2 Chlorines on the right hand side when there are 2 molecules. I think you are intended to answer False, but don't be surprised if you get it wrong.
Answer:
A, B, C and D
Explanation:
It can result for all of the choices mentioned.
Answer:
10 nitrogens
Explanation:
The 2 is the number of nitrogens in a molecule of N2. There are 2 of them.
The 5 is a whole different critter. It tells you that it was part of an equation and it took 5 molecules of Nitrogen to balance the equation. You only see numbers to the right of a molecule when the molecule is in an equation.
5 (2)=10
