In nature there are many more variations amino acids than the simple 20 found in humans. However, when analyzing the human genome sequence, there is a code for all 64 permutations (4^3), only some of them share amino acids. This is a safe-guard against mutations of one or two nucleotides. For example, the amino acid Alanine is coded with four different nucleotide sequences: GCA, GCC, GCG, GCU. Also some amino acids code the same like UUU &UUC
Answer:
A. Cracks in rocks will deepen as the roots grow.
The amount of kinetic energy required for the molecules to break free of the intermolecular forced in the liquid is raised because the other ones don’t make sense
C.) a substance with a low ability to conduct energy
Explanation:
The statement that best defines insulators is that it is a substance that has low ability to conduct energy.
Insulators resist the movement of mostly electrical and thermal energy.
They have unique properties that makes them so.
- Insulators are substances that do not conduct heat and electricity.
- Both their solid and molten form lacks the capability of electrical and thermal conduction.
- Some substances can only conduct when molten or liquid.
- Conductors are materials that allows for the passage of electrical and heat energy.
- Most conductors are usually salts, ionic compounds and metals.
- Non-conductors like insulators are usually plastics and woods.

The given question is incomplete. The complete question is ;
Ammonia gas can be prepared by the following reaction:
In an experiment, 27.6 g of ammonia gas, 
, is produced when it was predicted that 50.2 g of would form.
What is the theoretical yield of ? What is the actual yeild of ? What is the percent yeild of ?
Answer: a) 50.2 g
b) 27.6 g
c) 5.0 %
Explanation:
a) Theoretical yield is defined as the amount of the product that is possible in the reaction.
Theoretical yield of = 50.2 g
b) Experimental or actual yield is defined as the amount of the product that is actually formed in the reaction.
Experimental yield of = 27.6 g
c) Percentage yield is defined as the ratio of experimental yileld to the theoretical yield in terms of percentage.
Hence percentage yield for the reaction is 55.0 %.
