The answer is a. to determine what sort of data table will be most useful.

Controlled experiment is used parallel with experiment in which some alteration of the subject is induced. This is because this way can be compared in treated and non-treated subject. When sort of data table is necessary, using the controlled experiment, it can be determined what sort of data table will be most <span>useful.</span>

const2013 [10]
The data given are 
            melting point            density 
<span>Zinc        419.53 oC              7.134
Nickel      1455oC                 8.912
Copper  1084.62oC              8.96
Silver        961.78oC           10.501
Gold        1064.18oC          19.282

density is the mass per unit volume. Melting point is determined by the intermolecular forces between particles in the solids.
We </span>have been asked to find which cube weighs the most 
density = mass/volume 
when volume is constant for all the metals, then density is directly proportional to mass. Therefore metal with highest density has the highest mass.
from the given metals, metal with highest density is Gold.
correct answer is Gold.

AlekseyPX

Answer:

GUA and GUG.

Explanation:

If you look at the attached genetic code, the wild-type glutamic acid (Glu) is coded by the codons GAA and GAG.

Valine (Val) can be coded by the codons GUU, GUC, GUA or GUG.

Sickle-cell hemoglobin arises from a single mutation, which causes the translation of Val instead of Glu. The only codons that code for Valine that differ in just one base with the Glu codons are GUA and GUG.
