Answer:
A) stratified
Explanation:
Total call including 6500 'yes' and 4100 'no' are 10600 and on each call there was a fifty cent charge. Total charge becomes 5300 $ so this is very straight forward data. And from this test two types of classes are made with cleared population in each class and such cleared population division is example of stratified sampling so this is right answer.
Answer: mercury and venus are (closer to) the sun than earth is. so their orbital periods are (shorter) than earths orbit. the further a planet is from the sun the (longer) it’s orbit is.
Explanation:
The labels are not found here but allele frequencies depend on the number of different gene variants in a given population.
<h3>What is an allele?</h3>
An allele is a given gene variant received from parents, which is found in a specific gene locus in a chromosome.
Allele frequency makes reference to the number of that a given gene variant or allele exhibits in a population or sample.
In conclusion, the labels are not found here but allele frequencies depend on the number of different gene variants in a given population.

Your answer to fill in the blank should be "interactions"
The following are true of mole ratio
- They are expressed as ratio of mass to molar mass
- It is measured in moles
<h3>How to calculate the mole ratio</h3>
The formula for calculating the mole ratio is expressed according to the formula shown:
Mole ratio is the ratio of the mass of a substance to the molar mass of the same substance.
To calculate the mole ratio
Mole = Mass(g)/molar mass(g/mol)
Hence the following are true of mole ratio
- They are expressed as ratio of mass to molar mass
- It is measured in moles
