The density of a population of living organisms is usually measured in individuals on one square km. In here we have 50 earthworms on an area of 5 square meters, thus we have 10 earthworms on every square meter. In order to get to the result we need to see first how many square meters there are in one square km. One square km has one thousand meters of length and one thousand meters of width so:
1,000 x 1,000 = 1,000,000 km²
Since we established that we have 10 earthworms on every one square meter, we just need to multiply the number of square meters with the amount of earthworms on every square meter:
1,000,000 x 10 = 10,000,000
So we have a density of 10 million earthworms per square km.

DNA is like a blueprint telling enzymes and acids like RNA and mRNA what to do with its "code." The first option is not correct because the situation is actually vice versa. Chromosomes are made up of DNA and proteins; DNA is not made up of chromosomes and proteins. There are 23 pairs of chromosomes in the human cell. In that cell there is also DNA and ribosomes that make up proteins. Option three is not entirely true because, well, if the option is referring to the process of transcription, then it is mRNA that translated DNA's code not RNA's. The fourth option is also wrong because alleles are located in parts of chromosomes. Thus, the second option is the correct option because the option both makes sense and is what DNA contains.
