Explanation:
A cell membrane is considered as selectively permeable because it controls or regulates the type of molecules that can pass through it. Substances of small molecules are allowed by the cell membrane while substances with large molecules are not allowed to pass through. For example , amino acids and simple sugar can easily pass through the cell membrane while protein and starch can't pass through it.
The cell membrane is considered or described to be boundary or border between the interior part and exterior part of the cell.

Explanation:
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.
