Humans and mice differ because a. their cells have different small organic molecules. b. their cells make different types of large biological molecules. c. their cells make different types of lipids. d. their cells have some differences in the sequence of nucleotides in their nucleic acids. in) their cells make different types of proteins.

The answer is d.their cells have some differences in the sequence of nucleotides in their nucleic acids

Human and mice is both mammals and have similar structure and metabolism. There should be no big differences in biological or organic molecule. The big differences should be the sequence of the nucleic acids in their DNA. Mice could produce similar protein in human, but the DNA is different.

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
