Chromosomes are composed of two types of biomolecules. One of the biomolecules in chromosomes is called DNA, which functions as the genetic code. The other biomolecules in chromosomes are called histones, which bind the DNA tightly for cell division. Genes in DNA have the code for making histones. Based on the information above, which types of biomolecules are in chromosomes? F Carbohydrates and lipids
G Proteins and nucleic acids
H Proteins and carbohydrates
J Nucleic acids and carbohydrates cationTM Inc​

proteins and nucleic acids

histones are proteins and DNA is made up of nucleic acids (these are the macromolecules made up of nucleotides)

Explanation:

B

Explanation:

a plant living in a dry region means it will need to have less stomata on the upper surface of the leaf than the bottom to save as much water as possible since a more drier region lacks water, so look for a plant that has the least number of stomata on the upper surface - B

it has no stomata on the upper surface of the leaf which means less water loss through the stomata via transpiration
