What is the relationship among cells, chromosomes, genes, and dna?
dna is a double-helix structure found in the cell nucleus. chromosomes straighten out the dna so the code can be read by genes.
cells contain chromosomes which are made up of genes. genes are made up of tightly wound strands of dna.
chromosomes are tightly wound strands of dna located in cells. genes are sections of dna.
tightly wound strands of chromosomes contain genes and are found in cells. the genes are coded sequences of nucleotides read by dna.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
