Easy Question. Will mark brainliest Sequence the steps of separating a mixture of sand, salt, and iron filings. Identify which physical property you were using in each step.

Mix the sand and salt mixture with water.
Physical property used:

Boil the salt and water mixture, leaving the salt behind.
Physical property used:

Separate the iron filings from the sand and salt by using a magnet.
Physical property used:

Use filtration to separate the sand from the salt and water.
Physical property used:

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
