Alai records data about making a mixture of salt and water.

which best explains why alai’s salt measurement is wrong?

it should be recorded in milligrams.
it should be recorded in millimeters.
it should be recorded in centiliters.
it should be recorded in centimeters.

The correct answer is A. It should be recorded in milligrams

Explanation:

In an experiment, one of the most important elements is the units used to measure substances, because these are different depending on the substance, and the purpose of the experiment.

In the case presented, it is correct Alai decided to use milliliters to measure the volume of water because the milliliter (mL) is a unit that measures the volume of liquids. However, he cannot use milliliters to measure the mass of salt because milliliters measure volume rather than mass. Instead, he should use milligrams as this measure mass of the substance and similar to milliliters is appropriate for small quantities of a substance. Thus, Alai's salt measurement is wrong because it should be recorded in milligrams.

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.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
