Well, a procedure tells you what to do in an experiment.
If a scientist does not carefully and accurately list the steps to performing the experiment, you will mess things up.
Hope this helps!
Answer:
The red one.
Explanation:
The red colour strands are the products of replication in which new DNA molecules are formed. The main purpose of replication is to produce extra set of DNA molecules for the new cell so that each cell receives extra molecules of DNA. Due to DNA replication, the cell has two types of DNA i.e. parent strands and new strands. The parent strands are blue in colour whereas the new strands are red in colour.
Answer:
Phosphorus cycles between living things and the soil.
Plants absorb phosphates from the soil and turn them into organic compounds through assimilation.
Animals eat plants and pass the phosphorus through the food chain from one animal to the other.
An animal dies and decomposes, returning the phosphorus to the soil.
Explanation:
Mass number = protons + neutrons
If you have the # of protons and the mass #, subtract the number of protons from the mass number to get the number of neutrons.
If you have the number of neutrons and the mass number, subtract the number of neutrons from the mass number to get the number of protons.
