Answer:
ANOTHER ANTIBODY MOLECULE OR A
Explanation:
I just know
Both use the scientific method to an extent and are a way of scientific exploration.
A salt is an ionic compound which needs a positive charge ion and a negative ion charge to form a salt.This means that the pair of element should be a metal and non-metal.This is simply because metal atoms tend to lose negative charge electrons and form positive ions while non-metals tend to receive the electrons from the metal atom to form negative charge ions.So answer is Cl and Li.
Answer:
C. Radioactive dating
I know this because radioactive dating is done by examining the atomic particles found in an object. The atomic particles decay over time at a predictable rate. Scientists are able to measure the rate of decay to establish the age of the fossil, organism, and/or material.
The experiment must be the same each time to get reliable results
