Carbon-14 dating primarily involves carbon-14 (¹⁴C) and carbon dioxide (CO₂). Living organisms absorb carbon from the atmosphere, including a small proportion of carbon-14. When they die, they stop taking in carbon, and the carbon-14 they contain begins to decay at a known rate, allowing scientists to estimate the time since death based on the remaining amount of carbon-14.
A mixture is made when several different substances are mixed together. Mixtures are combinations of two or more substances where the substances involved retain their chemical properties and can be separated through physical means.
The process of joining or separating two or more substances through a chemical reaction is known as a chemical change. During a chemical change, the substances involved undergo a transformation that alters their chemical composition, resulting in the formation of new substances. This can involve either the combination of reactants to form products or the breakdown of compounds into simpler substances.
Two is more stronger themselves
when two substances react a chemical change occurs
Two examples of solid substances are ice (solid water) and salt.
there are 4 kinds of dating: casual dating no feeling or emotion involved yet. special dating there a feeling involved and two person was promising to date. group dating dating with your friends or other person. blind dating there's a person or both of you arrange to know each other.
scientists use carbon14 and potassium argon to find absolute age of rock
In glycolysis, glucose is broken down into two molecules of pyruvate. The substances involved in glycolysis include glucose, ATP, NAD, and ADP. The end product of glycolysis is two molecules of pyruvate, along with a net gain of two ATP molecules and two NADH molecules.

A combination of different substances refers to a mixture where two or more substances are physically combined. This can include solutions, suspensions, colloids, or alloys, depending on the nature of the substances involved.
The two organs that produce substances involved in the digestion of lipids are the pancreas and the liver. The pancreas secretes pancreatic lipase, an enzyme that breaks down fats into fatty acids and glycerol. The liver produces bile, which is stored in the gallbladder and released into the small intestine to emulsify fats, aiding in their digestion and absorption. Together, these substances facilitate the efficient breakdown and utilization of dietary lipids.
The coefficients in a balanced equation represent the relative number of moles of each substance involved in a chemical reaction. By comparing the coefficients of the substances in the balanced equation, you can determine the mole ratios between them. This allows you to calculate the amounts of substances consumed or produced in the reaction.
The two structures that produce substances involved in the digestion of fat are the pancreas and the liver. The pancreas secretes digestive enzymes, including lipases, which break down fats into fatty acids and glycerol. The liver produces bile, stored in the gallbladder, which emulsifies fats, making them easier for lipases to act upon during digestion. Together, these substances facilitate the efficient breakdown and absorption of dietary fats in the small intestine.
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
