When determining the exact age of a rock or fossil, scientists most commonly use a method known as Radiometric dating. This aging method works because by A. Comparing the age of the fossil against the age of other nearby rocks
B. Comparing the amount of a known radioactive element against the known stable daughter element
C. Comparing the amount of bacteria and other organisms present against those elsewhere
D. Using radio waves to Measure the exact depth of the rock or fossil and determining how long it would take to be buried that deep

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.
