Because they are in different galaxies. I hope this helps! :)
It's a prokaryotic cell type.
<u>Answer</u>:
Substance A affects the amount of the activation energy needed by the process by catalyzing the reaction. Enzymes are the natural biological catalyst that lowers the activation energy for a reaction to proceed faster at a low energy requirement.
<u>Explanation</u>:
The reactants in the solution react to form a product. For a reaction to happen some energy is needed. The energy which helps reactants to break some bonds and make other bonds to make a product is known as activation energy.
Enzymes are the biological molecules which lower this activation energy by catalyzing the reaction by helping in breaking old bonds and forming new bonds to create a product.
Your answer would be true.
Answer:
The correct option is A. Cooler, more dense material sink while warmer, less dense material rises.
Explanation:
Convection can simply be described as the transfer of heat energy among molecules or substances. Convection will occur if molecules of liquid or gas are given rough supply of heat. Hot liquids or gases would have the following properties:
- Their density would be less.
- They would have the ability to rise.
Whereas the cooler molecules will have the following properties:
- Their density would be more than the hot molecules.
- They would have the ability to sink.
