Answer:
Unable to be divided into further smaller pieces
Explanation:
This theory has been drawbacked by now but books still obey it.
Atoms can be divided further more into proton, neutron and electrons
Answer:
D
Explanation:
Its based on research but shows that it can be at a younger age as well
I just finished a topic in science on this.. lemme try my best:
4: PCR (Polymerase Chain Reaction)
5: Genetic Engineering
6: Restriction Enzymes (I think)
Let me know if I’m wrong!
Hello!
Chemical reactions require energy to begin. The reactants must collide with enough energy for bonds to change. This energy is known as activation energy - the difference in energy between that of the reactants and the amount needed for the reaction to occur.
Catalysts lower the activation energy needed for a chemical reaction to occur, therefore also increasing the rate of a reaction. Enzymes are proteins which act as catalysts within cells.
Therefore, enzymes cause the activation energy to lower.
Hope this helps!
