Answer:
4. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen which catalyzes the decomposition of hydrogen peroxide to water and oxygen.
5. hydrogen peroxide
6. the reactant is hydrogen peroxide H2O2
7.the products are water and oxygen, H2O and O2
Explanation:
5. catalase breaks down two hydrogen peroxide molecules to form oxygen.
7. H2O2> H2O + O2 , catalase acts as a catalyst.
Answer:
The fossil record, however, is quite incomplete. Here's one major reason why: Sediment has to cover an organism's remains in order for the long fossilization process to begin. Most organisms decompose before this can happen.
If ocean currents were to stop, climate could change quite significantly, particularly in Europe and countries in the North Atlantic. In these countries, temperatures would drop, affecting humans as well as plants and animals. In turn, economies could also be affected, particularly those that involve agriculture.
Answer:
Photosynthesis produces glucose and oxygen. These are things that are needed by humans so that we can breathe, which is how humans make energy so 5hat we can do everyday things like walking and running. Without photosynthesis, the human race wouldn't be able to survive.
