Answer:
- allows fuels to burn forms
- is the gas that animals breathe
- forms ozone that absorbs the Sun's harmful rays
Explanation:
Oxygen is a powerful oxidizer (oxidizing agent or oxidant) that burns the fossil fuel, reacts with carbon, and produce CO2/CO. Although, it is not a sole oxidizer available on Earth but 99.9% of combustion reactions takes place in the presence of oxygen. It does the job by accepting electrons very fast in its valence shell.
Animals use oxygen to breath which produces ATPs through a series of chemical reactions particularly in electron transport chain. Again, it acts as a oxidizer and accepts electron in the electron transport chain. This gradient of electron flow is necessary for ATP production. In the end, water and CO2 are produced with ATPs.
Oxygen molecules in the stratosphere reacts with solar radiation (UV) and produce oxygen atoms. Thereon, each atom reacts further with the oxygen molecule to produce ozone. Ozone layer acts as a shield and doesn't allow penetration of harmful rays to the biosphere where living organisms are present.
It's going to be c.nerve cells
Answer:
I think it is adding catechol oxidase
Explanation:
This is because more enzymes are able to take in more substrates, or reactants more quickly, therefore increasing the speed of the reaction.

A) Phenotype is an organism's genetic makeup behind the scenes.
Answer:
C
Explanation:
The complete question: A student conducts an experiment to see how music affects plant growth. The student obtains four identical plants. Each one is potted in the same type of soil and receives the same amount of sunlight and water each day. Plant A listens to classical music for three hours each day. Plant B listens to rock music for three hours each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at all. In the experiment described in the scenario, which group represents the control group? A. Plant B B. Plant A C. Plant D D. Plant C?
<u>The control group here would be plant D.</u>
Control groups are usually used to minimize the effects of extraneous variables in the course of experiments and to ensure that the differences observed in different experimental groups are due to the effects of the independent variables.
<em>In this case, all the plants were exposed to music except the control group because the aim of the experiment is to measure the effects of music on plant growth. Any difference in growth observed between those exposed to music and the control group can reliably be considered to be due to the music.</em>
The correct option is C.
