Answer:
D. energy produced by splitting molecules
Explanation:
Only urchins were removed, which resulted in an increase in limpet population and decrease in seaweed cover.
- Sea urchins and limpets both consume seaweed, making them competitors for it. The limpet population grows as a result of the urchin removal, having a greater impact on the amount of seaweed present.
- The biodiversity of these settings can be wiped out if seaweed builds up in bodies of water. This issue arises when there is an overabundance of algae, which, in search of additional food, proliferate aggressively and cause pollution.
- Additionally, life might end where there is pollution. Hedgehogs and limpets can play a significant role in this situation because they feed on seaweed, which helps to control the problem of its excessive profusion.
- A lot of research has been done to determine the value of these two species in preventing pollution brought on by the growth of seaweed.
- When the sea urchins and limpets were removed in the study mentioned in the question above, seaweed cover rose significantly more than when only the sea urchins were removed.
- This most likely occurred because the limpet population expanded and the amount of seaweed was reduced when only the hedgehogs were eliminated.

Oxygen is required for aerobic respiration. This reaction produces ATP (universal currency for energy) which our bodies use to survive. Without oxygen much less ATP is produced, as aerobic respiration cannot occur in the lack of oxygen. ATP can be formed by anaerobic respiration, in the lack of oxygen, but this produces far far fewer molecules of ATP. This also produces lactic acid causing us to become fatigued and tired. Thus oxygen is crucial to produce the maximum amount of ATP possible.
Glucose is the main molecule which is respired by our bodies to produce ATP/ energy, which our bodies use to survive. Oxygen and glucose react in the mitochondria to make ATP (release energy.) It therefore, is called a respiratory substrate.
Note: I'm avoided talking about the exact phases of respiration as it is usually not covered till college/ A level standards. If you would like to know exactly which reaction requires oxygen and how it's used (i.e. the stages of respiration) don't hesitate to ask.
Answer:
There is no control.
Explanation:
If the scientist was testing something based on the different temperatures, they would need the amount of time in the oven to be the same for each cookie so that they can compare them. Without the times being the same, the scientist would not be able to tell whether the temperature or the time in the oven caused the differences in the cookies.
<span> A virus is not a living thing so antibiotics, intended to kill living things, are not effective. A virus cannot multiply outside a living host cell. There is no treatment for a virus, just supportive therapy. The body will fight off most viruses over the course of time. Vaccines do not cure viruses, so the only way to protect your goat from viruses is through specific vaccines.
So the answer is a virus</span>
