- keystone species is the correct answer.
<u>keystone species</u> which keeps the number of other animal population in
control and low in the entire ecosystem. They play an important role
through this process and helps the food chain effectively.
dominant species - most common species; found often in the ecosystem.
invasive species - which fights for itself survival and can cause harm to
ecosystem. non-native to an ecosystem
<span> For a start, when you have a question that needs answering in science, you formulate a null hypothesis. That is a negative statement which you then set out to prove or disprove. This is just a convention. So if your initial question is for example, "Does sugar dissolve in water?"
Your null hypothesis will be "Sugar does not dissolve in water."
You then set up your experiment and get some data.
Now if your data doesn't support your null hypothesis then you reject it and make the statement ,"Sugar does dissolve in water." As you can see from this simple example, a non-result is still a result so the idea of formulating new tests as mentioned by another answerer isn't necessary and in some ways is the incorrect thing to do. In science, hypotheses are often not supported by data and i would argue that this is the case a lot of the time. A non-result is still a result and you will have plenty to write about whichever way it goes. </span>
<span>No change in temperatures between seasons. Tilt is the angle between the direction of positive pole and the normal to the orbital plane. Seasons occur due to the tilt of axis. If there is no or zero degree tilt there will be no season. Season means changes in temperature. the amount of sunlight received remains same throughout the year which causes for no change in temperature and hence no season.</span>
Answer:
The correct answer is A they will no longer be able to perform aerobic respiration.
Explanation:
Rotenone is an isoflavonid compound which act an inhibitor of electron transport chain in mitochondria.Rotenone generally blocks the transfer of electrons from from NADH CoQ dehydrogenase or complex 1 to ubiquinone.
As electron transport is blocked the reduced coenzymes such as NADH,FADH2 are unable to be oxidized.
As a result cells exposed to rotenone will no longer be able to perform aerobic respiration.
