Answer:
a) produced the oxygen in the atmosphere
Explanation:
- Prokaryotes are likely to first form of life on earth and they existed billions of years ago before animals and plants.
- As these prokaryotes can do photosynthesis so there most important function is produce oxygen in atmosphere for the evolution of aerobic life.
- At that time the conditions were harsh on earth so these prokaryotes are used to survive under earth like in oceans. They first produce oxygen in oceans.
- In eukaryotes photosynthesis emerge by endosymbiosis with photosynthetic prokaryotes.
Answer:
This question is incomplete as it lacks options, however, it can be answered. The answer is:
CARBON DIOXIDE (CO2)
Explanation:
Cellular respiration is the process by which glucose is broken down in an organism's cell to release energy. Although the process involves series of reactions, however, the general equation is as follows;
C6H12O6 + 6O2 ➡ 6CO2 + 6H2O + energy
Based on the above equation, the inputs are glucose and oxygen while the outputs are carbon dioxide and water. Carbon dioxide (CO2) is the major byproduct of the respiration process.
C is the only bad sounding thing out of this bunch.
The nurse should assure the patient that black tongue is an expected side effect of taking that particular drug. The active ingredient in the drug contain bismuth. The tongue and the alimentary canal of humans contain trace amount of sulphur, when bismuth comes in contact with this sulphur, bismuth-sulphide will be formed. Bismuth-sulphide is an harmless by product, thus, the tongue discoloration observed in the patient is harmless.<span />
It is true that rivers and streams are biodiverse ecosystems that are sensitive to change. Details about rivers and streams can be found below.
<h3>What is river and stream?</h3>
A river is a large and often winding stream which drains a land mass, carrying water down from higher areas to a lower point, oftentimes ending in another body of water, such as an ocean or in an inland sea.
On the other hand, a stream is a small river or a body of moving water confined by banks.
Rivers and streams are both freshwater ecosystems, hence, tend to respond to changes in their environment caused by anthropogenic activities.
Therefore, it is true that rivers and streams are biodiverse ecosystems that are sensitive to change.
