Answer:
a. Cell wall and chloroplasts
Explanation:
The cell wall in plants facilitates the retention of the cell shape during over-hydration. The chloroplasts are organelles in plants that carry-out photosynthesis and produce glucose.
One ribose molecule are found in ATP.
Develop plants that are unable to reproduce
By producing sterile plants, the scientists may observe the effect of their presence on the ecosystem without the risk of the plants reproducing too quickly to be controlled. If the plant does not act as an invasive specie and is promoting the ecosystem in which it is placed, non-sterile varieties of the plant may be developed. However, if the plant seems to have an overbearing competitive advantage and is easily over taking the other species' resources, it should not be introduced.
#11.) Phacops. It lived in the late Devonian Period (~400 million years ago).
#12.) Carbon-14 is a good radioactive isotope for determing the age of artifacts from a burial site thought to be associated with the most recent early humans because it is present in all organic matter (which humans have, of course).
#13.) 3, Devonian.
#14.) From the Devonian Period through the Triassic Period.
#15.) Cenozoic.
According to the research, the correct option is photosynthesis. The process of <u>photosynthesis</u> generates the oxygen that we breathe and the food that we eat.
<h3>What is photosynthesis?</h3>
It is the process of obtaining energy from plants, algae and certain bacteria to synthesize organic substances from other inorganic ones.
This metabolic process carried out by some cells of autotrophic organisms is essential for life since, starting from light and inorganic matter, it manages to synthesize organic matter and allows carbon dioxide (CO2) to be fixed from the atmosphere and oxygen to be released.
Therefore, we can conclude that according to the research, the correct option is photosynthesis. The process of <u>photosynthesis</u> generates the oxygen that we breathe and the food that we eat.
