Answer: photoautotrophs
Explanation:
Photosynthetic organism are called photoautotrophs this is because they have the ability to produce there own food using CO2 and H20 and energy from sunlight to generate glucose and oxygen.
Heterotrophs who do not produce there food depends on them and other organic sources for their food.
Example of photoautotrophs include, Algea,plant,bacteria,Euglena.
Answer:
The intermediate density band is observed.
Explanation:
Messelson and Sthal's explained the model of semi conservative nature of DNA replication. According to this model, the newly synthesized DNA molecule contains one newly synthesized strand and one parental strand.
Firstly, bacteria grown in 15N media is transferred to 14N media. The isolated DNA is centrifuged and intermediate density DNA band is observed that contains one strand of 15N (parental strand) and one strand of 14N (newly synthesized strand).
Explanation:
Molecular biology is a branch of biology that concerns the molecular basis of biological activity between biomolecules in the various systems of a cell, including the interactions between DNA, RNA, proteins and their biosynthesis, as well as the regulation of these interactions.
Answer:
I would have to say recharge of the aquifer by using ground water after some precipitation.
Explanation:
Melting snow or rain increases ground water that percolates down to replenish the aquifer.
Elevation changes causes the aquifer to flow up in low spots/springs on the surface. And the cycle repeats through evaporation and plant respiration.
Answer:
Oxygen
Explanation:
During photosynthesis, oxygen is released. I found this from a quizlet.
