The answer is C. Photosynthesis.
I hope this helps.
Have a nice day. :)
The answer is D. Phospholipids are diglycerides (two fatty acid chains covalently bonded to a glycerol molecule)
that are covalently bonded to a phosphate group by an ester linkage. Fatty
acids are long chains that are mostly made up of hydrogen and carbon, while
phosphate groups consist of a phosphorus molecule with four oxygen molecules
attached. Glycerol is a 3 carbon chain containing hydroxyl groups in each of the carbon.
Because is is giving you an directon of somewhere and if it moved it will locate a different location.
Answer:
A) one intermediate band
Explanation:
Meselson & Stahl experiment on the E.coli bacteria to identify the mechanism of replication in bacteria.
For this, they grew bacteria in a heavy isotope of the nitrogen ¹⁵N which allowed the bacteria to take ¹⁵N in their DNA. They then grew the bacteria into ¹⁴N which allowed the bacteria now to take ¹⁴N in their DNA.
When they allowed the bacterial population to replicate their genome for one generation they found that their genome contained both types of isotopes of nitrogen in their DNA through centrifugation.
Since after the centrifugation only one band was observed which contains both the form of the nitrogen, therefore, the band was called intermediate band with intermediate density.
Thus, Option-A is the correct answer.
