Answer:
The correct option is <em>D. Hershey and Chase</em>
Explanation:
Experiments carried on by Hershey and Chase proved that DNA is the genetic material. It discarded the former belief that proteins were the genetic material.
Hershey and Chase carried out their experiments by using radioisotope of phosphorus (32P) and sulphur (35S) to prove their point. Phosphorus is present only in DNA whereas sulphur is present in proteins but absent in DNA. Hence, the usage of these isotopes acted as radioactive markers to prove the results of their experiments.
In order to move molecules against the concentration gradients, the cell must have the advantage of Creates energy
<u>Explanation:</u>
When a solute is concentrated to a particular area it is called as concentration gradient. The law of thermodynamics well explains that a molecule moves from area of higher concentration to lower concentration.
If a molecule moves against the concentration gradient it is called as Active transport. For this process to happen the cell needs to energy efficient.
Energy is been released and it is stored in the form of bonds between the atoms during active transport. To maintain the proper balance in the molecules and the balancing of ions active transport is essential.
Answer: The United States and Morocco are parts of different plates. The plates slowly moved far apart as soft, solid rock from underneath got added to the edges of the plates over millions of years.
Explanation:
I’m pretty sure this is right
The thermosphere is the layer in the Earths atmosphere directly above the mesosphere and below the exosphere. Within the layer of atmosphere, ultraviolet radiation causes photoionization of molecules creating ions the thermosphere continues the larger part of the Ionosphere.
