Precise but not accurate,the real temperature inside the refrigerator is 37 degrees C. The thermometer isn’t accurate (it’s almost two degrees off the true value), but as the numbers are all close to 39.2, it is precise.
Answer:
Scourge
Explanation:
Scourge is something or someone that causes suffering. It can be in the physical sense like pain and torture, or it can be in the form of emotional and psychological pain. Scourge is not limited to physical beings or things, it can also be events or situations like droughts, diseases, earthquakes.
Answer:
The correct answer will be option-E
Explanation:
Hershey and Chase's experiment was performed to test whether DNA serves as the genetic material or protein.
To perform experiment they grew bacteriophage into radiolabeled phosphorus and sulfur compounds. The phosphorus is an integral part of the structure of DNA whereas proteins contain sulfur in their structure.
In the given condition if radiolabeled nitrogen is utilized then the experiment will fail as the structure of proteins also contains an amino group( NH₂) in their structure as well as DNA. The scientist will not be able to identify whether the DNA is the genetic material or protein.
Thus, option-E is the correct answer.
I think it's Photosynthesis because photosynthetic bacteria began producing excess oxygen, which added oxygen to the Earth's atmosphere.
A mutation occurs when there are changes in the gene structure of organisms. It may either increase or decrease the fitness of organisms. However, for mutations to be evident in an organism, it must be inherited by the offspring.
On the other hand, genetic recombination occurs during the sexual reproduction of two parents. During this process, different gene combinations or genotypes are produced. This event is similar to shuffling a deck of cards.
Lateral gene transfer occurs when the genetic material is transferred between organisms. This is not the same as transferring the genes from parent to offspring. This process usually occurs in single-celled organisms such as bacteria and plasmids.
