Answer:

The fact that only DNA of the Bacteriophages entered the host cell.

Explanation:

At the time of the experiment, scientists debated whether DNA or proteins were the genetic material. Many thought that DNA was simply used to store phosphorus because it was encased within the nucleus and was not a very active molecule. Hershey and Chase showed that when a bacteriophage virus infects a bacterial cell, only the DNA is injected into the cell while the protein case remains outside. This proved that DNA and not proteins was the genetic material.

"Tryptophan self-controls its synthesis." Justify this statement.
miskamm [114]
Just say we have a big amount of tryptophan in the sense that it exceeds, tryptophan would act as a co-repressor which prevents synthesis of more enzymes for its production

Hope this helps :)

olya-2409 [2.1K]
Given that an average human has a heart rate of 70 beats per minute and if one is to have a 70 year life span, the number of times it will beat is 2,575,440,000 times. This was computed by multiply 70 years by 365 days/year x 24 hours/day x 60 minutes/hour x 70 beats/min. Thus, the heart will beat numerous times before it finally stops.

For number 1 the first arrow is the cell wall, the second is the membrane, and the last arrow would be the cytoplasm
For number 2 they are in distilled water Bc they are remaining the same and not shrinking up
For three draw the cells smaller salt water sucks the water out of them
For four they get smaller because the salt has a higher concentration making the water leave the cell. Once water has left the cell begins to shrink
