They would have concluded that the protein coat also entered the bacterial cell and could not deduce that protein is the genetic material.

Explanation:

In their experiment, Hershey and chase found that all the DNA coated with 32 p were missing from the solution as bacteriophage after adsorption on bacterial cell their DNA was transferred to the bacterial cell. The presence of 32 S in the solution shows that the protein coat does not enter the cell during infection.

This way they concluded that DNA is the genetic material and not the protein.

Since phage infecting bacteria inserted their DNA into it and got replicated increasing their number. Also, protein is not involved in their growing numbers.

Hershey and chase have concluded that DNA is not protein it was the genetic material.

Explanation:

Hershey and chase said that DNA is not protein it was the genetic material. They took a direct physical approach in finding the genetic material. They both determined that a protective coat was formed around the bacteriophage.

The internal DNA is not a protein, a genetic material. They used label to find it. The lack of 32p labeled DNA remaining in solution after bacteriohages are allowed to absorb the bacteria showed tha DNA was transferred into the bacterial cell.

The radioactive 35s in the solution shows that protein coat protects the DNA before adsorption.

What does a plant need to create a glucose molecule in photosynthesis?
DerKrebs [107]

Answer: 1 glucose

Explanation: Basically, in photosynthesis, energy from light is used to convert carbon dioxide and water into glucose and oxygen. For 6 carbon dioxide and 6 water molecules, 1 glucose molecule and 6 oxygen molecules are produced. So your answer is 1 glucose. BTW, I got my answer from Google and from the website called thoughtco    Go check it out!

Arrange the three kinds of nitrogenous wastes based on the energy required to synthesize them, beginning with the waste product
Evgen [1.6K]

the three kinds of nitrogenous wastes based on the energy required to synthesize them are arranged; Ammonia < urea < uric acid.

Nitrogenous wastes are the nitrogen compounds that organisms use to get rid of excess nitrogen. Ammonia, urea, and uric acid are the most common nitrogenous wastes that animals excrete. Protein metabolism generates all of these nitrogenous wastes.

Ammonia is the most toxic of these nitrogenous wastes, and it is the most common but requires the least energy. Urea is more harmful than uric acid, but it is less harmful than ammonia, reducing the amount of energy required to synthesize it. Uric acid is the least harmful, a non-poisonous particle with four nitrogen molecules. This is useful for birds and reptiles that lay hard eggs because it eliminates the most nitrogen, uses the least amount of water, and is not toxic. It also takes the most energy input.
