Answer:

15 μM

Explanation:

From Figure 1 in the diagram showing the graphical representation:

We can see that the concentration of gossypol that reduced C. parvum growth to 50% is approximately 15 μM which lies between half the distance between 10 μM and 20 μM. The tracing is marked out and shown in the diagram attached below.

A bacterium is infected with an experimentally constructed bacteriophage

The complete question is:

a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have

A) T2 protein and T4 DNA

B) T2 protein and T2 DNA

C) a mixture of DNA and proteins of both phages.

D) T4 protein and T4 DNA

E) T4 protein and T2 DNA

A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.

A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.

The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria.

Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.
