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.
- As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.
In conclusion, The new phages produced would have D) T4 protein and T4 DNA.

The answer is petiole. Hope this helps!!!
Answer:
According to the science magazine Scientific American, the sunset is reddish because, when the sun is setting, the light that reaches you has had to go through lots more atmosphere than when the sun is overhead, hence the only colour light that is not scattered away is the long wavelength light, the red.
