Answer:
Griffith concluded that the R-strain bacteria must have taken up what he called a "transforming principle" from the heat-killed S bacteria, which allowed them to "transform" into smooth-coated bacteria and become virulent.
Explanation:
Answer:
Population growth, lack of supplies
Explanation:
Urbanization can impact an area, especially population growth. People could be crowded, and that supplies could run out as it is an urbanized region.
Answer:
A light pole

A hydrothermal vent contain many bacterias which can survive under those conditions, similar to an abandoned mine
The Kowloon Walled City can be considered an ecosystem only because within the City there may be many areas in which an organism could inhabit
Answer:
The options
A) T-series bacteriophages
B) retroviruses that require a DNA intermediate
C) single-stranded DNA viruses such as herpesviruses
D) nonenveloped double-stranded RNA viruses
E) linear double-stranded DNA viruses such as adenovirus
The correct answer is B.
B) retroviruses that require a DNA intermediate
Explanation:
Since the baltimore's scheme which was used for virus classifications was included, the most closely likely alternative of virus to the given polio virus that possess a single stranded RNA in these case study is more likely to be retroviruses that needs a DNA intermediate.
Unlike the single-stranded RNA viruses, the retroviruses lack DNA but possess the enzyme called reverse transcriptase used for RNA replication into the host cells DNA and take advantage of the end product for their favour.
I hope this answer helps.
