Considering the carbon cycle, which of the choices would result if a large area of forest were burned?

baherus [9]

Fossil fuels represent carbon storage areas. Carbon that is locked in these fossil fuels does not cycle through the Earth. When humans burn fossil fuels, the stored carbon is released into the atmosphere as carbon dioxide. The carbon is then free to cycle through the Earth and can upset the natural balance of the carbon available, changing the way that processes occur on Earth.

Which of the following is a way that new DNA can be introduced to bacteria?

OLEGan [10]

Answer:

Explanation:

The correct answer here would be that it can be injected by a virus.

Since a virus operates by taking over the genetic system of the host and uses its replication, transcription, and translation to make virions or viral particles through the lytic or lysogenic life cycle. In the process, if the virus is utilized as a vector to carry a foreign DNA, the DNA is introduced into the genome of the bacteria. This is exactly what happens during the process known as transduction.

The correct option is, therefore, B.
