C. Organic matter this is a guess
Answer:
d. has acquired naked DNA from the environment
Explanation:
<em>Bacterial transformation is a process whereby a living bacterium takes up pieces of DNA from the environment and the foreign DNA becomes incorporated into the genome of the bacterium thereby 'transforming' it genetically. </em>
A transformed bacterium does not necessarily die within 48 hours, all other factors being considered.
Transformation does not hinder a bacterium from forming conjugation pilus.
Transformation does not always make a bacterium to be lethal to mouse. It depends on the gene present in the foreign DNA.
The correct option is d.
Answer:
B. active transport
Explanation:
When a substance is to be transported from the area of its lower concentration to the area of its higher concentration, energy is consumed. The process is called active transport as it uses energy to move molecules against the concentration gradient. Membrane transport proteins such as pumps are involved in this type of transport. Therefore, the given bacterium needs to use the process of active transport to absorb the nutrients from the surroundings.
