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.
<span>The temporal lobes is a portion of the cerebral cortex
that is most closely adjacent to the ears. Its function is a responsible for
processing auditory information from the ears (hearing). It is mainly revolves
around hearing and selective listening and receives sensory information such as
sounds and speech from the ears. Furthermore, it is also a key to being able to
comprehend or understand meaningful speech. Thus, we would not be able to
understand someone talking to us if it wasn’t for the temporal lobe. Lastly,
this love is special because it makes sense of all different sounds and pitches
that is being transmitted from the sensory receptors of the ears. </span>
