Answer:

b. 10 - 100 µL micropipetter

Explanation:

The micropipetters that would serve best to deliver 55 microliters would be the one which has a volume capacity of 10-100 µL.

This is because it will be easier to measure 55 micro liters from the Pipette which has a standard range of 10-100 microliter.

0.5 to 10 µL doesn’t fall within the range and it will be very hard measuring the volume.

Hello. This question is incomplete. You forgot to attach the image that completes the question.

The image is attached below:

Answer:

A- Sensory Neuron

B- Spinal cord

C- Effector neuron

D - Brain

Explanation:

  1. Sensory neuron: Its main function is to allow the reception of stimuli that are transformed into nervous impulses and electrical signals, capable of realizing sensations, such as a peliscão, for example. These impulses are transmitted to the spinal cord.
  2. Spinal cord: The main function is to support the body in an upright and vertical position. It also has the function of transmitting electrical signals and nerve impulses between some parts of the body and the brain.
  3. Effector neuron: Its main function is to receive muscle stimuli capable of creating muscle contractions. These neurons are located in the spinal cord.
  4. Brain: the processing center receives all the stimuli sent by the bone marrow. Its main function, in this case, is to produce bodily responses to the stimuli it has received, producing muscle movement.
