Helloyo!
Massive Star
They are typically greater then 8 molar masses. They typically have a quick main sequence phase, a short red supergiant phase and a death of a spectacular Cosmic event: Supernova. From there they can either become Neutron Stars or Black Holes
Medium-Sized Star
They usually have a Normal Main Sequence phase (Billions of years). From there they bevome Red Giants and expell their mass in a planetary nebula. From there they shrink and become white dwarfs first, then black dwarfs.
Hope it helps ya

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:
- 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.
- 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.
- Effector neuron: Its main function is to receive muscle stimuli capable of creating muscle contractions. These neurons are located in the spinal cord.
- 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.
