Complete question:

Drag each tile to the correct box.

Lucia is walking barefoot in her yard. She accidentally steps on a nail. How will her nervous system work to generate a reaction? Arrange the events chronologically.

  1. Interneurons relay the impulse to motor neurons in the spinal cord.
  2. She immediately moves her foot.
  3. The sensory neuron generates an impulse.
  4. Receptors in her toe receive stimuli.
  5. Motor neurons signal the leg muscles.

Answer:

4. Receptors in her toe receive stimuli

3. The sensory neuron generates an impulse.  

1. Interneurons relay the impulse to motor neurons in the spinal cord.

5. Motor neuron signal the leg muscles    

2. She immediately moves her foot.  

Explanation:

The reflex arc refers to an action mechanism that responds to different stimuli.  It is an involuntary reaction involving different nervous vias. The reflex arc is composed of receptors, afferent nervous fibers, efferent nervous fibers, and effectors.    

Receptors are located in nervous terminals and are widely distributed in the organism. Receptors are capable of receiving stimuli from different nature, and most of them are specialized in one kind of stimuli such as vision, audition, touch, among others. In the exposed example, these sensory receptors were located in the toe, and probably they were touch receptors.

When they receive the stimulus the sensory neuron transforms it into an excitatory nervous impulse that goes to the central nervous system along the afferent nerves. This stage is known as the <u>afferent via</u>, beginning with the environmental information received by sensory receptors, and ending in the arrival of the transcripted message to the central nervous system.

When the central nervous system receives the information, it processes it and sends an appropriate answer according to the stimulus. The message goes along the interneurons to the motor fibers, which are in charge of taking that answer to its destiny, the effectors. Effectors are usually muscles or glands, and they transform the received impulse into a motor answer that executes the reflex action. In the exposed example, the effector in the muscle. This stage is known as the <u>efferent via</u>, beginning in the central nervous system sending an answer impulse and ending in the effector (muscle) executing the answer.

7. a) How does a vaccine relate to the virus that it protects against? (1 point)
valentina_108 [34]

Answer: A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria.

Answer:

Where hot rock nucleates at the core-mantle boundary and rises through the Earth's mantle becoming a diapir in the Earth's crust.

Explanation:

I think that this is right...

-Google

____________________________________________________________

Diapir- a domed rock formation in which a core of rock has moved upward to pierce the overlying strata.

Core-mantle boundary- The core–mantle boundary of the Earth lies between the planet's silicate mantle and its liquid iron-nickel outer core.
