Is this not about a human? We only have one aortic arch
Answer:
What if xylem were only located in the roots and stems, would fluids still move? No because xylem have stoma that enables transpiration to happen. If you remove xylem, you've removed that "vacuum" that pulls that water upward

Explanation:
An atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion (see page 10 for more on ions).
Answer
The nervous system has many more sensory fibers and sensory pathways than motor fibers. This stems from the importance of properly understanding the environment prior to responding. These ascending tracts provide the bridge between the inputs from the environment and the organizing centers of the brain that provide the complexity of our responses. Somatosensory systems include the receptors and pathways for transmission of sensory information from the soma to the portions of the brain that need to integrate it and act upon it. While much of this is conscious, there are also ascending systems that convey unconscious information involved in coordination (proprioception) and brain stem reflexes.
There are several different modalities that fall under the broad topic of "exteroception". These sensations include well-localized touch 2-point discrimination), light touch, pain, temperature and vibration sense. These sensations can be tested clinically. Proprioception is the ability to detect the position of the body in space. This may be consciously perceived, such as with joint position sense, or it may be a sensation that is not perceived consciously, such as from muscles and ligaments.
Conscious sensation
We will first discuss the pathways for conscious perception before considering unconscious sensation. These pathways for conscious somatic sensation, at their simplest, require three neurons (and two relay sites) from the periphery all the way to termination the cerebral cortex. These steps are often described as first, second and third order neurons in the sensory pathway. The signal can be modified at each of the relay points (nuclei).
Explanation:
The integumentary, immune lymph and endocrine system protects us from infectious microorganisms which is different from the the way your nervous, skeletal, and muscle systems does.
<h3>What are the protective systems of the body?</h3>
The protective systems of the body are those body system that helps protect the body against disease causing microorganisms. They include the following:
- Nervous: This system helps establish a network of communication between the various cells of the body.
- Skeletal: This system provides support through the bones for movement.
- Muscle systems: This system protects the vital organs of the body by absorbing shock and reducing friction in the joints.
There are other systems the protects the body which include:
- The integumentary system: This serves as a protective layer for the whole body.
- Immune system: This is made up of immune cells that help fight foreign bodies.
- Lymph: This is contains lymphocytes that fights disease causing microorganisms.
- Endocrine system: this contains hormones that control almost all body process.
