The nervous system and the muscle system respond to stimuli to produce motion. The skeletal movements of muscles are mostly voluntary.
Involuntary movements occur in these muscles when the nerve impulse passes from a sensory neuron to a motor neuron via an interneuron in the spinal cord.
<h3>What are Skeletal muscles?</h3>
Skeletal muscles may be defined as the muscles that fasten to your bones and authorize you to achieve a broad range of activities and operations.
Skeletal muscles control the direct movement of a person's will and are hence referred to as voluntary movement. While the spinal cord is associated with both movements directly or indirectly. It is a prolonged, delicate tubelike network liable for holding incoming and outgoing messages through the brain to the rest body.
Therefore, it is well described above.

Answer:
Is released into the air through stomata
Explanation:
Oxygen and hydrogen both exists as gaseous molecules in the atmosphere. However, one of them (oxygen) is a product of photosynthesis while the other (hydrogen) is one of the constituents of the molecule that starts the process of photosynthesis.
According to this question, the X used in the attached diagram is the role of oxygen in photosynthesis. Oxygen is released as a product of photosynthesis and goes out of the plant into the air via the STOMATA. Hence, the gas released into the air via stomata is OXYGEN.
Answer:
The use of music
Explanation:
<em>The independent variable in the example is the use of music.</em>
The independent variable in research or experiment is a variable whose value is not affected by any other variable. That is, the value of an independent variable is not influenced by any other variable.
<u>In this case, the use of music stands alone and is not influenced by any other variable in the experiment. In actual fact, the use of music's effect is being tested in the experiment and hence, is not in itself influenced by any other variable.</u>
Dichotomous key is a tool <span> - a series of questions and choices </span>that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish. The first step is observing the whole specimen you want to identify. Observing the habitat in which it is growing,its size and overall shape and some<span> distinguishing features. It is very important to make carefully these observations in order to use the key.</span>
Answer:
Both starch and cellulose are glucose polymers, but the glycosidic linkages in these two polymers differ, as shown in Figure 5.7. Glucose can have two slightly different ring structures. When glucose forms a ring, the hydroxyl group attached to the number 1 carbon is positioned either below (alpha)or above (beta) the plane of the ring. In starch, all the glucose monomers are in the alpha configuration (Figure 5.7b). In cellulose, all the glucose monomers are in the beta configuration. As a result, every other glucose monomer is "upside down" with respect to its neighbors (Figure 5.7c). The differing glycosidic linkages in starch and cellulose give the two molecules distinct three-dimensional shapes, leading to key functional differences.
