The muscles are composed inside mainly of fibers, filaments and proteins, where it is important to consider the <u>length-tension</u> relationship of the thick and thin filaments to know the tension.
<h3>What is muscle contraction?</h3>
It is an organized and natural event that takes place at the level of the muscles when the fibers and proteins inside them come together, and tension is produced in the area.
<h3>Characteristics of muscle contraction</h3>
- In a muscle contraction, a tension is generated that depends on the length-tension relationship, which causes a displacement of the muscle filaments.
- The proteins actin and myosin join together, and a force is generated so that the final movement is achieved.
- To know the tension, the muscle changes length and measurable external work is produced from the force and distance traveled.
Therefore, we can conclude that the contraction allows us to make movements to reach and carry our extremities to different places.

Answer:
Polar
Explanation:
A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons. The hydrogen atoms have one electron each.
The chemical formula C6H12O6 is the chemical formula of glucose which is a monosaccharide containing an aldehyde group (-CHO) with 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms. Glucose is a product produced from photosynthesis.
The chemical molecular formula for the photosynthesis process is 6CO2+6H2O→C6H12O6+6O2. The synthesis process is a reaction that occurs in plants to produce food to be used as energy for cells. The process of photosynthesis requires materials in the form of air which is represented by H2O and carbon dioxide which is represented by the formula CO2 in the chemical formula of the photosynthesis process. The products of photosynthesis are glucose which is represented by C6H12O6 and oxygen which is represented by O2 in the chemical formula.
Some people often refer to the chemical formula of photosynthesis as CO2+H2O→C6H12O6+O2, this formula is an unbalanced equation. Because the auction will produce glucose with the chemical formula C6H12O6 having 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms, then should the chemical formula carbon dioxide H2O and water O2 also have a total of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.
