Answer:
When an impulse reaches the muscle fibres of a motor unit, it stimulates a reaction in each sarcomere between the actin and myosin filaments. This reaction results in the start of a contraction and the sliding filament theory.
Hope this helps! :)
Green plants and certain other animals use a process called photosynthesis to convert light energy into chemical energy. Sunlight is the primary, non-recyclable, and easily accessible component of photosynthesis.
In the electromagnetic radiation that the Sun emits, sunlight is included. Water (H2O) and carbon dioxide (CO2) are ingested by plants during photosynthesis from the soil and atmosphere. In contrast to carbon dioxide, which is reduced within the plant cell and obtains electrons, water is oxidised within the cell of the plant. Due to this, carbon dioxide and water are converted into glucose and oxygen, respectively.
We can therefore conclude that green plants and some other animals convert light energy into chemical energy through a process known as photosynthesis. The most important, easily accessible, non-recyclable element in photosynthesis is sunlight.

Umm... If your talking about a bruise, then not usually, just be cautious of any radical changes in case of an infection, but a bruise is reasonable, seeing how it is trauma. If your talking about blood, then on occasion depending on your vantage point it may appear purple, don't worry it's just perspective.
