They build up in the thylakoid, where they bond to each other to create ATP.

Answer:
a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants it consists mainly of cellulose.
Explanation:
C. when recycling, people can re-use the material/products.
Answer: The concentration of calcium in the myofibril must decrease.
Explanation:s soon as the stimulus which causes myofibril to contract stops, its time for muscle to relax.
A low calcium level in the protoplasm is the utmost requirement of muscle relaxation otherwise sliding of myosin will continue and muscle will keep on showing contraction. In order for muscle contraction, calcium ion i.e. Ca²⁺ must come out of the protoplasmic reticulum so for relaxation reverse process occurs i.e. Ca²⁺ is pushed back to the protoplasmic reticulum. There are many pumps known as "calcium pumps" which facilitate this process. Now, the concentration of Ca²⁺ becomes comparatively low in the protoplasm which causes troponin C to detach from Ca²⁺. Their detachment causes actin and myosin to detach from each other too which finally leads to muscle relaxation.
<span>In the six kingdom classification system bacteria are divided into two kingdoms which are known as Archaebacteria and Eubacteria. The archaebacteria are organisms that can dwell in hostile environments like deep sea vents, hot springs, and salt water; while Eubacteria include organisms that can be harmful to humans because they cause certain kinds of diseases like step-throat and botulism.</span>
