Answer:
Sarcomere
Explanation:
The sarcomere is the smallest contractile unit of muscle. It extends from one Z disc to the next and therefore, is the region between two consecutive Z discs. It contains an A band flanked by half an I band at each end. Contraction of a muscle fiber occurs as the sarcomeres within the myofibrils shorten. During the shortening of the sarcomere, the thin actin filaments slide past the thick myosin filaments and approach one another. The resultant shortening of the I band and complete disappearance of H zone cause contraction of muscle fiber.

The process is known as transpiration or in the hydrologic cycle evapotranspiration as water exits the plant body in the form of vapor or droplets. This helps the plant to cool its body and also helps to available for the atmosphere again in pure form. It
Answer:
Perfectly cube - shaped
Explanation:
If the shape of a cell is perfectly cube- shape then its volume must be calculated with an equation:
Height×Width×number of sides and number of boxes
Surface= area of volume ratio is calculated with an equation
Area /volume
if a cell has large surface area to volume into ratio means it has greater exposure to the environment.It means that flow of nutrients and gases move freely in the small cell compared to large cell.
