The correct answer is '<span> balance consumption of food with use and storage of nutrients </span>'. All animals can only survive if the amount of food consumed is equal to or greater than that required for growth and respiration. Most animals have adapted to be able to store excess food (such as fat) during times of plenty, to be able to survive when there is insufficient food available.
Answer:
Identity Diffusion
Explanation:
A person whose identity status is Diffusion has not had an identity crisis and has not yet fully realized their social identity or personal traits. Moreover, this person is not seeking to make a commitment to establish his or her identity. It is almost like identity Foreclosure; however, in that stage, the person adopts some traits and qualities of friends and parents.
<em>Hypotonic solutions contain a low concentration of solute relative to another solution ( The cells cytoplsm) </em>
<u>Thus, when a cell in placed in a hypotonic solution, the water diffuses into the cell, which causes the cell to swell up. </u>
<em>The cell has lower solute concentration than the solution. So the solution is HYPERTONIC and the cell is HYPOTONIC. </em>
As a result, a cell that does not have a rigid cell wall, such as a red blood cell, t'will most definitely swell and burst when placed in a hypotonic solution.
Answer:
d. the movement of myosin head while attached to actin myofilament
Explanation:
During muscle contraction, the calcium ions released from the sarcoplasmic reticulum in the sarcoplasm bind to troponin which in turn removes tropomyosin from the myosin-binding sites present on the actin. Hydrolysis of ATP at the myosin heads energize them. These myosin heads with stored energy bind to the myosin-binding sites on the actin filaments. In their bound conditions on the actin filaments, myosin heads are called cross bridges. Only one myosin head of a single myosin molecule forms cross-bridge at a time.
