Answer:
The control group? (IDK)
Explanation: Isn't the control group the group that has all the factors that the experimental group has, except for the factor that's being changed?
Answer:
Calcium ions
Explanation:
The excitation-contraction coupling process is the process by which the electrical activation of muscles (the depolarization of the action potential) leads to the activation of contraction.
An action potential in the skeletal muscles or muscle excitation leads to Ca release from the sarcoplasmic reticulum via calcium channel protein. Released Ca regulates the contraction of the muscle.
The property is cohesion, I believe. It makes the molecules 'attract' to each other, and therefore, they move. However, adhesion makes water molecules stick to surfaces.
Answer:
Active transport necessary for the sodium-potassium pump to work because It allows sodium and potassium to move against their concentration gradient.
Explanation:
The transport of sodium ions outside the cell and potassium ions inside the cells is called active transport that requires the ATP hydrolysis. ATP provides the energy required for this procedure. This sodium-Potassium pump works to move the ions against their concentration gradient to keep the sodium concentration low inside the cells and potassium concentration high inside the cells.
