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 law of conservation of energy states that the Total Energy in a system will remain constant in an isolated system. Energy can only transfer. The law of conservation also states that energy can neither be created nor destroyed and that is a ambit concept in physics.
Some examples:
When a person eats, their bodies will convert chemical energy from food into mechanical and electrical energy so that the person can move.
Use an example of any machine, for example:
A blender transforms electrical energy into mechanical energy
Answer:
Plants cells do not have lysosomes
Answer:
Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.6
Explanation:
Answer:
The excretory system is a close partner with both the circulatory and endocrine system. The circulatory system connection is obvious. Blood that circulates through the body passes through one of the two kidneys. Urea, uric acid, and water are removed from the blood and most of the water is put back into the system.
