What is depolarization of the sarcolemma?
Depolarization of the sarcolemma is the process where there is a change in the electrical charge across the cell membrane of a muscle cell. This change in charge helps to propagate an action potential along the cell membrane, initiating muscle contraction.
Is candle burning physical change?
Physical change means change physically while chemical change means change chemically or change in chemical properties.Like if you would drop a chip of zinc in sulphuric acid it will its color will be changed which is no doubt a physical change.But,also its properties are changed as it will be transformed into zinc sulphate from simple zinc,thus it also undergoes a chemical change. Now,with your question,the candle breaks but the candle remains the candle,so,its not a chemical change but a physical change only.Hope it helps!
Can distillation separate dissolved substances through physical change?
, Yes it can! Hope that helps. I am not sure what else you are asking. Physical changes are changes affecting the form of a chemical substance, but do not change the chemical composition of that substance. Chemical changes occur when a substance combines with another to form a new substance, called synthesis or, alternatively, decomposes into two or more different substances. As in the case of distillation, all you are doing is simply filtering which involves no chemical changes, purely physical. Hope I Helped
What chemical on the muscle membrane destroys the messanger?
Acetylcholinesterase is the enzyme responsible for breaking down the neurotransmitter acetylcholine on the muscle membrane. This breakdown helps terminate the signal transmission at the neuromuscular junction.
Chemical released by blood platelets is?
The chemical released by blood platelets is called serotonin. This neurotransmitter helps regulate various physiological processes such as blood clotting, smooth muscle contraction, and mood.
Which component of physical fitness helps with activities and protects bones and joints?
Muscle strength
Which component of physical fitness helps with daily -life activities and protects bones and joints?
Muscle strength
Is copper and silver a chemical or physical change?
It is a chemical change because it leaves a residue (which is a sign of chemical change) Hope that helps
Why is change important?
chemical change is important because it helps our invirment
Making scrambled eggs involves physical and chemical change. which step invovles a chemical change?
Cooking the eggs,because a solid is formed this is evidence of a chemical change... Hope that helps.
What change do walnuts undergo when they are put through a blender?
Chemical Change. hopes this helps :)
Type of reaction involving a chemical change?
A chemical change is involved in a chemical reaction. This type of reaction involves the formation of new substances with different chemical properties compared to the reactants. This process can involve the breaking and forming of chemical bonds.
What helps start up a chemical change but does not itself take part in the reaction?
Catalyst
What is the significance of the Z line in muscle structure and function?
The Z line is a structural component in muscle fibers that helps to anchor the actin filaments and organize the sarcomeres, which are the basic units of muscle contraction. It plays a crucial role in maintaining the alignment and stability of the muscle fibers during contraction and relaxation, ultimately contributing to the overall function and efficiency of muscle movement.
What is depolarization of the sarcolemma?
Depolarization of the sarcolemma is the process where there is a change in the electrical charge across the cell membrane of a muscle cell. This change in charge helps to propagate an action potential along the cell membrane, initiating muscle contraction.
What is the difference between the ciliary body and the ciliary muscle in the human eye?
The ciliary body is a structure in the eye that produces aqueous humor, while the ciliary muscle is a muscle that helps to change the shape of the lens for focusing.
A substance which helps make a chemical change happen but is not changed itself in the process is called an?
The answer is catalyst
