The major organ is the Kidney
Combustion - the burning of fuels and harmful gases in the atmosphere through factories.
decomposition - when skulls and bones are decomposed to give out carbon dioxide.
diffusion - when the the molecules move from a region of higher concentration to a region of lower concentration.
respiration - when person breathes in oxygen and out carbon dioxide.
photosynthesis - is the process where trees make glucose and oxygen with the help of sunlight and mineral and water from soils.
Answer: Option C.
SAID
Explanation:
The principle the trainer adopted is Specific adaptation imposed demand.
It describe specific adaptation imposed demand because In SAID principle, different sports posses its own unique demand and in order to improve skills base on a particular sports, human body adapts to the imposed demands by practicing the sports unique moves to asserts the sport demand.
Answer: 6) sodium channel activation occurs.
4)a graded depolarization brings an area of excitable membrane to the threshold.
7) sodium ions enter the cell and further depolarization occurs.
1)sodium channels are inactivated.
2) voltage-regulated potassium channels open and potassium moves out of the cell, initiating repolarization.
3) sodium channels regain their normal properties.
5) a temporary hyperpolarization occurs
Explanation:
action potential occurs when the differences in the concentrations of ions on opposite sides of a cellular membrane lead to a voltage of a specific cell location rapidly rises and falls.
The steps involved in this generation are;
First of all the sodium-gated channel activation occurs due to inflow of Na, this is called depolarization. A graded depolarization brings an area of excitable membrane to the threshold. More sodium ions enter the cell and further depolarization occurs. After which the sodium channels are inactivated due to the opening of voltage-regulated potassium channels and potassium moves out of the cell, returning it to it initial resting phase initiating repolarization. sodium channels regain their normal properties. a temporary hyperpolarization occurs which is a transient negative shift after an action potential occurs.
