1. Channel receptors- <span>neurotransmitters.</span>
2. Receptor tyrosine kinases-protein expression
3. G protein coupled receptors-<span>detect </span>substances<span> outside the </span>cell
Answer:
Explanation:
Studies indicate that mining is one of the most perilous occupation in the world in terms of injuries and fatalities, and also due to the long term health effects associated with it. Long term effects include respiratory problems such as pneumoconiosis, asbestosis, and silicosis.

C. The lungs
Red blood cells pick up oxygen in the lungs. Blood travels away from the heart and lungs through the arteries. Red blood cells drop off oxygen to the cells through tiny tubes called capillaries. Blood then returns to the heart through the veins and the cycle begins again.
This process is called endocytosis. Endo- means: within, inner, absorbing, or containing
Answer:
1. TEF
2.RMR
3.TEA
Explanation:
The major components that contribute to the body daily expenditure are as follows
1. TEF(Thermal effect of feeding)
2.RMR( Resting metabolic rate )
3.TEA(Thermal effect of activity)
Generally resting metabolic rate consume 60 to 75% of energy for maintenance thwe body temperature.
When body is doing this some physical work then it is called activity related expenditure.
