The correct answer is B. Electrons flow because of electrical attraction and repulsion.
Traditional is the old way of doing stuff, Command is a system ruled by one person, Market is having buyers and sellers make economic decisions
None of those choices is a device commonly used to detect
the presence of a static electric charge. One of them is a
process or technique, and is not even a 'device'.
A couple of them might be jerry-rigged to detect charge, but
that is not their intended purpose or design, and it would take
some ingenuity. They're certainly not "commonly used" in that
application.
-- Compass . . . a device that detects the presence of a magnetic
field and displays its direction.
-- Voltmeter . . . a device that displays the presence and measures
the magnitude and direction of electric potential
difference between two points.
-- Electrophoresis . . . a method of separating macro molecules
according to their size.
-- Galvanometer . . . a device used to detect the presence and
measure the magnitude and direction of
small electric currents.
Explanation :
(1) Involuntary muscles are the muscles that are not controlled by our will.
(2) Tendons are the connective tissues that join the muscle to bones. Tendons are tissues that have fibers.
(3) Cardiac muscle is also involuntary muscles. For example heart muscle. It shows contraction and relaxation throughout life.
(4) Voluntary muscle is the muscles that are not controlled by our will.
(5) Biceps are the arm muscles.
Hence, this the required explanation as per options.
Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water.
