The solution to this is to use the n = c / v equation
Where:
c is the speed of light: 3x10^8; and
The idea that v = m/s
So plug in the m/s for v in the n = c v equation and you will
get:
1.5 = (3 x 10 ^ 8)/ ((4.5m)/s))
Therefore, the time should be 2.25 x 10 ^ -10 seconds.
A mitotic inhibitor chemotherapy drug would cause the DNA to break during the early stages of cell division. Mitotic inhibitors are drugs derived from natural plant sources, and work by inhibiting cell division or mitosis, where a single cell divides into two genetically identical daughter cells. They may bind to tubulin and inhibit its polemerization into microtubules.
You must use intense Heat and pressure to change a sedimentary rock into a metamorphic
Ecosystem an area where plants, animals, and other organisms, co-ordinate for their living. According to energy pyramid, ecosystem can support fewer foxes than grasshoppers.
<h3>What is energy pyramid?</h3>
Energy pyramid is the flow of energy from one tropic level to another which is always erect.
After each level, 90% energy is lost in environment as heat. There is loss of energy at each tropic level.
As foxes comes after grasses in energy pyramid, so the ecosystem can support fewer foxes than grasshoppers.
Thus, the correct option is A.

Answer:
Reflex action is the sudden uncontrolled reaction towards a certain stimuli eg response to hot iron
Reflex arc is the path taken by reflex action to a certain stimuli
Diagram depends to
Receptor(eg skin), receptor nerve(sensory neurone),centre reflex arc(spinal cord most of reflex action) they met relay neurone, motor neurone and ends at reflexor (eg muscle)
