Respiratory and circulatory systems work hand in hand to expel wastes. respiratory system removes CO2 and the circulatory uses the blood as a medium to move excess salts and water from source to sink.
The correct answer is: D) excited
A molecule is in an excited state when its energy level is higher than the ground state. That molecule stays in excited state for short time and then returns to a state with lower energy. This return to a lower energy level is described as decay and is the inverse process of excitation.
The transition from ground to excited state of an atom is possible if electrons gain energy that is higher than the difference in energies between the two energy orbits.
Sugar and it’s because they are very similar
<span>The right option is <span>B) Combination of all the wavelengths of visible light
</span><span>White light is formed when there is mixture of all the colors of the visible light spectrum (ROYGBIV). White light is perceived when all the wavelengths of the visible light spectrum strike the eye at the same time. The sensation of white is not the result of a single color of light.

In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy.
This relates to the speed at which an object should travel to "break" free of any gravitational pull.
Venus: 10.46 km/s
Mars: 5.027 km/s
