through which it travels.
C. Light travels as both a wave and a particle.
D. Light can not travel through a vacuum. - correct
answers✅✅C. Light travels as both a wave and a particle.
Light is a curiosity in that it acts as both a wave and a particle. It
only changes direction via reflection (bouncing off of something)
or refraction (passing from one medium to another). In a vacuum,
the speed of light is constant, but when passing through a
medium that has an index of refraction different from a vacuum,
light's speed slows.

Those with an AB- blood type should not receive blood from those

antigens, the person with AB- blood lacks a special protein, or
"Rhesus" Factor (Rh), circulating in their blood. If they are given
blood that has the Rh factor present, their body will make

not be correct because it is not an artery, it is a vein and the
question asks for an artery.
