That's not a question, but I guess I'll just vomit some information at you and hope I hit a target.
First of all, not true. Unless you're talking multiple choice kind of thing.
Room temperature is 20 degrees C / 68 degrees F / 293 degrees K
At this temperature, most elements are solids, but
Mercury and bromine are liquids
Hydrogen, helium, nitrogen, oxygen, flourine, neon, chlorine, argon, krypton, xenon, and radon are all gases.
Answer:
The correct answer will be option-B.
Explanation:
The patellar tendon reflex is the kicking movement of the lower leg in response to the tap on patellar cap used to test the L2, L3, and L4 segments of the spinal cord in the body.
The spinal cord interacts with muscles through muscle sensors called muscle spindle which signals after the stretching of the muscle. The signals are sent to the spinal cord through afferent neurons or sensory neurons which starts the reflex action to prevent overstretching of the muscle.
Thus, Option-B is the correct answer.
A and B i believe, hope it helped.
