DNA is deoxyribonucleic acid while RNA is ribonucleic acid !
DNA has base pair of adenine guanine thymine and cytosine.....while RNA has adenine guanine cytosine and uracil !
DNA is always double helix while RNA is mainly single helix !
DNA contains genetic info for 99℅ of organism while RNA is being catalytic and unstable than DNA is only present as genetic information holder in 1℅ !
DNA does not involve in protein synthesis directly but RNA has to !
for more difference, comment !
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)
Air pressure is what you measure with a tire gauge. Atmospheric pressure is what you measure with a mercury barometer. Let me be more specific. Pressure is the amount of force per unit area that a gas exerts on a surface.
Answer:
Yes, the statement is true.
Explanation:
Different substances requires different amount of heat because every materials has its own specific heat capacity. Heat capacity is the amount of heat required to increase its temperature by 1 degree. Different substances have different types of bonds due to which they required different amount of heat energy for its breaking.
For example, heat requirement of water is different from glucose because they are made of different substances.
