Taking the example of heart beat, justify the antagonistic (opposite) action of the sympathetic and parasympathetic nerves.

Fill in the blanks with suitable words given below. Fluctuation s of hormone (i)_____________ levels results in sensation of hunger and motivation of consuming food. When you feel your stomach is full and there is no need of food any more. Another hormone (ii)_____________ that gets secreted suppresses hunger. When we take food into the mouth it has to be chewed thoroughly. For this purpose the (iii)_____________ muscles help in chewing actions, while the (iv)_____________ muscles of the jaw moves the jaw up,down ,forward and backward during food mastication. The (v)_____________ nerve controls the muscles of the jaw. . Under the action of (vi)_____________ nervous system Saliva is released by the salivary glands moistens the food to make chewing and swallowing easier. The salivary (vii)_____________ in the saliva breaks down the starch into sugars. As a result of chewing the food is transported into the oesophagus by the action of swallowing which is coordinated by the swallowing centre in the (viii)_____________ and the (ix)_____________. The tongue which is gustatory recognizes the taste and (x)_____________ nerve plays an important role in sensation of taste. Choose the right ones. 1) leptin, grehlin gastrin secretin. 2) ghrelin leptin secretin gastrin. 3) deep muscles ,surface muscles ,circular muscles, striated muscles. 4) surface muscles, deep muscles, neck muscles, long muscle. 5) fifth cranial nerve ,second cranial nerve,fifth facial nerve, spinal nerve. 6) central nervous system, peripheral nervous system autonomous nervous system. 7) lipase, sucrase, galactase,amylase. 8) medulla oblongata, cerebrum , 8th spinal nerve,cranial nerve.7th cranial nerve. 9) Pons varoli, brain stem ,medulla oblongata, mid brain. 10) 6^(th) cranial nerve, 5^(th) cranial nerve, 10^(th) cranial nerve, optic nerve.

I am the Cranial Nerve controls the heart beat and functioning Pancreas. Who am i?

Norepinephrine (i)Is released by sympathetic fibres (ii)Is released by parasympathetic fibres (iii)Increases the heart rate (iv)Decreases blood pressure Which of the above statements are correct?

We know that, If 7=2^x then x=log_(2)7. Then what is the value of 2^(log_(2)7) ? Justify your answer. Generalise the above by taking some more examples for a^(log_(a)N).

Structure and function are correlatable in living organisms. Can you justify this by taking plasma membrane as an example ?
