P is a small, round, reddish structure located on the dorsal side of forebrain. It contains a stalk-and releases a hormone Q which controls diurnal rhythm of the body. P and Q are

Which of the following statements are correct ? 1. The hormone responsible fore maintaining the diurnal rhythm of the body is secreted by a gland situated on the dorsal side of thee forebrain . 2. Exophthalmic goitre is characterized by protrusion of eyeballs , weight loss , enlargement of the thyroid gland and decreases basal metabolic rate . 3. Addison's disease occurs due ti decreased production of hormones from the outer part of the adrenal gland. 4. Hyper secretion of parathormone cause an increase in the deposition of calcium in bones .

A compound of elements P and Q has a crystalline structure based on cubic unit cells. The corners and face centres of the unit cell are occupied by P atoms, while its body centre and edge centres are occupied by Q atoms. Predict the probable formula of the compound.

When 100 drops of a liquid P is added into a liquid Q the volume of the liquid in the container which is initially filled with liquid Q doubled. Determined density of the mixture if density of the liquids P and Q are 1.5 g cm ^(-3) and 1.3 g cm^(-3), respectively

Oil is filled in a cylindrical container up to height 4m. A small hole of area 'p' is punched in the wall of the container at a height 1.52m from the bottom. The cross sectional area of the container is Q. If p/q = 0.1 then v is (where vis the velocity of oil coming out of the hole)

A cylindrical structure P in our body begins in continuation with medulla and extends downwards. It is enclosed in a bony cage Q and surrounded by membranes R. As many as x pairs of nerve arise from the structure P. The structure P is involved in the reflex actions of our body and conduction of nerve impulse to and from another organs S of our body with which it forms CNS. (a) Name the structure P. (b) Name (i) bony cage Q, and (ii) membranes R. (c) How much is x? (d) Name the organ S. (e) What are the reflexes involving structure P only known as?

There are two similar glands P which are located on the top of two similar organs Q in the human body. The glands P are often called glands of emergency and they secrete a hormone R into the blood stream. The hormone R is secreted in large amounts when a person is frightened. It brings about temporary changes in the body which allow a lot of substance S from the liver to go into blood so as to provide a lot of energy in a very short time. This helps the person concerned to flight back or run away from the frightening situation. what are P,Q,R and S?

A rigid body is rotating about fix axis. P and Q are its particles. Which of the following physical quantity is same for P and Q?
