During Addison’s disease:

BIOLOGY PORTION

MSH and cortical hormones increases MSH and cortical hormones decreases MSH increases, cortical hormones decrease MSH decreases, cortical hormones increase

Excess of adrenaline & nor-adrenaline may lead to: Addison’s disease Cushing disease Low blood glucose High blood pressure

Hormones produced by adrenal cortex are ____ in nature: Steroids Amino acid derivatives Polypeptides Proteins

The adrenal cortex is active in: Shock Stress Infection All A, B, C

Cortisol release is controlled by: STH ACTH TSH FSH

Excess or deficiency of ACTH will affect the functioning of: Hypothalamus Anterior pituitary Adrenal cortex Adrenal medulla

Structures that detect change in environment are called: Stimuli Receptors Control center Effectors

Receptors in ear for detection of sound are examples of Chemoreceptors Thermoreceptors Mechanoreceptors Nociceptor

Stretched receptors present in the carotid and aortic arteries of tetrapods are examples of : Chemoreceptors Photoreceptors Thermoreceptors Mechanoreceptors

Which of the following type of receptors are also called as ‘electromagnetic receptors’? Chemoreceptors Mechanoreceptors Nociceptors Photoreceptors

These receptors are said to be the un-differentiated endings and detect the stimulus of pain: Photoreceptors Thermoreceptors Mechanoreceptors Nociceptors

In skin, the receptors are concerned with at least ___ different senses. 3 4 5 6

All of the following are functions of secretin except: Controls the exocrine secretion of pancreas Stimulates bile production from liver Helps in regulation of duodenal pH Stimulates the production of gastric juice

It is the site of production of secretin: Stomach Duodenum Jejunum Ileum

Gastrin in produced under the influence of _____in the stomach after it is partially digested. Lipid rich food Vitamin rich food Carbohydrate rich food Protein rich food

The sonometer wire is vibrating in the second overtone. We may say that there are:

PHYSICS PORTION

Two nodes and two antinodes One nodes and two antinodes Four nodes and three antinodes Three nodes and three antinodes

A string on a musical instrument is 50 cm long and its fundamental frequency (n) is 270 Hz. If the desired frequency of 1000 Hz is to be produced, the required length of the string is 13.5 cm 2.7 cm 5.4 cm 10.3 cm

When the antinodes are all at their extreme displacements, the energy stored is K.E thermal energy P.E all of these

There is no net transfer of energy by particles of medium in Longitudinal wave Transverse wave Progressive wave Stationary wave

The velocity of waves in a string fixed at both ends is 2 m/s. The string forms standing waves with nodes 5.0 cm apart. The frequency of vibration of the string in Hz is 40 30 20 10

A car blowing a horn of frequency 350 Hz is moving normally towards a wall with a speed of 5 m/s. The beat frequency heard by a person standing between the car and the wall is (speed of sound is air=350 m/s) zero 3.5 Hz 5 Hz 10 Hz

A sound source is moving towards stationary listener with 1/10th of the speed of sound. The ratio of apparent to real frequency is: 9:10 10:9 10:11 11:10

The apparent wavelength of the light from a star moving away from the earth is 0.01% more than its real wavelength. Then the velocity of star is 60 km/sec 15 km/sec 150 km/sec 30 km/sec

It is believed that the universe is expanding and hence the distant stars are receding from us. Light from such a star will show Shift in frequency towards longer wavelengths Shift in frequency towards shorter wavelength No shift in frequency but a decrease in intensity A shift in frequency sometimes towards longer and sometimes towards shorter wavelengths

Work may be defined in terms of pressure-volume as P V F x d H+V H + PV

Incorrect statement about endothermic reaction is Evaporation is an endothermic process Products are more stable than reactants Change in H is positive Reaction mixture become cold

Thermodynamics relates heat with other forms of energy. It does not deal with Gibb’s free energy Activation energy Internal energy Potential energy

First law of thermodynamics relates Heat, work and entropy Internal energy, heat and work Heat, work and external energy Work, internal energy and enthalpy

The enthalpy change for the process C (s) → C (g) Corresponds to enthalpy of Sublimation Combustion Vaporization Fusion

The amount of heat evolved when one mole of CH3COOH reacts with one mole of NaOH is = 57.4 kJ > > 57.4 kJ < 57.4 kJ None

Born Haber cycle is an application of Hess’s law Avogadro’s law 1st law of thermodynamics Law of mass action

Standard heat of formation of Al2O3 cannot be determined directly because Al and O2 do not react Protective layer of Al2O3 form It does not catch fire It reacts with CO2
