Solution:
Structure	Location/Characteristics

Organ of Corti	Resting on the basilar membrane is the organ of Corti (organ of hearing). The organ of Corti has about 16,000 hair cells, which are arranged into two groups. The inner group consists of only one row of cells and the outer group consists of multiple rows of cells.

Cochlea	Functionally the inner ear is differentiated into vestibular apparatus for the sense of equilibrium and cochlea for the sense of hearing.

Eustachian tube	The middle ear is connected to the nasopharynx through the Eustachian tube. This helps in equalizing the air pressure on both sides of the eardrum.

Stapes	The base of the stapes lies on the membrane of the oval window (an opening of the cochlea). The middle ear ossicles transmit the sound waves from the tympanum to the oval window of the cochlea.

Column-I	Column-II

(a)	Pituitary gland	(i)	Grave’s disease

(b)	Thyroid gland	(ii)	Diabetes mellitus

C (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
D (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)

The correct answer is:
(a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)

Solution:
Grave's disease: Due to cancer of the thyroid gland, due to development of nodules of the thyroid glands, or due to autoimmunity, the rate of synthesis and secretion of the thyroid hormones is increased to abnormally high levels leading to a condition called hyperthyroidism which adversely affects the body physiology. It leads to Grave’s disease or exophthalmic goiter. It causes weight loss, increased metabolism, rapid reflexes, nervousness, etc.

Diabetes mellitus: It is caused due to insulin deficiency or hypofunctioning of beta cells of Islets of Langerhans of the pancreas. Urine is sweet to taste due to the presence of sugar. Due to the presence of sugar, there is failure in normal osmotic reabsorption of water by kidney tubules.

Diabetes insipidus: It is caused due to deficiency of ADH or hypofunctioning of the pituitary. Sugar is generally absent in urine. Absence of ADH decreases the permeability of collecting tubule.

Addison's disease: It is caused due to hypofunctioning of adrenal or suprarenal glands or due to deficiency of cortisol and sometimes aldosterone too.

Column-I	Column-II

(a)	Pneumotaxic centre	(i)	Alveoli

(b)	O2 Dissociation curve	(ii)	Pons region of brain

(c)	Carbonic anhydrase	(iii)	Haemoglobin

D (a)-(iv), (b)-(i), (c)-(iii), (d)-(ii)

The correct answer is:
(a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)

Solution:
The centres in pons influence the rhythmicity centre of the medulla. Pons has pneumotaxic centre and apneustic centre. The pneumotaxic centre inhibits the inspiratory neurons and facilitates expiration as a result the breathing rate becomes increased.

Alveoli is the primary site of the lungs where the exchange of gases takes place between lungs and blood capillaries.

RBC has the presence of a carbonic anhydrase enzyme that helps in bidirectional reaction, i.e. formation and dissociation of carbonic acid.

The oxygen dissociation curve explains the saturation of O2 with haemoglobin.

The correct answer is:

Solution:
Binary fission is a type of asexual mode of reproduction where the cell divides in two to form two new identical daughter cells. It is the most common form of reproduction observed in bacterial groups and also in some unicellular eukaryotes like Amoeba and Paramecium (type of protozoans).
Gemmules are internal buds which are asexually reproduced mass of cells found in Sponges. These are capable of developing into a new organism.
In certain organisms, small buds are produced attached to the parent organism which grow and eventually separate to develop into new organism. This process is called budding and it is a type of asexual reproduction. Hydra follows budding pattern of asexual reproduction.
Asexual spore which are motile and show locomotion using flagella is called zoospore. Many algal groups, bacteria show zoospore formation.
Penicillium a type of fungi reproduces asexually by producing non-motile spore called as conidium.
