Options:
A 10-15 times
B 2 times

a. Concentration/pressure gradient.
b. Solubility of the gases (Solubility of CO2 is 20–25 times higher than that of O2, so CO2 can diffuse at a higher rate).
c. Thickness of the membranes (Diffusion membrane at the level of alveoli is having a thickness of less than 1 mm, so it favours the diffusion of gases).

Solubility of the alkaline earth's metal sulphates in water decreases in the sequence

Options:
A Sr > Ca > Mg > Ba
B Ba > Mg > Sr > Ca
C Ca > Sr > Ba > Mg

Solute potential of pure water and its solution are:

Options:
A 0 and 1
B 0 and 0
C 0 and more than 0
D 0 and less than 0

The correct answer is:
0 and less than 0

Solution:
By definition," Water potential is the potential energy of water per unit volume relative to pure water in reference conditions." Thus, water will move from a higher water potential region to the lower potential region through the semipermeable membrane. It can be summarized as total of pressure potential, gravity potential and solute potential. Water potential of a fluid is reduced due to presence of solute as water molecules cluster around solute particles and this is referred to as solute potential. Pure water has the water potential of zero as there is no solute present and the pressure in the system is zero. Since, presence of solute particles reduces the water potential, thus, water potential of a solution will be less water potential of pure water that is less than 0.

Solution of $0.1 \mathrm{~N} \mathrm{NH}_4 \mathrm{OH}$ and $0.1 \mathrm{~N}$ $\mathrm{NH}_4 \mathrm{Cl}$ has $\mathrm{pH~} 9.25$, then find out $\mathrm{pK}_b$ of $\mathrm{NH}_4 \mathrm{OH}$.

Options:
A 9.25
B 4.75
C 3.75
D 8.25

The correct answer is:
4.75

Solution:
Concentration of salt
$\mathrm{NH}_4 \mathrm{Cl}=0.1 \mathrm{~N}$
Concentration of the base $\mathrm{NH}_4 \mathrm{OH}=0.1 \mathrm{~N}$
$\mathrm{pH}$ of solution is 9.25
$\therefore \mathrm{pOH}=14-\mathrm{pH}=14-9.25=4.75$
We know that,
$\mathrm{pOH}=\mathrm{pK}_{\mathrm{b}}+\log \frac{[\text { salt }]}{\text { [base }]}$
(But here concentration of salt $=$ concentrtion of base and $\left[\log _{10}(1)-\right.$ $0]$.
$\therefore \quad \mathrm{pOH}=p \mathrm{~K}_b=4.75$
A Caution
$\begin{aligned}
\mathrm{NH}_4 \mathrm{OH} & \rightleftharpoons \mathrm{NH}_4^{+} \mathrm{Cl}^{-} \\
\mathrm{NH}_4 \mathrm{Cl} & \rightarrow \mathrm{NH}_4^{+}+\mathrm{Cl}^{-}
\end{aligned}$
Due to the common ion effect, the reaction of dissociation of $\mathrm{NH}_4 \mathrm{OH}$ shifts to the left.

Somaclonal variation occurs during

Options:
A Application of colchicine
B Irradiation with gamma rays
C Tissue culture
D Hybridisation

The correct answer is:
Tissue culture

Solution:
Somaclonal variation is defined as genetic variation observed among the progeny of plants regenerated from somatic cells cultured in vitro. Although theoretically, all plants regenerated from somatic cells should be clones, a number of observations have indicated that this is not the case. In addition to the basic genetic implications of this phenomenon, the variation has proven useful in breeding programs of various crop plants.
Thus during tissue culture arising from a clone is not always the case, sometimes a variant can be obtained.

Somatostatin is produced by the

Options:
A adenohypophysis
B neurohypophysis
C pineal gland
D basal part of diencephalon

The correct answer is:
basal part of diencephalon

Solution:
Somatostatin is also known as growth or inhibiting hormone which is produced primarily in the nervous and digestive system by different tissues in the body. It plays a vital role in the regulation of physiological functions and also prevents the production of other hormones. It is secreted by the pancreas to stop the release of insulin and glucagon. Further, it is generated in the hypothalamus, where it prevents the release of growth hormone and thyroid-stimulating hormones from the anterior pituitary.

Topic: Biology, Chemical Coordination and Integration, NEET
Somatostatin is produced by:

Options:
A Adenohypophysis
B Neurohypophysis
C Pineal gland
D Basal part of diencephalon

The correct answer is:
Basal part of diencephalon

Solution:
Hypothalamus is the floor or basal part of diencephalon which is a part of the forebrain. It contains many neurosecretory cells which secrete hormones. These hormones control the formation and secretion of pituitary hormones. The pituitary gland is attached to the hypothalamus via stalk known as infundibulum. The pituitary gland is made up of two lobes : Adenohypophysis and Neurohypophysis and both these parts are dependent on the hypothalamus. Hypothalamus secretes various releasing and inhibiting hormones which bring about the release of hormones of anterior pituitary which is a part of Adenohypophysis. An example is growth hormone from the pituitary is released under the influence of growth hormone-releasing hormone from the hypothalamus. This is known as somatocrinin. The release is inhibited by growth hormone inhibiting hormone i.e. somatostatin.

Some bacteria are able to grow in the streptomycin containing medium due to:

Options:
A natural selection
B induced mutation
C reproductive isolation
D genetic drift

The correct answer is:
natural selection

Solution:
Bacteria are able to grow in a Streptomycin containing medium due to development of resistance to the bacteria by a process called natural selection. Normally bacteria cannot survive in antibiotic containing medium but if it does so it must have acquired resistance against that antibiotic. These are well adapted to grow in streptomycin containing medium and thus are more evolved. So due to natural selection only, the more evolved and better-adapted species is able to survive.

Some bacteria oxidize various inorganic substances such as nitrates, nitrites, and ammonia and use the released energy for their ATP production? These bacteria are called

Options:
A archaebacteria
B photosynthetic autotrophs
C chemosynthetic autotrophs
D heterotrophs

The correct answer is:
chemosynthetic autotrophs

Solution:
Nitrifying bacteria are included as chemosynthetic autotrophs. These bacteria firstly convert ammonia into nitrite and then nitrites are converted into nitrates. In both these processes some energy is liberated which is used for the production of ATP and organic food. Archaebacteia are chemoheterotrophs. Photosynthetic autotrophs use energy of sunlight for production of organic food. Heterotrophs cannot synthesize their own food, they depend on other organisms for food substances.
