The hyperbolic equation for the species-area relationship is

Options:
A LogâC=logâS +âZâlogâA
B LogâS=logC+ZâlogâA
C LogâS=logâA+ZâlogâC
D S=CAZ

The correct answer is:
S=CAZ

Solution:
Biodiversity includes all the flora and fauna on Earth. All the varieties of organisms come under biodiversity. German naturalist Alexander von Humboldt made the observation regarding the relationship between species richness and the area of the habitat. As per his observation, species richness increased with increasing area of habitat upto a limit. When plotted in a graph, this relationship forms a rectangular hyperbola having an equation S=CAZ. On a log scale, the relationship is a straight line having the equation
LogS=LogC+ZLogA . S= species richness, A= area of region, C=Y -intercept and Z= regression co-efficient (Slope).

Options:
A u=60 cm, v=15 cm
B u=20 cm, v=10 cm
C u=10 cm, v=20 cm
D u=15 cm, v=60 cm

The correct answer is:
u=15 cm, v=60 cm

Solution:
f=20 cm, m=4

∴m=vu=4⇒v=4u

Using the formula, we have

1f=1v−1u

120=1u−1u⇒120=1−44u

⇒120=−34u⇒4u=−60

The imperfect fungi which are decomposers of litter and help in mineral cycling belong to:

Options:
A Basidiomycetes
B Phycomcetes
C Ascomycetes
D Deuteromycetes

The correct answer is:
Deuteromycetes

Solution:
Deuteromycetes: There is only asexual and vegetative phase known so these are commonly regarded as imperfect fungi. By the establishment of linkages, the perfect stage (or sexual form) discovered in these fungi, they are moved out of Deuteromycetes to ascomycetes and basidiomycetes. The Deuteromycetes reproduces only by asexual spores known as conidia. The mycelium is septate and branched in these fungi. Some of them are saprophytes or parasites while many of them are decomposers of litter (organic matter) and help in mineral cycling.

The incorrect statement among the following is

Options:
A Salvia shows variation in the length of filaments within a flower
B Mustard has polycarpellary syncarpous gynoecium
C In Argemone, ovary is one-chambered but it becomes two chambered due to formation of a false septum
D In cucumber, the gynoecium occupies the highest position while the other floral parts are situated below it

The correct answer is:
In cucumber, the gynoecium occupies the highest position while the other floral parts are situated below it

Solution:
In the hypogynous flower, the gynoecium occupies the highest position while the other parts are situated below it. The ovary in such flowers is said to be superior, e.g., mustard, china rose and brinjal. In epigynous flowers, the margin of the thalamus grows upward enclosing the ovary completely and getting fused with it, the other parts of the flower arise above the ovary. Hence, the ovary is said to be inferior as in flowers of guava and cucumber. There may be a variation in the length of filaments within a flower, as in Salvia and mustard. Flowers are termed syncarpous when carpels are fused, as in mustard and tomato. In parietal placentation, the ovules develop on the inner wall of the ovary or on peripheral part. The ovary is one-chambered but it becomes two-chambered due to the formation of the false septum, e.g., mustard and argemone.

B Enantiomers are superimposable mirror images on each other.

C A racemic mixture shows zero optical rotation.

D SN1 reaction yields 1:1 mixture of both enantiomers.

The correct answer is:
Enantiomers are superimposable mirror images on each other.

Solution:
The product obtained by SN2 reaction of haloalkane having chirality at the reactive site shows inversion of configuration because incoming nucleophile attacks from opposite side of the leaving group.
Enantiomers are non superimposable mirror images of each other. A racemic mixture shows zero optical rotation due to external compensation of optical rotation of the mixture.

The increase in which of these properties doesn't increase the rate of diffusion of a gas across alveoli?

Options:
A Solubility
B Partial pressure gradient
C Thickness of respiratory membrane
D All of these

The correct answer is:
Thickness of respiratory membrane

Solution:
Alveoli are the structural and functional unit of the lungs. They are tiny sacs which helps in the gaseous exchange while breathing by the process of diffusion. Alveoli cells are made of simple epithelial tissue. Alveoli become less efficient because of disease, normal aging, smoking and air pollution. If the gas is more soluble or has higher partial pressure gradient, the transport of gases will be at a faster rate. However, if the thickness of the respiratory membrane increases the diffusion of gases across it will decrease.

Options:
A green house effect.
B eutrophication.

The correct answer is:
eutrophication.

Solution:
Natural aging and nutrient enrichment of a water body is termed as eutrophication. Due to the human activities of adding sewage and industrial waste, water bodies like lake have been heavily eutrophised. Contaminants like nitrates and phosphates overstimulate algal growth as a consequence deplete the oxygen level in water body. Also, other pollutants poison the population of aquatic life leading to their death and increasing the rate of decomposition by bacteria which further depletes the oxygen level.
