Russell’s Vipers are highly venomous terrestrial snakes found in India which are known for their dark brown spots and lustrous skin. Russell’s Vipers are protected under the schedule II of Wildlife Protection Act. Russell’s Vipers, although belong to the class reptilila of vertebrates, give birth to young ones instead of laying eggs. Primarily nocturnal in nature, the snake is often responsible for the majority of snakebite incidents.
[2] The colour of the eye depends upon the pigment present in -
A.
cornea
B.
iris
C.
rods
D.
cones
Ans:
iris
Explanation :
Eye colour is a polygenic phenotypic character determined by 2 distinct factors: the pigmentation of the eye iris and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma.
[3] DNA finger printing is used to identify the -

120 - 140 mg%
C.
140 - 180 mg%
D.
180 - 200 mg%
Ans:
180 - 200 mg%
Explanation :
Cholesterol is defined as a waxy alcohol, fat-like substance that occurs naturally in all areas of the human body. 100-200 mg/dL is considered as normal for the human beings. However it must be noted that total cholesterol counts below 180 mg/dl increase the risk for hemorrhagic stroke; below 180 cholesterol levels are inversely associated with risk. Total cholesterol counts above 200 mg/dl may be normal and healthy for some people, as the ratio of LDL to HDL cholesterol is considered a more important factor in prediction of disease risk.

D.
Retinene
Ans:
Retinene
Explanation :
Retinene–1 is better known as retinaldehyde or simply retinal and is fundamental in the transduction of light into visual signals in the photoreceptor level of the retina (known as the visual cycle). Retinene–2 is more formally known as dehydroretinaldehyde. The energy of impinging photons will convert retinaldehyde from an 11-cis isomer into an all-trans form. In the retina, this conversion induces a conformational change in the surrounding photopsin protein pigment, leading to signaling through the G protein transducin. Retinaldehyde also forms a part of bacteriorhodopsin, a light-induced proton pump found in some archaea.

[15] The ability of the eye to see in the dark, is due to the production of a purple pigment known as -
A.
Carotene
B.
Rhodopsin
C.
Iodopsin
D.
Retinene
Ans:
Retinene
Explanation :
Retinene–1 is better known as retinaldehyde or simply retinal and is fundamental in the transduction of light into visual signals in the photoreceptor level of the retina (known as the visual cycle). Retinene–2 is more formally known as dehydroretinaldehyde. The energy of impinging photons will convert retinaldehyde from an 11-cis isomer into an all-trans form. In the retina, this conversion induces a conformational change in the surrounding photopsin protein pigment, leading to signaling through the G protein transducin. Retinaldehyde also forms a part of bacteriorhodopsin, a light-induced proton pump found in some archaea.

The sound is produced by vibrations of some or all of the membrana tympani forms (the walls of the syrinx) and the pessulus caused by air flowing through the syrinx.
[15] The ability of the eye to see in the dark, is due to the production of a purple pigment known as -
A.
Carotene
B.
Rhodopsin
C.
Iodopsin
D.
Retinene
Ans:
Retinene
Explanation :
Retinene–1 is better known as retinaldehyde or simply retinal and is fundamental in the transduction of light into visual signals in the photoreceptor level of the retina (known as the visual cycle). Retinene–2 is more formally known as dehydroretinaldehyde. The energy of impinging photons will convert retinaldehyde from an 11-cis isomer into an all-trans form. In the retina, this conversion induces a conformational change in the surrounding photopsin protein pigment, leading to signaling through the G protein transducin. Retinaldehyde also forms a part of bacteriorhodopsin, a light-induced proton pump found in some archaea.

Dermatitis
C.
Beri - Beri
D.
Phynoderma
Ans:
Beri - Beri
Explanation :
Beriberi is a nervous system ailment caused by a thiamine (vitamin B 1) deficiency in the diet. Thiamine is involved in the breakdown of molecules such as glucose and is also found on the membranes of neurons. Symptoms of beriberi include severe lcthari and fatigue, together with complications affecting the cardiovascular, nervous, muscular, and gastrointestinal systems.

Ans:
Whales
Explanation :
Animals, such as mammals and birds, that maintain a constant body temperature regardless of the temperature of the surroundings are called warm blooded. It describes animal species which have a relatively higher blood temperature, and maintain thermal homeostasis primarily through internal metabolic processes. Examples of warm blooded animals include: mammals, cats, dogs, humans, giraffes, elephants, bears, beavers, chickens, monkeys, whales, deer, cows, wolf, birds, etc. Cold Blooded animals use external means to control their body temperature. These ectothermic methods include basking in the sun, hiding in the shade, changes in metabolic rate. Some animals’ body temperature even change with there environment. Animals that fall into this category are: fish, insects, spiders, frogs, snakes, alligators, toads, turtles, sharks, etc.
