Mechanoreceptor
Explanation :
Baroreceptors are sensors located in the blood vessels of all vertebrate animals that sense the blood pressure and relay the information to the brain, so that a proper blood pressure can be maintained. They are a type of mechanoreceptor sensory neuron that is excited by stretch of the blood vessel. Mechanoreceptors are the sensory receptors that respond to any type of primary stimuli of pressure.
[2] The concept of ‘survival of the fittest’ was first advocated by -
A.
Oparin
B.
Darwin
C.
Spencer
D.
Haeckel
Ans:
Darwin
Explanation :
Survival of the fittest is a phrase originating in evolutionary theory, as an alternative description of natural selection. The phrase is today commonly used in contexts that are incompatible with the original meaning as intended by its first two proponents: British polymath philosopher Herbert Spencer (who coined the term) and Charles Darwin. Herbert Spencer first used the phrase - after reading Charles Darwin's On the Origin of Species - in his Principles of Biology (1864), in which he drew parallels between his own economic theories and Darwin's biological ones.
[3] Deficiency of vitamin D in children causes -
A.
beriberi
B.
pellagra
C.
rickets
D.
scurvy
Ans:
rickets
Explanation :
Rickets is a softening of bones in children due to deficiency or impaired metabolism of vitamin D, phosphorus or calcium, potentially leading to fractures and deformity. Rickets is among the most frequent childhood diseases in many developing Countries. The predominant cause is a vitamin D deficiency, but lack of adequate calcium in the diet may also lead to rickets (cases of severe diarrhea and vomiting may be the cause of the deficiency). Although it can occur in adults, the majority of cases occur in children suffering from severe malnutrition, usually resulting from famine or starvation during the early stages of childhood.

[9] 'Barr body' is found in -
A.
Sperm
B.
Sertoli cells
C.
Female somatic cells
D.
Male somatic cells
Ans:
Female somatic cells
Explanation :
The Barr body, also sometimes called the sex chromatin, is the inactive X chromosome in female somatic cells. Human females have two X chromosomes, while males have one X and one Y. In all of the female somatic cells, which don’t take part in sexual reproduction, one of the X chromosomes is active, and the other is inactivated in a process called lyonization, becoming the Barr body. The reason for shutting off one X chromosome is so that only the necessary amount of genetic information is expressed, rather than double or even more. This is why X-inactivation doesn’t only occur in humans, but in all organisms whose gender is determined by the presence or absence of a Y or W chromosome in the cell. In short, the amount of X chromosome genes expressed has to be equal in both males and females.

A.
Vitamin A
B.
Vitamin D
C.
Vitamin B
D.
Vitamin C
Ans:
Vitamin D
Explanation :
Vitamin D is essential in helping the body absorb and use calcium; in fact, the body cannot absorb calcium at all without some vitamin D. Vitamin D helps our intestines absorb calcium from the food we eat and helps build stronger bones, partly by increasing the absorption of calcium.
[25] Which of the following vitamins contain nitrogen?
A.
Vitamin A
B.
Vitamin B
C.
Vitamin C
D.
Vitamin D
Ans:
Vitamin B
Explanation :

[7] Cell becomes turgid because of -
A.
Plasmolysis
B.
Exosmosis
C.
Endosmosis
D.
Diffusion
Ans:
Endosmosis
Explanation :
When the plant cell is placed in a hypotonic solution, it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is said to have become "turgid" i.e. swollen and hard. So it is because of endosmosis that cell becomes turgid.
[8] The process of imbibitions involves -
A.
Diffusion
B.
Capillary action
C.
Absorption
D.
Both (1) and (2)
Ans:
Absorption
Explanation :
The uptake or absorption of water by the solid substance without forming a solution is called imbibition. The substances absorbing water are called imbibants which do not dissolve in water. It is the initial step in the germination of the seeds.
[9] 'Barr body' is found in -
A.
Sperm
B.
Sertoli cells
C.
Female somatic cells
D.
Male somatic cells
Ans:
Female somatic cells
Explanation :
The Barr body, also sometimes called the sex chromatin, is the inactive X chromosome in female somatic cells. Human females have two X chromosomes, while males have one X and one Y. In all of the female somatic cells, which don’t take part in sexual reproduction, one of the X chromosomes is active, and the other is inactivated in a process called lyonization, becoming the Barr body. The reason for shutting off one X chromosome is so that only the necessary amount of genetic information is expressed, rather than double or even more. This is why X-inactivation doesn’t only occur in humans, but in all organisms whose gender is determined by the presence or absence of a Y or W chromosome in the cell. In short, the amount of X chromosome genes expressed has to be equal in both males and females.

[14] Conversion of starch to sugar is essential for -
A.
Stomatal opening
B.
Stomatal closing
C.
Stomatal formation
D.
Stomatal growth
