[1] The animal which uses sounds as its ‘eyes’ is -
A.
Dog
B.
Cat
C.
Snake
D.
Bat
Ans:
Bat
Explanation :
Bat echolocation is a perceptual system where ultrasonic sounds are emitted specifically to produce echoes. By comparing the outgoing pulse with the returning echoes, the brain and auditory nervous system can produce detailed images of the bats surroundings. This allows bats to detect, localize and even classify their prey in complete darkness. At 130 decibels in intensity, bat calls are some of the most intense, airborne animal sounds.

[3] At very high altitude, the Red Blood Corpuscles in the human body will :
A.
increase in size
B.
decrease in size
C.
increase in number
D.
decrease in number
Ans:
increase in size
Explanation :
Red Blood cells contain haemoglobin which is what the oxygen binds with to form oxyhaemoglobin which is then transported to the different cells around the body. Oxygen bonds with the haemoglobin when it is at high partial pressure and then is released when there is a lower partial pressure of oxygen. At high altitude there is lower atmospheric pressure of oxygen. This means that the current number of red blood cells in the body cannot meet the cells demands for oxygen.

[13] Which of the following hormone is released in excess quantity during excitement?
A.
Cortisone
B.
Serotonin
C.
Adrenaline
D.
Oestrogen
Ans:
Oestrogen
Explanation :
Estrogens (AmE), or oestrogen (BE), are a group of compounds named for their importance in the estrous cycle of humans and other animals. These hormones are released in excess during excitation. They are the primary female sex hormones. Natural estrogens are steroid hormones, while some synthetic ones are non-steroidal. Estrogens, in females, are produced primarily by the ovaries, and during pregnancy, the placenta. Follicle-stimulating hormone (FSH) stimulates the ovarian production of estrogens by the granulosa cells of the ovarian follicles and corpora lutea. Some estrogens are also produced in smaller amounts by other tissues such as the liver, adrenal glands, and the breasts.

[21] Which of the following hormones is released in excess quantity during excitement’?
A.
Cortisone
B.
Serotonin
C.
Adrenaline
D.
Oestrogen
Ans:
Oestrogen
Explanation :
Estrogens (AmE), or oestrogen (BE), are a group of compounds named for their importance in the estrous cycle of humans and other animals. These hormones are released in excess during excitation. They are the primary female sex hormones. Natural estrogens are steroid hormones, while some synthetic ones are non-steroidal. Estrogens, in females, are produced primarily by the ovaries, and during pregnancy, the placenta. Follicle-stimulating hormone (FSH) stimulates the ovarian production of estrogens by the granulosa cells of the ovarian follicles and corpora lutea. Some estrogens are also produced in smaller amounts by other tissues such as the liver, adrenal glands, and the breasts.
