Particles in the PM25 size range are able to travel deeply into the respiratory tract, reaching the lungs. Exposure to fine particles can cause short-term health effects such as eye, nose, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath. Exposure to fine particles can also affect lung function and worsen medical conditions such as asthma and heart disease.

Iron is an essential part of the proteins that transport oxygen in the body. Hemoglobin, the oxygen- canying protein in red blood cells, accounts for about two-thirds of the body's iron supply. Smaller amounts are found in myoglobin, the protein that supplies oxygen to muscles, and in enzymes needed for various biochemical reactions.
[24] An adult human normally has -
A.
6 molar teeth
B.
8 molar teeth
C.
10 molar teeth
D.
12 molar teeth
Ans:
12 molar teeth
Explanation :
Molars are the posterior most and most complicated kind of tooth in most mammals. Adult humans have twelve molars, in four groups of three at the back of the mouth. The third, rearmost molar in each group is called a wisdom tooth.
[25] Chicken pox is caused by -
A.
Protozoa
B.
Bacteria
C.
Virus
D.
Fungus
Ans:
Virus
Explanation :
Chickenpox is a highly contagious disease caused by primary infection with varicella zoster virus (VZV), It is an airborne disease spread easily through coughing or sneezing of ill individuals or through direct contact with secretions from the rash.
Explanation :
The Sarus Crane is the state bird of Uttar Pradesh. These birds have always been known to inhabit the state, and even historic epics originating from the state have made references to the species (Leslie 1998).
[14] The animal who can consume more salt among the following is -
A.
Sheep
B.
Camel
C.
Donkey
D.
Dog
Ans:
Camel
Explanation :
Camels require six to eight times the salt intake of other animals. This helps the camel's body to store water in its cells. At an average, camels need a ration of 45-60 grams of salt every day.
[15] How many chambers does a mammalian heart have?
A.
4
B.
1
C.
2
D.
3
Ans:
4
Explanation :
Most mammalian hearts are structured similarly to the human heart. There are 4 chambers found within the mammalian heart: the left atrium, right atrium, left ventricle, and right ventricle.
[16] The release of which of the following into ponds and wells helps in controlling mosquitoes?
A.
Snaii
B.
Crab
C.
Dogfish
D.
Gambusia fish
Ans:
Gambusia fish
Explanation :
The Gambusia fish, also known as mosquito fish, feeds on the larvae of mosquitoes. So it helps in controlling their population. Mosquito fish were introduced directly into ecosystems in many parts of the world as a bio-control to lower mosquito populations which in turn negatively affected many other species in each distinct bioregion.
[17] The ambient air is stable when the ambient lapse rate is -
A.
Neutrally stable
B.
Hyper-adiabatic
C.
Sub-adiabatic
D.
Super-adiabatic
Ans:
Sub-adiabatic
Explanation :
[18] In dicots the pollen-grains possess :
A.
two germ pores
B.
three germ pores
C.
four germ pores
D.
one germ pore
Ans:
three germ pores
Explanation :
Pollen grains of monocots have one opening, while pollen grains of dicots have three openings. Pollengrains can be monocolpate (having one germ pore called germinal furrow e.g., monocots), bicolpate (2 germ pores) and tricolpate (3 germ pores e.g., dicots).
[19] Acceptable "Noise Pollution Level" in India range between:
A.
16 - 35 db
B.
40 - 45 db
C.
70 - 100 db
D.
10 - 15 db
Ans:
40 - 45 db
Explanation :
According to the noise pollution rules, the permissible noise level during the day is 50dB in silence zones, 55dB in residential areas, 65 dB in commercial areas and 75 dB in industrial areas. The night time permissible levels for silence zones, residential areas, commercial areas and industrial areas are respectively 40 dB, 45 dB, 55 dB and 70 dB.
[20] An example of protein which acts as a hormone is :
A.
nypsin
B.
Oxytocin
C.
Keratin
D.
Casein
Ans:
Oxytocin
Explanation :
Hormonal Proteins are messenger proteins which help to coordinate certain bodily activities. Examples include Insulin, Oxytocin, and Somatotropin. Oxytocin stimulates contractions in females during childbirth.
[21] The primary producer in an ecosystem are;
A.
Women
B.
Men
C.
Plants
D.
Bacteria
Ans:
Plants
Explanation :
Primary producers are the organisms in an ecosystem that produce biomass from inorganic compounds (au totrophs). In almost all cases these are photosyni helically active organisms (plants, cyanobacteria and a number of other unicellular organisms.
[22] White Revolution' is related to -
A.
Wheat production
B.
Milk production
C.
Flood control
D.
Fish production
Ans:
Milk production
Explanation :
White Revolution is related to enhanced milk production. Verghese Kurien, father of the "White Revolution" and founder of the cooperative dairy movement in India passed away on September 9, 2012
