#	Question	Ans
1.	A population is defined as the collection of A. Similar organism that are found in the same habitat B. Similar organisms that breed in the same habitat C. Similar organisms that interbreed freely in the same habitat D. Similar organism eating the same food E. Different organisms in the same habitat Show Content Detailed Solution A population is a summation of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding. REF:https://en.wikipedia.org/wiki/Population	C

3.	Which of these animals is NOT metamerically segmented? A. Tapeworm B. Earthworm C. Centipede D. Crayfish E. Shark	E
4.	Some of the major elements required by plants are A. Potassium, nitrogen, phosphorus, sodium, calcium B. Nitrogen, phosphorus, molybdenum, sodium, calcium C. Potassium, phosphorus, molybdenum, sodium, calcium D. Potassium, nitrogen, iron , sodium, calcium E. Potassium, nitrogen, phosphorus, silicon, cadmium	A
5.	In human reproduction, the zygote formed as a result of fertilization gets attached to the wall of the uterus. The process is called A. Sexual reproduction B. Cohesion C. Pregnancy D. Implantation E. Viviparity	D
6.	Kwashiorkor is caused by severe deficiency of A. Water B. Oil C. Drugs D. Proteins E. Sugars Show Content Detailed Solution Kwashiokor is a nutritional disorder most often seen in regions experiencing famine. It is a form of malnutrition caused by a lack of protein in the diet.	D
7.	An hormoiothermic animal kept in a room where the temperature is lower than the body temperature may lose heat by four physical process. Which of the following processes is NOT connected with the body temperature regulation ? A. Radiation B. Sweat C. Evaporation D. Conduction E. Convection	E
8.	Which of these food chains is NOT possible in a forest? A. Diatom → fly → toad → snake B. Fly → toad → snake→ hawk C. Leaves → antelope → man → lion D. Leaves → caterpillar → bird → lion E. Leaves →goat → man→ lion Show Content Detailed Solution Diatoms are an important source of these energy rich molecules that are food for the entire food web, from zooplankton to aquatic insects to fish to whales.	A
