Solutions

S1.Ans. (a)
Sol. Medulla is the region in hind brain which is responsible for controlling involuntary actions such as blood pressure, vomiting, sneezing, salivation etc.

S2.Ans. (d)
Sol. Hormones are poured directly into the blood. Blood helps hormones to reach at their target place.

S3.Ans. (b)
Sol. Insulin regulates the blood sugar level by converting glucose into glycogen. It is secreted by pancreas and its deficiency leads to diabetes.

S4.Ans. (a)
Sol. Water gas is a synthetic gas, having CO and H2. The gas is produced by passing steam over a red hot hydrocarbon fuel as coke.

S5.Ans. (b)
Sol. Combination of one volume of nitrogen with three volumes of hydrogen produces two volumes of ammonia.

S6.Ans. (d)
Sol. Emulsion is known as a colloidal solution of two liquids.

S7.Ans. (b)
Sol. Hexane do not give sooty flame as it is alkane and saturated compound where as Benzene, Naphthalene and Anthracene are aromatic and unsaturated so they give sooty flame.

S8.Ans. (c)
Sol. Malaria is a communicable (protozoan) disease caused by Plasmodium vivax while others are congenital (genetic) disorders. Plasmodium enters the human body as sporozoites (infections form) through the bite of infected female Anopheles mosquito.

S9.Ans. (c)
Sol. Arthropods have body cavities (coelomates), with main internal cavity called haemocoel which accomodates their internal organs and through which blood circulates. They have open circulatory system.

S10.Ans. (b)
Sol. Typhoid is a bacterial disease caused by Salmonella typhi. Streptococcus sp. are responsible for meningitis, pneumonia, endocarditis etc. Giardia is an anaerobic flagellate protozoans causes giardiasis. Myco-bacterium sp. causes tuberculosis and leprosy.
