S1. Ans.(d)
Sol.Other than nucleus mitochondria contains DNA and are able to synthesis their own proteins they are regarded as semiautonomous organelles.
S2. Ans.(b)
Sol.Refers to the structure formed by double-stranded molecules of nuclei acid such as DNA. A thread like body in the cell nucleus that carries the genes in a linear order. They carry hereditary information from one generation to the next in the form of genes. It is made up of protein and DNA
S3. Ans.(b)
S4. Ans.(a)
S5. Ans.(c)
Sol. Wood is a porous material and will absorb moisture from the air. Moisture is attracted to the walls of the tubes that make up the wood. Wood will only decay if it is in contact with the ground or wetted by an external source of moisture, such as rain seepage, plumbing leaks, or condensation. Dry wood will never decay. Also, the drier the wood, the less likely it is to be attacked by most types of wood-inhabiting insects. Wood-inhabiting fungi are small plants that lack chlorophyll and use wood as their food source. 
S6. Ans.(c)
Sol. Ampicillin is the large spectrum anti-biotic most commonly used. Ampicillin is a beta-lactam antibiotic that is part of the amino-penicillin family and is roughly equivalent to its successor, amoxicillin in terms of spectrum and level of activity. It can sometimes result in reactions that range in severity from a rash (in the case of patients that may unwittingly have mononucleosis) to potentially lethal allergic reactions such as anaphylaxis. However, as with other penicillin drugs, it is relatively non-toxic and adverse effects of a serious nature are encountered only rarely.
S7. Ans.(a)
Sol.Our bones and teeth are generally made up of Tricalcium Phosphate. Tricalcium phosphate is a calcium salt of phosphoric acid with the chemical formula Ca3(PO4)2. It is also known as tribasic calcium phosphate and bone phosphate of lime, BPL. Calcium phosphate is one of the main combustion products of bone. The skeletons and teeth of vertebrate animals are composed of calcium phosphate
S8. Ans.(a)
Sol.Angora wool refers to the downy coat produced by the Angora rabbit. Angora is known for its softness, thin fibres, and what knitters refer to as a halo (fluffiness). It is also known for its silky texture. It is much warmer and lighter than wool due to the hollow core, Angora rabbits produce coats in a variety of colours, from white through tan, gray, and brown to black
S9. Ans.(a)
Sol.For women, heart disease symptoms may be subtle – but when a heart attack strikes, women are more likely to die than men. Women are also at twice the risk of death following open heart surgery, compared to men. Researchers say when men have heart disease it affects the larger blood vessels, but in women, the small blood vessels become diseased
S10. Ans.(a)
Sol.In vertebrate anatomy the pituitary gland is an endocrine gland about the size of a pea and weighing 0.5 grams (0.018 oz) in humans. It is a protrusion off the bottom of the hypothalamus at the base of the brain, and rests in a small, bony cavity covered by a dural fold. The pituitary gland secretes nine hormones that regulate homeostasis.
