Solutions
S1. Ans.(c)
Sol. Active transport, this is the only transport method that can move species against their concentration gradient (from low to high concentration). Facilitated diffusion only moves species down their concentration gradient from high to low concentration.
S2. Ans.(c)
Sol. The body’s primary building block for muscles, bone, skin and many other tissues is protein. So the slow growth of human body is caused due to the lack of protein.
S3. Ans.(c)
Sol. Rennin enzymes play an important role in helping young mammals to digest milk. Rennin enzymes are produced by the stomach cell.
S4. Ans.(a)
Sol. The average fat content in buffalo milk is 7.2%, while protein content in cow milk ranges from 4.2 to 4.5%. Apart from this it also contains, minerals and other essential nutritions.
S5. Ans.(d)
Sol. Casein is a phosphoprotein, which is found in milk, Phosphoprotein means any protein containing bound phosphate. The white colour of the milk is also due to the presence of casein. Some of the other proteins like lactoglobulin and lactalbumin are also found in milk. It is notable that milk is a complete diet, which contains approx. 3.3% protein.
S6. Ans.(b)
Sol. Alpha-keratin is a family of fibrous structural proteins. It is the key structural material making up the outer layer of human skin. It is the key structural component of hair, nails, hooves, and it provides the necessary strength and toughness for masticatory organs, such as the tongue and the hard palate.
S7. Ans.(a)
Sol. Haploids
S8. Ans.(b)
Sol. Linseed is a food and fibre crop that is grown in cooler regions of the world. The oil is extracted from its seed, known as lineseed oil, which is a very good source of omega 3 fatty acid, which is able to prevent the deposition of fat in blood vessels.
S9. Ans.(c)
Sol. Oxytocin has been best known for its role in female reproduction. It is released in a large amount during labour and after stimulation of the nipples. It is a facilitator for child birth and breast feeding. Oxytocin plays an important role in the neuroanatomy of intimacy, specifically in sexual reproduction of both sexes, in particular during and after childbirth. It is also known as love hormone and as the “bonding hormone”.
S10. Ans.(c)
Sol. Proteins
S11. Ans.(a)
Sol. Hyroid-stimulating hormone (also known as thyrotropin, thyrotropic hormone, TSH) is a pituitary hormone that stimulates the thyroid gland to produce thyroxine (T4), and then triiodothyronine (T3) which stimulates the metabolism of almost every tissue in the body.
S12. Ans.(a)
Sol. Bile is a fluid that is made and released by the liver and stored in the gallbladder. It is stored and concentrated in the gallbladder unit which is needed to digest food. In adults. The gallbladder measures approximately 8 centimetres in length and 4 centimetres in diameter.
S13. Ans.(a)
Sol. The average of normal temperature of human body is 98.4°F (37°C).
S14. Ans.(c)
Sol. Magnetic resonance imaging (MRI) is a test that uses magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body.
S15. Ans.(a)
Sol. Ergotism is a disease caused by consumption of contaminated grains. It is the effect of long-term ergot poisoning, traditionally due to the ingestion of the alkaloids produced by the Claviceps purpurea fungus that infects rye and other cereals.
