Read the following and answer any given below:The D vitamins are group of sterols that have a hormone like function. Vitamin D occurs naturally in fatty fish, liver and egg -yolk. Vitamin D deficiency causes a net demineralization of bone, resulting in rickets in children and osteomalacia in adults. Rickets is characterized by the continued formation of the collagen matrix of bone, but incomplete mineralization resulting in soft, pliable bones. In osteomalacia, demineralization of pre-existing bones increases their susceptibility to fracture insufficient exposure to daylight and/or deficiencies in vitamin D consumption occurs predominantly in infants and the elderly. Vitamin D deficiency is more common in the northern latitudes, because less vitamin D synthesis occurs in the skin as a result of reduced exposure to ultraviolet light.(i) Which of the following is fat soluble vitamin a.

What is the difference between smooth and rough endoplasmic reticulum? |
|
Answer» The endoplasmic reticulum is a delicate membranous structure contiguous to the nuclear membrane and present in the cytoplasm. It forms an extensive set of channels throughout the cell and is classified into rough or smooth types. The rough endoplasmic reticulum has a great number of ribosomes attached to the external side of its membrane. The smooth endoplasmic reticulum does not have ribosomes attached to its membrane. The main functions of the rough the endoplasmic reticulum is a synthesis and storage of proteins made in the ribosomes. The smooth endoplasmic reticulum plays a role in the lipid synthesis and, in muscle cells, it is important in the conduction of the contraction stimulus. |

Why is the flow of signals in a synapse from axonal end of one neuron to dendritic end of another neuron but not the reverse? |
|
Answer» When an electrical signal reaches the axonal end of a neuron, it releases a chemical substance. This chemical diffuses towards the dendrite end of next neuron where it generates an electrical impulse or signal. Hence, the electrical signal is converted into a chemical signal at the axonal end. Since these chemicals are absent at the dendrite end of the neuron the electrical signal, cannot be converted into chemical signal. |

Read the following and answer any given below:Transposons or jumping genes: The term ‘transposon’ was first given by Hedges and Jacob (1974) for those DNA segments which can join with other DNA segments completely unrelated and thus causing illegitimate pairing. These DNA segments are transposable and may be present on different place on main DNA. The transposons are thus also called Jumping genes. Hedges and Jacob reported them in bacteria. But actual discovery of these was made by Barbara Mc Clintock (1940) in maize and she named them as controlling elements or mobile genetic elements. For this work, she was awarded nobel prize in 1983.(i) Barbra Mc Clintock discovered jumping gene in a. Bacteria b. Human c. Eucalyptus d. Maize (ii). Who gave the term transposon a. Jacob and Monad b. Hedges and Jacob c. Barbra Mc Clintock d. Hugo-de-Vries (iii). Jumping genes are found in a. Eukaryotes b. Bacteriophage c. Bacteria d. Eukaryotes and prokaryotes (iv). The theory of jumping genes was propounded by or nobel prize for the concept of jumping gene was given to a. Mendel b. Morgan c. Barbra McClintock d. Hedges and Jacob (v). DNA elements which can switch their position are called a. Exons b. Introns c. Cistrons d. Transposons |

Find the number of roots of the equation \( 9 \sec ^{3} \theta-18 \tan ^{2} \theta-\sec \theta-16=0 \) in \( [0,2 \pi] \) |
|
Answer» \(9sec^3\theta - 18 tan^2\theta - sec\theta - 16 = 0\) ⇒ \(9sec^3\theta - 18 tan^2\theta+18 - sec\theta - 16 = 0\) \((\because tan^2\theta = sec^2\theta -1)\) ⇒ \(9sec^3 \theta - 18sec^2\theta - sec\theta + 2 = 0\) Let \(sec\theta = x\) Then \(9x^3 - 18x^2 - x + 2 = 0\) ⇒ \((x-2) (9x^2 -1) = 0\) ⇒ \((x -2) (3x -1) (3x + 1) = 0\) ⇒ \(x = 2 \,or\,x = \frac 13 \,or \,x = \frac{-1}3\) But \(x = sec\theta \in (-\infty, - 1]\cup [1, \infty)\) So, \(x\ne \frac{-1}3 \) & \( x\ne \frac 13\). \(\therefore x = 2\) \(\therefore sec\theta = 2\) is only root of given equation. |
