Biology Question Bank – 137 MCQs on “Applied Biology” – Answered!

Industry
137 Questions with Answers and Explanations on “Applied Biology” for Students.1. In crop movement programme, haploids are important because they (a) require one half of nutrients Image Source: northwesternflipside.com ADVERTISEMENTS: (b) are helpful in study of meiosis(c) grow better under adverse conditions(d) form perfect homozygous. ADVERTISEMENTS: Answer and Explanation:1. (d): in crop movement programme, haploids are important because they form perfect homozygous lines. Homozygous are the pure line selection plants resulting from self pollination. In this way, considerable homozygosity is obtained. Haploids are those plants which possess a gametophytic number of chromosomes. Haploids are used in plant breeding, especially for the production of homozygous plants and in their studies in the detection of mutation.2. Which ones produce androgenic haploids in anther cultures?

69 Questions with Answers and Explanations on Mendelian & Post Mendelian Genetics for Biology Students.1. Which contribute to the success of Mendel? (a) qualitative analysis of data Image Source: upload.wikimedia.org ADVERTISEMENTS: (b) observation of distinct inherited traits(c) his knowledge of biology(d) consideration of one character at one time. ADVERTISEMENTS: Answer and Explanation:1. (c): Consideration of one character at one time contribute to the success of Mendel. Mendel’s contribution was unique because of his methodological approach to a definite problem, use of clear cut variables and application of mathematics (statistics) to the problem. Using pea plants and statistical methods, Mendel was able to demonstrate that traits were passed from each parent inheritance of genes.2. Two linked genes a and b show 20% recombination, the individuals of a dihybrid cross between ++/+…

Useful Notes on Electrovalent, Covalent and Hydrogen Bond

Biology
The manner in which atoms are bounded together is of critical importance in all biochemical reactions. Three kinds of bonds may be briefly considered here: electrovalent, covalent and hydrogen. 1. Electrovalent bond: An electrovalent bond is formed by the transfer (not sharing) of one or more electrons from the outer shell of one element, say sodium, to another, say chlorine. Sodium has a single (“extra”) outer electron; it lacks seven of the eight electrons needed for stability of his outer shell. Chlorine has seven outermost electrons; its outermost shell is one electron short of complete stability. Image Source: 2012books.lardbucket.org ADVERTISEMENTS: Each atom would gain greater stability by combining with the other. The sodium tends to give up its single electron; the chlorine tends to saturate its outer electron shell by…

(1988, 89) ADVERTISEMENTS: Answer and Explanation:1. (a): Acid rain refers to the precipitation with a pH of less than 5. It is a mixture of H2SO4 and HNO3, the ratio of the two acids vary depending on the relative quantities of sulphur oxides and nitrogen oxides present in the atmosphere. These oxides are mainly produced by combustion of fossil fuels, smelters, industries, power plants, automobile exhausts etc.2. Which one is not a…

Humming birds and Hawk illustrate (a) convergent evolution Image Source: farm4.static.flickr.com ADVERTISEMENTS: (b) homology(c) adaptive radiation(d) parallel evolution. ADVERTISEMENTS: Answer and Explanation: 1. (c): Adaptive radiation in evolution was developed by H.F. Osborn in 1898. It is also known as “Divergent evolution” It is development of different functional structures from a common ancestral form. Examples as mentioned in the question.Whereas development of similar adaptive functional structures in unrelated groups of organism is adaptive convergence = convergent evolution, e.g. wings of insect, bird and bat. When convergent evolution is found in closely related species, it is called “Parallel Evolution”. Example: development of running rabbit in deer (2 toed) and horse (1 toed).2.
