Which one of the following group of organisms has the largest number of species?
It has long been recognized and documented that insects are the most diverse group of organisms, meaning that the numbers of species of insects are more than any other group. In the world, some 900 thousand different kinds of living insects are known.
Which of the following is not a pesticide?
Ephedrine is asympathomimetic amine commonly used as a stimulant, appetite suppressant, concentration aid, decongestant, and to treat hypotension associated with anaesthesia
Which one of the following plant products has genes of a bacterium?
An organism that is generated through genetic engineering is considered to be agenetically modified organism (GMO). The first GMOs were bacteria in 1973 and GM mice were generated in 1974. Insulinproducing bacteria were commercialized in 1982 and genetically modified food has been sold since 1994. Glofish, the first GMO designed as a pet, was first sold in the United States December in 2003 The Bt brinjal is a suite of transgenic brinjals (also known as an eggplant or aubergine) created by inserting a crystal protein gene (Cry1Ac) from the soil bacterium Bacillus thuringiensis into the genome of various brinjal cultivars.
Which of the following is a presumptive
serological test for enteric fever or undulant fever?
The Widal test is a presumptive serological test for enteric fever or undulant fever whereby bacteria
causing typhoid fever are mixed with serum containing specific antibodies obtained from an infected
individual. In case of Salmonella infections, it is a demonstration of the presence of O-soma false-positive
result. Test results need to be interpreted carefully in the light of past history of enteric
fever, typhoidvaccination, and the general level of antibodies in the populations in endemic areas of the
world. Typhidot is the other test used to ascertain the diagnosis of typhoid fever.
Cholesterol, from the Ancient Greek chole- (bile) and stereos (solid) followed by the chemical suffix -
ol for an alcohol, is an organic molecule. It is a sterol (ormodified steroid), a lipid molecule and
is biosynthesized by all animal cells because it is an essential structural component of animal cell
membranes that is required to maintain both membrane structural integrity and fluidity. Cholesterol
enables animal cells to (a) not need a cell wall (like plants & bacteria) to protect membrane integrity/cellviability
and thus be able to (b) change shape and (c) move about (unlike bacteria and plant cells which
are restricted by their cell walls).
Which one of the following diseases are caused due to defect in a gene?
Haemophilia (also spelled hemophilia in North America, from the Greek haima? 'blood' and philia 'love') is a group of hereditarygenetic disorders that impair the body's ability to control blood clotting orcoagulation, which is used to stop bleeding when a blood vessel is broken.
Containers for keeping strong acids are made of
Hydrochloric acid should never be transported in other than a plastic
coated glass container, accurately labeled, and properly stored within
the vehicle to prevent shifting, spillage, or breakage. Containers
of hydrochloric acid carried in vehicles in warm climates should be
placed in coolers to protect them from excessive heat. Although
hydrochloric acid has a boiling point of 110 degrees C (230 degrees F)
it should be transported at room temperature to minimize a buildup of
gas pressure in the container.
In birds, sound is produced by
Nearly all birds produce sound through an organ unique to birds, the syrinx. In many songbirds,
the syrinx is not much bigger than a raindrop. Extremely efficient, it uses nearly all the air that
passes through it. By contrast, a human creates sound using only 2% of the air exhaled
through the larynx. Birds whose syrinx is controlled by only one set of muscles have a limited
vocal range. This Song Sparrow, using several pairs, can put forth a cascade of trills and notes.
Which one of the following has the highest pH?
While strength of acidity is measured according to pH, with most wines having a pH between 2.9 and 3.9. A pH value of 7 means a substance is neutral. A lower value indicates acidity, and a higher value is a sign of alkalinity. Lemon's pH value is 2.5, coffee is pH 5.0-6.5, milk is about 6.2, soapy water is about 7 to 10, and beer is about 4.5.
