  • Question 1
    4 / -1

    Total number of genes are found in human genome are

    Solution

    Human genome is estimated to have 30,000 genes. Each average gene consisting of 3000 bases. The human genome thus has over 3 billion nucleotide pairs.

     

  • Question 2
    4 / -1

    SNPs stands for

    Solution

    Single nucleotide polymorphism is a small genetic change that occurs within a DNA sequence. It can also be defined as replacement of one nucleotide with any of the other 3 nucleotides.

     

  • Question 3
    4 / -1

    What is the percentage of glomerular filtrate that is excreted through urine?

    Solution

    The daily volume of glomerular filtrate in adults is 150 liters in females and 180 liters in males. More than 99% of the glomerular filtrate returns to the bloodstream via tubular reabsorption thus only less than 1% is excreted through urine.

     

  • Question 4
    4 / -1

    Blood borne ADH binds to _______ receptor.

    Solution

    Blood borne ADH binds with its receptor present on the basolateral membrane of a cell in the distal or collecting tubule. This binding activates the cAMP secondary-messenger system within the cell. cAMP increases the opposite luminal membrane’s permeability to water by promoting the insertion of ADH-regulated water channels into the membrane.

     

  • Question 5
    4 / -1

    RBC count increases under which condition: 

    a) Muscular exercise 

    b) High altitude due to low oxygen 

    c) Rise in temperature of environment 

    d) Release of erythropoietin hormone 

    The correct answer is:

    Solution

    Erythropoietin is a hormone that stimulates RBC formation. At high altitude and during exercise the body is in need of oxygen, so more RBC is manufactured.

     

  • Question 6
    4 / -1

    Which of the following acid has highest solubility?

    Solution

    Solubility of acids gradually decreases with increase in their molar masses. Solubility of lower members of carboxylic acids is due to H-bonding. Branching in chain also decreases the solubility. Thus, acetic acid has the highest solubility in water among the given compounds.

     

  • Question 7
    4 / -1

    Which of the following compound has highest melting point?

    Solution

    Melting point of carboxylic acid increases with increasing molar mass. Melting point of carboxylic acids containing even number of carbon atoms is higher than the next lower and higher member containing odd number of carbon atoms. Thus butanoic acid has the highest melting point among the given carboxylic acids.

     

  • Question 8
    4 / -1

    The compound which has the highest boiling point is

    Solution

    Due to the presence of H-bonding, boiling point of carboxylic acids is higher than that of corresponding aldehydes, ketones, ethers or even alcohols of comparable molar masses. Thus acetic acid has the highest boiling point among the given compounds.

     

  • Question 9
    4 / -1

    Which of the following compounds evolves CO2 on reaction with weak base such as bicarbonate?

    Solution

    Carboxylic acids can react with weaker bases such as carbonates and bicarbonates to evolve CO2

    R-COOH + NaHCO3 →RCOONa + CO2↑+ H2

    This reaction is used to detect the presence of carboxyl group in an organic compound.

     

  • Question 10
    4 / -1

    In a farm in order to provide water to the fields a farmer uses an electric motor that draws 120 A of current while operating at 240 V. What will be the power of this motor?

    Solution

    Power Consumed = Current Drawn X Voltage 

    = 120 X 240 

    = 28.8 kW

     

  • Question 11
    4 / -1

    A person has electric motors drawing current 15 A and generating power of 18 kW. If he wishes to generate 9kW power how many motors should he connect and how?

    Solution

    Power generated in series = p/ n

    Power generated in parallel = nP

    Therefore, when we connect two motors in series, 

    Power generated = 18/2 = 9kW

     

  • Question 12
    4 / -1

    When a circular loop is pulled sideways through a uniform magnetic field B in such a way that the magnetic field B penetrates through only bottom half of this circular loop then,

    Solution

    The motion does not change the magnetic flux through the loop. The magnetic flux is constant with respect to time. Hence, there is no induced current in the loop.
