E Correct answer
Explanation

 
  (a) Psychrophiles (Cold Loving) can grow at 0° C, but optimum is about 15° C.  (b) Psychrotrophs can grow at 0° C also, but optimum is 20 - 30° C – important in food spoilage.  (c) Mesophiles(Moderate temperature loving) grow best at moderate around 37° C – many pathogens fall in this category.   (d) Thermophiles (Heat Loving) have a growth optimum at around 60° C.   (e) Hyperthermophiles have growth optima of 80° C or higher (archaea).

Multiple choice

What is normal temperature of the human body?

  1. 98.7* F

  2. 96.7* F

  3. 98.4* F

  4. 94.8* F
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

While 98.6 degrees Fahrenheit is the modern medical standard, 98.4 degrees Fahrenheit was historically taught as the average human body temperature. Many competitive exams still use 98.4 as the standard correct answer.

Multiple choice

Which of the following statements is/are false? a. The clinical thermometer range is between 35 degree celsius to 42 degree celsius. b. Light coloured objects, absorb more heat radiations than the dark coloured objects. c. A clinical thermometer has a kink that prevents the mercury to rise or fall.

  1. Only a

  2. Only a and b

  3. Only b

  4. Only b and c

  5. Only c
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Light coloured objects absorb more heat radiations than the dark coloured objects, is a false statement. This is the correct option.  Dark coloured objects absorb more heat radiations than the light coloured objects, is the correct statement.

Multiple choice

Consider the following cities:

  1. Canton 2. Peking
  2. Singapore 4. Tehran The correct sequence of these cities, in ascending order of average annual temperature, is

  1. 1, 3, 2, 4

  2. 2, 4, 1, 3

  3. 3, 1, 4, 2

  4. 4, 2, 3, 1
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Peking (Beijing) is the furthest north and has the lowest average temperature. Tehran is also relatively northern. Canton (Guangzhou) and Singapore are closer to the equator, with Singapore being the closest and thus having the highest average annual temperature.

Multiple choice

The range of a common thermometer used in laboratories is between

    • 10 degree C and 110 degree C

  2. 10 degree C and 100 degree C
    • 10 degree C and 10 degree C

  4. 0 degree C and 100 degree C
    • 110 degree C and 110 degree C
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This is the correct option. The range of a common thermometer used in laboratories is between - 10 degree C and 110 degree C.

Multiple choice

Celsius thermometer cannot measure higher temperatures like that of a candle flame because in that case,

  1. the thermometer will break due to excessive contraction of the mercury

  2. the thermometer will break due to excessive expansion of the mercury

  3. the thermometer will break due to the glass of thermometer getting too hot

  4. the thermometer will break due to the freezing of mercury

  5. the thermometer will break due to the melting of the capillary tube

B Correct answer
Explanation

This is the correct option. Celsius thermometer cannot measure higher temperatures like that of a candle flame because in that case, the thermometer will break, due to excessive expansion of the mercury.
