Multiple choice botany the living world archaebacteria the three domains of life classification of microbes

A few organisms are known to grow And multiply at a temperature of $100 - {105^ \circ }C$ they belong to

  1. Thermophilic sulphur bacteria

  2. hot spring blue green agae

  3. methanogenic archaebacteria

  4. Marine archaebacteria
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Thermophilic sulphur bacteria can survive at high temperatures between 41 and 122$^o$C and an optimum growth temperature which is higher than 75$^o$C. Hot spring blue-green algae have an optimum growth temperature of 45$^o$C. Methanogenic archaebacterium grows at an optimum temperature of 35-40$^o$C. Some marine archaebacteria are extreme thermophiles and grow at temperatures of 65- 80$^o$C. 

So, the correct answer is 'Thermophilic sulpher bacteria'.

Multiple choice geography in the land of kerala introduction to metallurgy occurrence of metals study of kerala

The temperature of the slag zone in the metallurgy of iron using blast furnace is:

  1. 1200-1500$^0C$
  2. 1500-1600$^0C$
  3. 800-1000$^0C$
  4. more than 2000$^0C$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Slag is the fusible compound formed by the combination of flux and gangue.


$\underset{Flux}{CaO}+\underset{Gangue}{SiO _2} \rightarrow \underset{Slag}{CaSiO _3}$

At the temperature of the slag zone in the metallurgy of iron using blast furnace is $800^oC – 1000^oC$.

Option (C) is correct.

Multiple choice evs atmosphere- wind weather, climate and adaptation of animals to different climates climate and weather weather, climate and adaptations of animals to climate

The air temperature is $45^{o}F$,  the wind is blowing at $30 MPH$, and the wind chill temperature is $15^{o}F$. These conditions would be equivalent to:

  1. $A\, 15^{c}irc\, F$ air temperature and 0 MPH winds
  2. $A\, 30^{o}\,F$ air temperature and 45 MPH winds
  3. $A\, 30^{o}\,F$ air temperature and 15 MPH winds
  4. $A\, 15^{o}\,F$ air temperature and 30 MPH winds
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

By definition, the wind chill temperature of 15 degrees F is the temperature at which a person would feel the same level of cold if there were no wind (0 MPH).

At what time during a 24-hour day would a radiation temperature inversion best be developed?

  1. At sunset

  2. Near sunrise

  3. Toward the end of the morning

  4. Between 2 and 5 pm when the air temperature reaches a maximum
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A radiation temperature inversion occurs when the ground cools rapidly at night, cooling the air in contact with it. This is most pronounced near sunrise, after the ground has been losing heat all night.

What is the ideal temperature required for the cultivation of coffee?

  1. $10^0C-15^0C$
  2. $10^0C-18^0C$
  3. $15^0C-20^0C$
  4. $15^0C-28^0C$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Ideal climatic conditions to grow coffee are related to temperature and rainfall; temperatures in the range of 73 °F (23 °C) and 82 °F (28 °C) with rainfall incidence in the range of 60–80 inches (1.5–2.0 m) followed by a dry spell of 2–3 months suit the Arabica variety.

What is the optimum temperature required for the production of Maize?

  1. $18^\circ$ to $22^\circ$
  2. $20^\circ$ to $24^\circ$
  3. $21^\circ$ to $27^\circ$
  4. $30^\circ$ to $37^\circ$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Maize is grown in temperatures between 21°C and 27°C during the day and around 14°C during the night. But the most important factor is the 140 frost-free days. The crop is very susceptible to frost; therefore, its cultivation in temperate latitudes is limited.
