Answer:

Option C, operate the automatic safety controls

Explanation:

A heat system must be inspected for the following automatic safety features -

A) automatic fire-extinguishing system - a system  that automatically detects a fire and discharges something to stop it

B) Automatic sprinkler system - A sprinkler system for fire-protection purposes

c) humidistat - to automatically control relative humidity

d) Automatic panel board

e) thermostat to  automatically  maintain temperature

f) an automatic water pump  for removal of waste water

Hence, the automatic systems must be verified at  the time of inspection for ensuring safety at the time of crisis.

Hence, option C is correct

You are given a 1 liter bacterial culture in exponential stage of growth. The generation time of the bacteria is known to be 30
nydimaria [60]

Answer:

Option-A

Explanation:

A bacteria divides by binary fission which divides a parent bacteria into the two daughter cells and generation time refers to the average time difference between two consecutive generations.

The bacterial cell grows by the exponential function that is by 2^{number of generation} x initial population of bacteria.

In the given question,

<u>Initial population</u>

the initial population of bacteria - 2x 10³ per ml

So per liter, the bacterial population will be 2 x 10 ⁶

<u>Generation time</u>

1 generation time of bacteria is 30 min.

so 5 hours will have- <u> </u>\frac{300}{30}= 10 generations

<u>New bacterial population</u>

Using formula<u>  </u>2^{number of generation} x initial population of bacteria

2^{10} x (2 x 10⁶)

= 1048 x (2 x 10⁶)

2048 x 10⁶

Thus, Option-A is the correct answer.

Write a short story describing the application of the system of classification of living creatures
Citrus2011 [14]
All living creatures are classified into systems and sub-systems based on their similar characteristics. They are divided from bigger groups into smaller groups based on the detail of their similarities i.e. how they look, move, reproduce and how they relate to each other. A practical way of understanding the classification of living organisms is that organisms are linked to other similar organisms via family trees. The classification of all living creatures includes at least four levels: order, families, genus and species.
