Answer:
constants.
Explanation:
Climate-controlled room are almost indoor and are kept with stable temperatures and also with stable humidity levels.
<u>In biological experiments, it used to establish constant parameters like temperature, humidity, exposure to different things, growth of organisms and etc.</u>
These rooms provide better shelf life and thus better results.
Answer:
Autotrophs.
Explanation:
Autotrophs may be defined as the organisms that can prepare their own food. The autotrophic organism do not depend on the other organisms for their food.
Plants are considered as autotrophs because they can prepare their own food. The autotrophs uses sunlight to convert the water and carbon dioxide into food and oxygen.
Thus, the correct answer is option (3).
Answer:
Ratio = 
Explanation:
Side of a cube, a = 20 µm

The surface area of a cube, A = 6a² (a is side of the cube)
The volume of a cube, V = a³
The ratio of the surface to volume ratio of the cell will be given by :

So, the ratio of the surface to volume ratio of the cell
.
Answer:

Hypertonic
having a higher osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid
Hypotonic
having a lower osmotic pressure than a particular fluid, typically a body fluid or intracellular fluid.
