Answer:
A differential medium
Explanation:
Bacteria require nutrients for growth, and in order to culture (grow) them and study their characteristics, different types of media are used.
A selective media is used to grow a particular group of organism while suppressing another. So a selective media usually has an inhibitory agent, which will inhibit the growth of the undesired group. An antibiotic can be added to a medium to make it selective.
A general purpose medium as the name implies can be used to grow any group of bacteria. It has no inhibitory agent and indicator that differentiates between organisms. An example of general purpose media is nutrient agar
.
A non-synthetic media is made from natural ingredients.
A differential media differentiates between groups of organisms. Example of differential media is MacConkey agar and Mannitol Salt agar. On MacConkey agar, lactose fermenting bacteria turn pink while non-lactose fermenting bacteria are colorless.
On Mannitol Salt agar, mannitol fermenting bacteria turn yellow while non-mannitol fermenting bacteria are colorless. Mannitol Salt agar is also a selective medium. It has a high salt concentration which inhibits certain organisms.
Leaves in areas of low humidity have a steeper concentration gradient so water diffuses out of the leaf fast.
<h3>What is humidity?</h3>
Humidity is used to determine the concentration of water vapour that is available in the air.
when the vapour is high there is high relative humidity when the vapour is low there is low relative humidity and water leaves the surface of leaf fast.
Therefore, Leaves in areas of low humidity have a steeper concentration gradient so water diffuses out of the leaf fast.

eubacteria and archaebacteria
<span>Through the digestion system, water is mainly absorbed in the large intestine. This task is devoted to the system of gastrointestinal tract, in which you have to orientate. The only correct answer is large intestine that is the largest part of both the whole tract and digestive system and actually this is the point where water, as leftover, is absorbed.</span>
