Answer:
b: time
Explanation:
When meteorologists need to make a forecast they analyze different measurements in order to accurately make a forecast, these include patterns of winds, pressure, pressure change, temperature, humidity, clouds, and hygrometers. From the answers provided the one measurement that is not used is time. Mainly due to the fact that weather does not depend on the time of day, and any type of weather can be present at any time if the right circumstances exist.
The EMB (Eosin Methylene Blue) agar is a selective and differential agar medium. It contains sucrose and lactose as fermentable substrates together with Eosin Y and methylene blue dyes which in combination gives the agar its characteristic color when prepared and serves as a pH indicator as well as an inhibitor of growth of Gram-positive bacteria. Hence, it is primarily used to isolate Gram-negative fecal coliforms while some positive fecal coliforms such as Staphylococci are also able to grow.
These coliforms are of two types:
- Lactose or sucrose fermenting coliforms form metallic sheens on the agar as a result of acid production and the response of the indicator to the increased acidity.
- Non-lactose/sucrose fermenters are only able to produce acid by protein deamination. Hence they either form colorless or pinkish colonies on the agar
On the other hand, Mannitol salt agar is a selective and differential agar medium that is primarily used to isolate Staphylococcal bacteria. The presence of sodium chloride in the medium makes it a partial or complete inhibitor of other bacteria.
Hence, an unknown bacterium that forms colorless colonies on EMB will either be a non-lactose fermenting, Gram-negative coliform that will hardly grow on Mannitol salt agar, or a Gram-positive fecal Staphylococcus.
Staphylococci bacteria are of two types:
- Coagulase-positive will form yellow colonies on the Mannitol salt agar.
- Coagulase-negative will form red colonies on the Mannitol salt agar.

Explanation:
Gelatin also referred to as hydrolyzed collagen.collagen is a structural protein in animal and undergoes hydrolysis to form gelatin.
Gelatin appears as a translucent, colorless and flavorless food ingredient used as gelling agents in food, drugs and cosmetics.
When dry it is bristle and becomes gummy when moist.
Gummy bears are known for their chewiness and gelatin gives them the chewiness.
