Answer: B
Explanation: By most estimates, catalytic converters fitted inside the exhaust pipe of a gasoline-operated car convert over 90% of hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) from the engine into less harmful carbon dioxide (CO2), nitrogen and water vapour.
The colourless colonies are only the gram-negative bacterium that will grow as the selective media Eosin Methylene Blue (EMB) followed by mannitol salt agar (MSA), which will only allow one type of microorganism to grow.
Eosin Methylene Blue (EMB) agar is a differential microbiological medium that gives a colour indicator to distinguish between organisms that digest lactose and those that do not while significantly inhibiting the development of Gram-positive bacteria. In laboratories, the selective medium is crucial for differentiating gram-negative microorganisms.
Both EMB (Eosin methylene blue) and Mannitol Salt Agar (MSA) are selective in that they only permit the growth of Gram-negative bacteria.

Answer:
Large rain events
Explanation:
They can also rapidly circulate the water in a lake or pond, causing changes in the position of oxygen rich water in a short period of time. This quick 'turnover' of the water can quickly decrease the amount of oxygen available to fish, essentially causing them to suffocate.

As the cardiac muscle gets stronger, the amount of blood pumped with each beat increases which in turn makes the heart more efficient overall. As a result, we can infer that as the cardiac muscle gets stronger, the heart rate will decrease since it is able to pump more blood with each beat
