Which organism would be MOST sensitive to acid rain?
A) bass
B) clams
C frogs
D) mayflies
Answer:
Explanation:
The correct answer is option B- Clams
It is very clear how acid rain is affecting our ecosystem. Plants, animals and other living organisms are effected including their habitat.
When acid rain enters soil, it leaches aluminium from soil particles and mixes it with soil. Aluminium level in water intoxicates the water content which is critical for the survival of water animals.
The critical PH level for clams is 6.
On land, nitrogen-fixing bacteria convert nitrogen from the atmosphere into ammonia. Other kinds of bacteria then convert the ammonia into nitrates that plants can use. How does this part of the nitrogen cycle on land compare to the process that occurs in the ocean?
A. Plants convert nitrogen into ammonia, which animals convert to nitrates.
B. Plankton, not bacteria, convert nitrogen into ammonia.
C. Plants convert nitrogen directly into nitrates.
D. Plankton, not bacteria, convert ammonia into nitrates.
Answer:During nitrification, ammonia (NH3) is oxidized and converted to nitrite and then to nitrate. This process is carried out by chemosynthetic bacteria (also known as nitrifying bacteria). That is, the energy released during nitrification is used to synthesize organic matter.
2. Denitrification occurs when bacteria in the soil, called denitrifying bacteria, use nitrates and convert them to nitrogen gas. Denitrification ensures that nitrogen is returned to the atmosphere.
3. Atmospheric nitrogen is fixed primarily with the help of bacteria. These bacteria act by forming nodules in the cortical areas of the roots of these plants, where they remove atmospheric nitrogen and convert it to the ammonia (NH3) used by the plants.
Explanation:
Answer: The correct answer is D. Plankton, not bacteria, convert ammonia into nitrates.
Explanation: Confirmed correct.
This chart shows characteristics of three different types of waves.

Describe the exchange of co2 and o2 the lungs
Explanation:
Co2 and O2 in the lungs are exchanged when alveoli send oxygen to the capillaries surrounding them to the nearby blood vessels which contain c02, and osmosis occurs where o2 is now in the vessels while co2 is now in the alveoli and therefore the lungs, and then the co2 is expelled out of the lungs.
