Ghella [55]3 years ago
5 0

Answer:

The correct answer is "The ammonia is controlled with a filter that uses two type of bacteria."

Explanation:

  • The Biosphere on earth is composed of all the ecosystems, while each ecosystem is composed of the abiotic and biotic components and their mutual interactions. Aquarium is an example of aquatic ecosystem.
  • Abiotic components constitute the non-living part of the ecosystem.
  • Biotic components constitute the living part of the ecosystem.
  • In the aquarium,
  1. The abiotic components include the air, water, heat, minerals, sunlight, fluorescent light.
  2. The biotic components include the aquatic plants, aquatic animals and  the bacteria (in the filter attached to the aquarium).
  • These bacteria are responsible for fixing dissolved nitrogen gas present in the water of the aquarium to ammonium and are called nitrogen-fixing bacteria.
  • Free living bacteria like cyanobacteria or blue-green algae are examples of nitrogen-fixing bacteria.
  • Fixation of dissolved nitrogen gas to ammonium and then conversion of ammonium to nitrites and nitrates (done by other bacteria) is essential because plants (terrestrial or aquatic) can use only  nitrates as the source of nitrogen for the purpose of metabolism.

Organic molecules derived from vitamins that act as helpers are called
AysviL [449]
Coenzymes

Coenzymes are small organic molecules that, themselves, do not function as catalysts (i.e. enzymes) but aid the latter in carrying out their functions. Enzymes are biological catalysts, which means that they allow reactions to occur at lower activation energies. In a way, enzymes help to "speed up" chemical reactions. 

Coenzymes are mostly derived from vitamins. Examples include TPP from Vitamin B1 (thiamine), FAD from Vitamin B2 (Riboflavin), and NAD+ from Niacin.

If scientists are wrong about Earth's age based on radioactive material and the decay rates are really much faster, how would nu
kupik [55]

Nuclear power plants use the energy originating from the splitting or uranium atoms to produce steam, which in turn drives a turbine generator.

The main problem with this form of energy production is the byproduct from the nuclear reactors known as radioactive waste. Although it is no longer efficient for the energy production, this waste is still radiating large amounts of heat and radiation. Thus, they are very hazardous as they are fatal on direct exposure and can contaminate the environment.

Due to the extremely long half-life, long term storage for this waste is extremely problematic.  However, if the decay rates were much faster, then the half-life would also be much shorter. Thus, short term storage solutions could be found.

Excepting the nuclear waste and the potential accidents (which are minimized in modern plants), nuclear energy does not immediately affect the climate on earth. With short half-lives, nuclear energy would perhaps become more popular than solar or wind energy as it is more reliable and efficient.
