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.

sergey [27]

Some proteins do indeed need assistance during the folding process. the general term used for the proteins that help other proteins fold is Chaperones.

<h3>What are Chaperones?</h3>
  • Chaperones are proteins that help big proteins or macromolecular protein complexes fold or unfold conformationally. There are different groups of molecular chaperones, all of which have the same purpose: to help big proteins fold properly during or after synthesis as well as following partial denaturation.
  • Protein translocation for proteolysis involves chaperones as well. The bulk of molecular chaperones aid in protein folding by binding to and stabilizing folding intermediates up until the polypeptide chain is entirely translated, rather than providing any steric information for protein folding.
  • Based on their target proteins and location, chaperones have different unique modes of operation.

In the 1950s, when Watson and Crick were working on their model of DNA, which concepts were well accepted by the scientific comm
julia-pushkina [17]

Answer:

Option (1), (2) and (3).

Explanation:

DNA is the genetic material of all the living organisms present on earth. The DNA contains the nitrogenous bases, pentose sugar and the phosphate group. DNA strands runs in the opposite direction and shows polarity.  

Watson and Crick explain the structure of DNA based on the X ray diffraction produced by Rosalind. According to the structure, chromosomes are present in the nucleus and contains the DNA and wrapped around the proteins. The genes is considered as the functional segment of DNA.

Thus, the correct answer is option (1), (2) and (3).

Margarita [4]
Many cells working together forms a tissue.  Many tissues working together forms organs. Many organs working together forms organ systems.  So it goes from general to most specific.  Organ systems are needed in order for life.  This proves that cells are the most basic units of life.

What role does natural light exposure during the day play in improving sleep? it helps to regulate circadian rhythm. it discoura
yuradex [85]

Answer: It helps to regulate circadian rhythm

Exposure to natural light during the day helps regulate the circadian rhythm, which improves sleep pattern. The term circadian rhythm refers to our biochemical, physiological and behavioral processes in approximately 1 full day cycle. Circadian rhythm plays an important role in controlling when we fall asleep and when we wake up.

During day light, the secretion of melatonin or sleep hormone is suppress by melanopsin that keeps people awake and alert. Nevertheless, during nighttime, melanopsin stimulates the release of melatonin to signal sleeping time. Therefore, this hormone works the entire day and has direct effect on the circadian rhythm, which acts as a regulator of our biological clock.
