Why is adequate lighting necessary in a balanced aquarium?

Biology
1 answer:
deff fn [24]3 years ago
8 0

Answer:

A. Fish need light to see their food

Explanation:

B is incorrect because fish take in oxygen constantly to respirate. If they only took in oxygen when it was dark they would die.

C is incorrect because expelling CO2 is also a constant process as a part of the reactions that take part inside living organisms, so it happens constantly (a bit like B)

D is incorrect because plants need light for food (photosynthesis) and would most likely die or have stunted growth if left in the dark.

A is correct because when it is dark, fish rely on other senses to find food as most fish cannot see as well in the dark, therefore when they have light they can see their food more easily.

Hope this helped!

Natalka [10]

Answer:

To solve this question, it is necessary to consider the number of protein structures that have been empirically verified and the number of Open reading frames predicted from sequencing data

Explanation:

The most common methodologies used to determine protein 3D structure are nuclear magnetic resonance (NMR) and X-ray crystallography. Although both methods are efficient, the determination of 3D protein structures in physiological conditions is a time and cost-consuming task. Moreover, due to recent advances in bioinformatics and sequencing methodologies, the amount of protein Open Reading Frames predicted from sequencing data (especially obtained from Next Sequencing Generation studies) is many times higher. Indeed, less than 5% of sequenced proteins have an empirically validated 3D structure.
