Answer:
temperature of water
Explanation:
an independent variable is the value that can be changed or controlled in a given model, they provide the "input" which is modified by the model to change the "output". in this example, the temperature is changed, affecting the fish's breathing rate.
Answer:
<u><em>DNA is made of repeating units called nucleotides.</em></u>
Explanation:
DNA can be described as a double helix molecule made up of long polymer chains of nucleotides. The nucleotides which are present in a DNA are:
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T)
The hydrogen bonds which occur in the pairing of nucleotides makes the double helix structure of DNA.
Adenine forms hydrogen bonds with Thymine.
Guanine forms hydrogen bonds with Cytosine.
The backbone of the DNA is made up of sugars and phosphates
Answer:
By covering the solution.
Explanation:
The anaerobic condition is maintained to ensure that the fermentation process is completed by covering the solution so that no oxygen enters the solution. Anaerobic conditions are necessary for the fermentation process because the anaerobic conditions allow the production of lactic acid, ethanol and carbondioxide gas from pyruvate. Without anaerobic condition, the fermentation process does not occur so that's why we can say that anaerobic conditions should be maintained for the fermentation process.
