Answer:
Explanation:
In a lake, oxygenic phototrophs produce new organic material as well as O₂. If primary production rates are very high, the resultant excessive organic matter production can lead to bottom-water O₂ depletion from respiration and the development of anoxic conditions. This in turn stimulates anaerobic metabolisms, including anaerobic respirations and fermentations.
Organic matter that is not consumed in surface layers sinks to the depths and is decomposed by anaerobes.
Answer:
signaling processes
Explanation:
Neurons within the brain are constantly processing and transmitting information. Electrical impulses that pass from one neuron to another consume a lot of energy. So, sending, receiving and processing the signals are the main events of brain energy expenditure. Neurons also use the energy for the maintenance of themselves and the surrounding glial cells.
Glucose is the main energy source in the brain.
Answer:

Explanation:
Given
There are three stop codon
TAA, TAG, TGA.
Out of 64 available codons, 3 are stop codon thus the remaining are non-stop codon.
So the probability of choosing a non stop codon is

Let us suppose the number of trials are "x" then the probability of choosing a non stop codon is

Probability of choosing a stop codon is equal to
probability of choosing a non stop codon
