Answer:
The correct option is B. The stage of a virus where it is activated to perform the function for which it was intended is referred to as the triggering phase.
Explanation:
The life cycle of a virus consists of the following stages:
The Dormant phase:
In this phase, the virus doesn't take any action. It just manages to get into the system or software.
The Propagation phase
In this phase, the virus makes copies of itself.
The Triggering Phase
In this phase, the virus performs its function.
The Execution Phase
In this phase, the destruction made by the virus can be seen.
<span>C. Single events or several causes working together to produce extinction in a short period is referred to as mass extinction.
Example:
</span>Destruction of forests, mountains, and bodies of water to satisfy human needs result to the imbalance of nature which also give rise to global warming.
Animals and plants have lost their habitats. They lost their means to live. They lost their food sources and they suffer and die because of humans irresponsible acts.
hope I helped!!
Answer:
The correct answer is - option b. to generate a protein with a run of consecutive glutamines.
Explanation:
The initiation code AUG is the code for methionine and as well as the initiation code for the particular protein or peptide chain. In this protein, there is a repeat of CAG is increased with the initiation code so, even though they are in zero reading frame they code for their amino acid which is glutamine.
So. an increased number of CAG repeats will result in a protein with the a run of consecutive glutamines.
Answer:
We will produce lactate/lactic acid through fermentation.
Explanation:
During strenuous activities, muscle cells do not sufficient supply of oxygen to meet the energy requirements. As a result, anaerobic respiration occurs to temporarily supply energy and lactic acid is produced instead of carbondioxide and water.
Lactic acid accumulates in muscles and eventually preventing further contraction. The muscle cells are said to have incurred an 'oxygen dept' since they have used up more energy than was possible from the oxygen supplied to them. The largest amount of lactic acid a body of a trained athlete can tolerate is about 127grams, and the largest tolerable oxygen is about 16 litres.
