Answer:
cold with high salt content
Answer:
As the variables are not given, let us help with general explanation on manipulated variable.
Explanation:
A manipulated variable is an independent variable. In a scientific experiment, an independent variable can be described as a variable which can change naturally or which is changed by the researcher to check its effect on the dependent variable. The dependent variable is the variable which is under study and being tested.
For example, to check the difference in photosynthesis rate by light, the amount of light will be the independent variable and the rate of photosynthesis will be the dependent variable.
The rate and direction of reactions are greatly influenced by the Law of Mass action or molecular concentration because they relate to the same principle
Answer:
lytic, because of the quick onset of symptoms after infection
Explanation:
As seen in the question above, the SARS virus tends to develop symptoms very quickly when it is infecting a person. This speed in the development of symptoms is a characteristic of the lytic cycle, in relation to the reproductive cycle of viruses. This is because in the lytic cycle, a virus can infect many cells at once, which accelerates the development of the disease. This cycle allows the virus to use all of the cell's biological machinery to reproduce more copies of the virus. When these copies are ready, the virus causes the destruction of the host cell and the release of new viruses to other cells, where the whole process will be repeated. This is all done very quickly.
The lysogenic cycle does not cause the rapid infection of thousands of cells, since it is necessary that there is an adaptation between the DNA of the cell and the DNA of the virus. This slows down the infection process and, therefore, symptoms appear more slowly.
