Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms including a high fever, headaches, and body aches typically occur two to
seven days after infection by the virus. SARS is more serious in elderly patients. This
information suggests that the reproductive cycle of the SARS virus is -
A. lysogenic, because the virus is a coronavirus.
B. lytic, because the virus causes respiratory illness
C. lysogenic, because the virus primarily affects older people.
D. lytic, because of the quick onset of symptoms after infection.

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
