Question 2 (1 point)
Severe acute respiratory syndrome (SARS) is an illness caused by a virus. 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 causes headaches
O b lytic, because the virus causes respiratory illness
O C lysogenic, because the virus primarily affects older people
O d lytic, because of the quick onset of symptoms after infection

Ineed asap with this question as well organisms evolve, through the process of natural selection, in ways that enable them to live successfully in their environments. choose three biomes or aquatic ecosystems and describe how abiotic factors have influenced the organisms that live there

Pixels are often referred to using dpi, or dots per inch. true\false

Match the following terms describing electrical events with the correct phases of the cardiac cycle. the ventricular muscle cells depolarize at the start of this phase. during this phase, na+ entry through the funny channels causes the pacemaker potential of sa nodal cells to gradually become less negative until it reaches threshold. the ventricular muscle cells repolarize right before this phase. the cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. a. isovolumetric relaxation b. ventricular ejection c. isovolumetric contraction d. ventricular filling
