The mass of virions in the Pacific Ocean. Introduction: Viruses can be defined as acellular organisms that are obligate intracellular parasites. Viruses lack any cellular organelles but have only genetic material and protein-lipid core. These organisms cannot replicate by themselves, so they require a host cellular machinery to reproduce.

Question

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

a typical eukarytic cell has a diameter of 50 microns while a corona virus particles has a diameter of 100 nanometers. how many virus particles could be packed into the volum of the typical eurkaryotic cell? (assume the cell and the virus are spherical - V = 4/3 π R^3 and that the particles can use 100% of the space in the cell)

The SIR model of pandemics (such as COVID-19) considers three variables: S (those susceptible to the disease) I (those infected with the disease), and R (those recovered or removed from the illness). This model has a system of three differential equations, one for the derivative of each variable. We viewed the video entitled "The Coronavirus Curve - Numberphile," and we also rebuilt this model in Geogebra ourselves. That model includes two constants, "transm" and "recov:" use Ct instead of "transm," and use cr instead of "recov." In Geogebra, we could tweak these values. a. In this system, what is the equation for S'(t) = dS/dt? b. In this system, what is the equation for I'(t) = dI/dt? c. In this system, what is the equation for R'(t) = dR/dt? d. Who made this video?
