Answer:
4. Methicillin is a strong antibiotic and MRSA developed resistance to it, making it harder to treat.
Explanation:
MRSA was first discovered in 1961. It's now resistant to methicillin, amoxicillin, penicillin, oxacillin, and other common antibiotics known as cephalosporins.
Viruses are made of one or more nuclei acid molecules surrounded by a coat protein or capsid. So the core of the virus will contain the viral genome. Some viruses' capsid maybe enclosed with an envelope derived from the host cell (the cell that the virus is infecting), and this envelope is also derived from the host cell membrane.
I believe the Answer is B but I could be wrong
By definition: Facilitated diffusion<span> is the process of spontaneous passive transport of molecules or ions across a cell's membrane via specific transmembrane integral proteins.~Google
An example, the only I can really think of:
Polar and large molecules normally can't cross the lipid bi layer using simple diffusion, it usually has to be </span>Facilitated diffusion
