Answer:
a. 30 cm³
b. 4.33 g/cm³
Explanation:
a Volume of the object = l*w*h
l = 5 cm
w = 2 cm
h = 3 cm
Volume of object = 5*2*3 = 30 cm³
b. Density of the object = mass of the object / its volume
Mass of object = 130 grams
Volume = 30 cm³
Density of the object = 
Answer:
The envelope come from the host cell membrane as the virus leaves the host cell
Explanation:
A virus is an organism that is incapable of replicating on its own without infecting a living host. A virus consists of a genetic material (DNA or RNA) , a protein coat called CAPSID, and sometimes some viruses possess an envelope, which is an outer covering or enclosure. Viruses that possess this envelope are referred to as ENVELOPED VIRUS.
The virus lacks the ability to produce any structure, hence, they gain this envelope made of phospholipid from the cell membrane of the host they infect. During the infection cycle of a virus, a process called budding enables a portion of the host's plasma membrane to cover or encapsulate the virion cells, hence, making them enveloped in the process.
