Answer:
Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.
The mitochondria creates carbon dioxide (CO2) as a waste product of cellular respiration (the process that makes energy for your body). Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell. It too is small and uncharged so it can pass through cell membranes easily.
These movements require no energy (in the form of ATP) on behalf of the cell.

Answer:
White
Explanation:
Some times when we look at some objects they appear to be different in color to us than their actual color. It may be due to several wavelength of light with different intensities is striking on our eye.
Remember, white is not a color it is just produced in response to combination of 3 or more than three colors like light.
The three colors that can be combined at full intensity to form a white color are called as primary colors. The most common set is
Red+Green+Blue= white
Zero intensity of each component gives darkest color and full intensity of any component give a white color.
Secondary colors can be produced by the addition of two colors such as;
Red+Green=Yellow
Red+Blue=Magneta
Green+Blue=Cyan

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.
