NEED HELP. Whats the difference between clear-cut, Shelterwood, and uncut forests?

I need a detailed explanation cuz i don't understand

Clear cuts are areas from which every tree has been cut down and removed, in a shelterwood system the old stand is removed in a series of cuttings to promote the establishment of an essentially even-aged new stand under the shelter of the old one, and uncut forests are just your average wild woods, left alone and was never bothered with.

for a simpler clear cuts are clear areas, shelter wood are slight cuts, removing some trees for an environment such as parks and backyards, and uncut forests are wild forests that has no trees cut down.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
