You place them on the windowsill.

Frequently is used the ethylene oxide.
Pears ripen pretty quickly, but if you put in a bag with a banana or an apple the gases from these fruits will make the pear ripen quicker.
I think you mean an apple will ripen bananas or green tomatoes. The apples as they ripen give off gas that aids and speeds up the ripening of other fruits, like placed in a brown bag with bananas or tomatoes and other fruits. Apples stored in the frige crisper drawer will make other fruits ripen quickly, thus go bad before you use them too.
Kalburo is a chemical used to ripen the banana and mango fruits.
As bananas ripen they give off a gas that causes other fruit near them to ripen faster and then spoil.
They give off ethylene gas which will ripen other fruit. Ethylene gas is also used in greenhouse to artificially ripen fruit commercially.
Ethylene is a plant hormone that causes fruits to ripen. Unripened fruits can rot, so if ethylene caused fruit to rot, it should ripen them first. The cause of rotting fruit is most likely due to microorganisms, especially bacteria.
strawberries are NOT like other fruits. They will not continue to ripen once they are picked.
