This in turn produces nutrients for the Stentor. PP actually has a high heat tolerance and as such, does not seem to leach many of the chemicals other plastics do. The exchanged information reorganizes and becomes a new macronuclei. Taking steroids increases testosterone levels, causing effects like increased muscle mass and strength. PP is used to make yogurt containers, deli food containers and winter clothing insulation. The bad news is that these invaders can cause serious diseases. parasite.
