The observation that chloroplasts and mitochondria each contain their own dna and synthesize some of the proteins that function in these organelles suggests that chloroplasts and mitochondria must divide each time the cell containing them divides are produced by the nucleus of the cell contain three sets of membranes are part of the endomembrane system

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.

ya the other dude is right
