Ineed a conclusion statemen of why fruit turn brown after being cut and why the process is slowed down when the fruit is covered in acidic?

This because of Oxidation reaction of enzyme polyphenol oxidase presents in fruit cells with Oxygen when exposed to the air.

The oxidation reaction turns fruits brown.

Acidity lowers pH, and therefore affects or inhibits polyphenol oxidase.Therefore it activities slows down because low pH affects the 3D protein structure of enzyme.As a result the brownish effect is slowed down.

Refregeration aslo slows down activities of this enzyme,and therefore browniing

Explanation:

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b

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.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
