We impact rivers and streams by fishing because we are taking animals which is part of an enviornment. we also damage it by trash or litter. oil spills and such too can contaminate water for ppl and animals to drink, therefore spreading diseases.

List 3 factors that can speed up the rate of chemical reactions

zysi [14]

Answer:

Temperature
Greater Surface Area
Catalysts

Explanation:

Temperature

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).

Greater Surface Area

The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. ... more particles are exposed to the other reactant. there are more collisions. the rate of reaction increases.

Catalysts

A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism.

The surgical placement of an artificial joint is known as

Alekssandra [29.7K]

Answer:

Arthroplasty

Explanation:

The restoration of function of a joint is called Arthroplasty. The bone functions are restored by maintaining the bones through resurfacing. Some times artificial joints are also used instead of resurfacing the existing bones.

Arthroplasty is a method to cure Osteoarthritis, or degenerative joint disease where joint cartilages reduces with age.

Also when medical treatments no longer make any impact on the joints of bone pain then Arthroplasty is done.
