Task 2You are a zoologist who works for an animal park that features a large pond with turtles of all shapes and sizes. The landscaping department decides to replace the sandy banks around the pond with a decorative rock garden covered in a thick layer of pretty stones and sculptures.-Create a video using Powtoon of the life cycle of turtles.-Record a video of your explanation of it and answer the following questions in your recording:-How would covering the sandy banks of the pond affect the turtles’ life cycle?

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.

explanation:

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
