Answer:
It is because sedimentation will more often occur in marine ecosystems
Explanation:
Formation of fossils (through the process of fossilization) is a rare event because animal bodies are often eaten and decayed (destroyed by scavengers and decomposed by worms). But, fossilization can be achieved after the quick burial of an animal.
So, for example, dead marine animals might be buried by sediment that is carried by the water. Also, sediment can precipitate on the ocean floor, covering the remaining of dead animals.
The aweser would be B properties and rare earth elements
Even the cell membrane is like the cell wall its flexible and lets certain things in and certain things out.
Answer:
A. It decreases the activation energy needed to start the reaction
Explanation:
Organic catalyst which speed up the rate of organic chemical reaction is living cells are called enzymes.They have specific reaction site called active sites.This must be in prefect shape with the substrate for the organic chemical reaction to take place
When this occurs the minimum amount of energy of reaction to activate or stimulate the the atoms and molecules of the substrate to undergo chemical reaction is lowered.This energy of reaction is celled activation energy.
Catalase thought its active sites lowers the activation energy so that the molecules of H2O2 could break down to C02 and H2 faster,thereby reducing the time for theses product to form.The is the general roles of enzyme.To increase the rate of chemical reaction,by reducing the activation energy.
