B- Enzymes act as catalysts to speed up chemical reactions
Answer:
Genome
Explanation:
A genome of an animal is the complete set of DNA that it holds. Thus, it is quite important for scientists to map species' genomes for study and preservation.
Answer:
At low temperatures enzyme activity is low because the enzyme and substrate molecules have less kinetic energy so there are fewer collisions between them.
Explanation:
At the outer edges of ocean crust
Explanation:
The rocks found in continents are older and in some cases the oldest. The younger rocks are found in mid ridge of ocean. The oldest rocks can be found in ocean trenches that are very deep.
At the outer edges of ocean crust, oldest rocks can’t be found as relatively newer ones are formed continually and mostly found. So, different regions have different ages of rocks and needs to be explored properly.
