The correct option is D: Sharkskin produces many chemicals that can be collected and used to create antibiotics.
Explanation:
Sharkskin can resist bacteria and other types of germs due to the microscopic pattern of ridges it has on its surface. This is especially useful in case of bacteria that have developed an antibiotic resistance. There are biotechnology companies that are developing a product with a texture like that of a sharkskin, so as to have the same properties of microbial resistance.
Hope that answers the question, have a great day!
Answer: They use enzymes.
Explanation:
Cells employ enzymes to drive and speed up their chemical reactions without being used up themselves. They are the only macromolecular biological catalysts that can start a reaction using the smallest available heat energy, thus overcoming the issue of needing high activation energy. Enzymes work by converting specific substrates to required product by binding them to their active site.
