Answer:
a.Most bacteria and fungi are harmless and may be beneficial to other living things.
Explanation:
Bacteria and Fungi are two distinct organisms that belong to different class of organisms. Fungi are eukaryotic while bacteria are prokaryotic. Although they both exist in different life forms such as being parasitic, saprophytic etc. most bacteria and fungi species are harmless and may even be beneficial to other living things.
Bacteria and Fungi are beneficial to other organisms in the sense that they form mutualistic relationships with other living organisms. For example, certain species of bacteria helps to fix nitrogen in the root nodules of leguminous plants, while fungi forms a mutualistic relationship with algae called LICHEN where they benefit one another in a way or the other.
Answer:
Chemical engineering
Explanation: I am not really that good at science but my opinion is that it is chemical engineering because the process of the rock breaking down with the listed factors of water, carbon dioxide etc. If you are not sure you can also look of the definition for each of the engineering factors...
The active site is complementary to its substrate due to its specific 3D structure. The substrate fits in to one specific active site so an enzyme will only bind to one substrate. They are SPECIFIC. Lock and key theory.
Genetic variation or coral spawning
