Provide structure and support, facilitate growth through mitosis. allow passive and active transport, produce energy, create metabolic reactions, aids in reproductive.
Answer:
The correct answer is A) Conformation.
Explanation:
Proton pumps are usually molecules that are able to change its conformation in order to transport molecules from one side to the other. The amino acid sequence cannot be changed, because it would change completely the function of the protein. For example, the sodium/potassium pump changes its conformation in order to move these molecules from one side of the membrane to the other.

Three excision repair pathways exist to repair single stranded DNA damage: Nucleotide excision repair (NER), base excision repair (BER), and DNA mismatch repair (MMR).</span>
Flatworms-In the life cycle of trematode flukes of the subclass Digenea, mollusks (mostly snails) serve as the intermediate host. Fertilized eggs usually hatch in water. The first larval stage, the miracidium, generally is free-swimming and penetrates a freshwater or marine snail, unless it has already been ingested by one.
Roundworms-Roundworms can complete their life cycle in immature dogs, but as the pup's immune system matures (usually by 6 months of age), the larval stages of the roundworm will become arrested and will encyst (become enclosed in a cyst) in the pup's muscles. They can remain encysted in the dog's tissues for months or years.
