Answer:
Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele. Recombination also can create a new DNA sequence (a new allele) for a specific gene through intragenic recombination.

explain why norepinephrine requires a protein receptor to exert its effects.
Answer:
I'm going off the top of my head for this one, and this is an educated guess, so check it if you would like to. When the norepinephrine binds to a protein, then the protein relays the info to the cells that are required to do the specific action. This is why we feel a sense of stress, elevated heart rates, or high alertness.

differences between the three classes of platyhelminthes
Answer:
The phylum Platyhelminthes consist of three different classes: Turbellaria, Cestoda and Trematoda. Class turbellaria is composed of many free-living organisms, while some are parasitic. Trematodes are commonly known as flukes. They are parasitic flatworms with an unsegmented body.
Explanation:
The three classes of Platyhelminthes are Turbellaria, Cestoda, and Trematoda.
What are the differences between the three classes of Platyhelminthes?Flatworms are members of the Platyhelminthes phylum. The Turbellaria, popularly known as planarians, the Trematode, usually known as flukes, and the Cestoda, also known as tapeworms, are the three classes that make up the phylum Platyhelminthes. Flatworm species come in more than 25,000 different varieties.
The four classes of Platyhelminthes are Cestoda (tapeworms), which are internal parasites of many vertebrates; Trematoda (internal parasites of humans and other species); and Turbellaria (free-living marine species).
Thus, these are the differences between the three classes of platyhelminthes.
