Vertebrates:
1) They've got a backbone/spine.
2) Are probably more complex organisms: fish, amphibians, reptiles, birds, mammals (in that order.)
3) Movement is based on an internal skeleton.
4) Wide range of sizes and shapes.
5) K-selected population
Invertebrates:
1) No backbone.
2) Less complex: sponges, worms, mollusks (e.g. snails) , crustaceans (e.i. crabs.) Insects.
3) Movement is not based on an internal skeleton, or some don't move at all.
4) Must be small in size to fulfill their needs for air and nutrients because systems are simpler.
5) R-selected population
Answer:
Epithelia has polarity and is avascular.
Answer:
The interaction that does NOT maintain tertiary structure is a carbon−carbon bond.
Explanation:
The tertiary structure is represented by the superfolding and winding of the secondary structure, constituting very complicated three-dimensional geometric shapes that are maintained by links of: disulfide bond, between the residues of two cysteines; hydrogen bonds, which is formed between the C = O of the carboxylic group and a chain group that has active H; salt bridge, is due to two polar groups of the amino acid chains, which according to the pH will have a positive or negative electrical charge; and hydrophobic interactions, which are interactions between non-polar chains of amino acids within water envelopes.
Carbon-carbon bonds are covalent bonds, which take place between two carbon atoms.
Based on its behavior the ecological term that describes the term is predator
