Answer:
Lobe-finned fish are thought to be the close relatives to tetrapods because of the fact that the fins are very flexible and potentially useful for supporting the body on land, as in lungfish and tetrapods.
Explanation:
When an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process.
In the gene pool of population with 350 individuals a fixed allele has a frequency of 1(one). Fixed alleles is the alleles that is the only variant that exist for that gene in all population.The frequency of gene pool with a population of 350 is = 1 since the frequency of total alleles =1
Answer:
Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy. Like all catalysts, enzymes take part in the reaction - that is how they provide an alternative reaction pathway.

I think benthos they are like shells
