Review the data table comparing the five phyla. Scientists sometimes draw a cladogram grouping the echinodermata
and hemichordate as sister groups. Elaborate on why this is appropriate
A
Both are deuterosomes.
B)
The larval forms of both phyla are identical in structure.
The hemichordata do not possess the four characteristics of chordata.
D
The echinodermata and hemichordate share more characteristics than any
other two phyla in the chart.

Explain the side effects of cancer treatments

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.
