Answer: Bilateral Symmetry
Explanation:
Echinoderms evolved from bilateral symmetric species.
Even though adult echinoderms have five-sided or pentaradial symmetry, echinoderm larvae are ciliated, free-swimming species that form in bilateral symmetry making them look like embryonic chordats. Example of echinodermata is starfish.
Bilateal symmetry allows them to move anywhere in the water. That when a predator is trapped by 2 arms, the other arms can be used effectively by continuously placing pressure on the body part to pressurerise the animal to open.
Hence, phylum echinodermata have bilateral symmetry.
UAG encodes for a "stop".
Explanation:
A proto-oncogene is a<em> normal gene that usually can stimulate growth and differentiation but if it mutates can become an oncogene and cause cancer</em>. In order to test this gene, you can <em>activate it by promoting its mutation with a DNA amplification (like the one you did in the question) or a chromosomal translocation,</em> then you can observe it in a culture <em>if there's cell transformation you can confirm your hypothesis.</em>

A punnet square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. The diagram is used by biologist to determine the probability of an offspring having particular genotype. Base on that the possible answer would be that the<span> two parents should have genotype a of something like XXi x XY where Xi is the allele for red eye colour</span>
