Question

cladograms

1. the more amino acids an organism has in common, both in type and order, the closer the relationship between organisms. the same is true for nucleotides (the code for dna). compare the biochemical data above. which organism is most closely related to the lizard? a dolphin
2. why did you choose that organism?

because a dolphin and lizard have the same dna sequence.

1. which organism is most closely related to the dolphin?

a lizard

1. why did you choose that organism?

dolphins and lizards share the same dna sequence

1. how do you think different amino acid sequences would affect organisms? the dolphin and

Explanation:

Question 3

The problem is about determining the organism most closely related to the dolphin. From the context (like in question 1 where the relationship is based on shared DNA/amino acid sequences), and the given option A is lizard. Also, question 4's explanation mentions dolphins and lizards share the same DNA sequence, which supports that the lizard is most closely related to the dolphin.

Amino acid sequences determine the structure and function of proteins. Different amino acid sequences can lead to different protein structures (like primary, secondary, tertiary, quaternary structures). This can affect the protein's function, such as enzyme activity, structural support, or signaling. For organisms, this can lead to differences in traits, physiology, and potentially survival and reproduction. For example, a change in an enzyme's amino acid sequence might make it less efficient, affecting metabolic processes.

Answer:

A. lizard
