Mass spectrometry demonstrated that a bacterial protein and one section of a eukaryotic protein had amino acid sequences that were 90% similar. What else is likely to be true (but would still have to be tested experimentally)? a. The similar sequences are regulated by the same interactions with other amino acids.
b. The similar sequences have very similar quaternary structures.
c. The similar sequences evolved from the eukaryotic protein into a more refined form.
d. The similar sequences share similar functions and shapes.

What organ is the first to receive nutrients that have been absorbed from the digestive tract?

Monarch butterflies have brightly colored orange wings with black patterns on them, making them easily visible to birds that eat butterflies and moths, yet birds rarely eat the monarchs. likewise, the monarch caterpillars are brightly striped yellow and white and black, and they also are rarely eaten by birds, although some wasps will attack them and feed them to their young. what can be inferred from these observations? monarchs must threaten and attack birds, but not wasps. monarchs have a way of discouraging bird predation that does not involve hiding. monarchs’ wings are so colorful that most birds must find them difficult to eat. monarchs lay more eggs than other less conspicuous butterflies.
