Put the steps of translation in order: a. an exposed codon attracts a complementary tRNA bearing an amino acid
b. the ribosome pulls the mRNA strand the length of one codon. The first tRNA exits the ribosome, and another codon is exposed
c. the ribosome assembles at the start codon of an mRNA strand
d. when the ribosome encounters a stop codon, it falls apart and the protein is released
e. the ribosome forms a peptide bond between the amino acids. It breaks the bond between the first amino acid and tRNA

If you relate the doppler effect on sound to the color of light waves, a police car would be the color as it approaches and the color as it recedes away from the observer.

9. technology can bring both good and bad things. building a vertical farm can increase food supplies in cities (good), but it may cause unemployment in rural areas (bad). give another example of both the good and bad sides of a technological advancement (5 noints)

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.
