5b. When a tick sucks in a blood meal that contains Lyme disease bacteria, at first these bacteria live in the tick’s gut where the bacteria get nutrition from the blood meal. When the tick begins its next blood meal, the Lyme disease bacteria move from the tick's gut to its salivary glands. Why is this ability to move to the salivary glands a needed adaptation for Lyme disease bacteria? What would happen to any Lyme disease bacteria that were unable to move from the tick's gut to its salivary glands?

If someone could do the first couple, just so i can see how it's done that would be great! 20 points. complete a dichotomous key for the 10 leaves on the common leaves sheet. the chart provided here allows for 11 pairs of statements. depending on how you build your dichotomous key, you may or may not need all of them, or you may need to add some.

The empty trna moves off and picks up another matching amino acid from the cytoplasm in the cell. the anticodon of the trna, with its attached amino acid, pairs to the codon of the mrna, which is attached to a ribosome. this sequence is repeated until the ribosome reaches a stop codon on the mrna, which signals the end of protein synthesis. the ribosome forms a peptide bond between the amino acids, and an amino acid chain begins to form. when a second trna with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first trna and is bonded to the amino acid of the second trna.

The distant ancestors of tigers may have had bodies without stripes. use the theory of natural selection to explain how tigers may have evolved to have stripes.
