You find a scientist that has been growing the same tomato species in a greenhouse for 30 years. You performed the same experiment described in Question 1 with the greenhouse plants and observed the following phenotypes in the F2 progeny. 155 dwarf, peach, oblate 151 tall, smooth, normal 1 tall, smooth, oblate 1 dwarf, peach, normal 3 dwarf, smooth, normal 4 tall, peach, oblate 37 tall, peach, normal 38 dwarf, smooth, oblate Which phenotypic classes represent double cross over events

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.

Which promotes sustainability? o a. using more landfills o b. finding new sources of coal o c. increasing consumption o d. encouraging recycling programs
