1. Insects don't have lungs. They get oxygen from small tubes in their bodies that are connected to the outside air. Oxygen
diffuses through the tubes to reach their cells. Does this

telophase and anaphase

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
