The following diagram shows the branching tree diagram for some animals. a slanting line is shown. there are five lines drawn vertically on this line at equal intervals. shark, frog, kangaroo, lion and chimpanzee are written on top of each vertical line in order from left to right. common ancestor is written on the left end of the line. there is a black circle between each pair of these vertical lines. the first black circle is before shark and says vertebrae. the second black circle is between shark and frog and says lungs. the third black circle is between frog and kangaroo and says mammary gland. the fourth black circle is between kangaroo and lion and says placenta. the fifth black circle is between lion and chimpanzee and says large brain. which two organisms share the least number of derived characteristics? frog and kangaroo kangaroo and chimpanzee lion and chimpanzee shark and chimpanzee

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c. what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
