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

Neutrons are placed in a magnetic field with magnitude 2.30 t. part a part complete what is the energy difference between the states with the nuclear spin angular momentum components parallel and antiparallel to the field? δe δ e = 2.77×10−7 ev previous answers correct part b part complete which state is lower in energy: the one with its spin component parallel to the field or the one with its spin component antiparallel to the field? which state is lower in energy: the one with its spin component parallel to the field or the one with its spin component antiparallel to the field? parallel antiparallel previous answers correct part c part complete how do your results compare with the energy states for a proton in the same field (δe=4.05×10−7ev)? how do your results compare with the energy states for a proton in the same field this result is smaller than but comparable to that found in the example for protons. this result is greater than but comparable to that found in the example for protons. previous answers correct part d the neutrons can make transitions from one of these states to the other by emitting or absorbing a photon with energy equal to the energy difference of the two states. find the frequency of such a photon. f f = mhz previous answersrequest answer incorrect; try again; 5 attempts remaining
