Which of the following is the meaning of the chromosome theory of inheritance as expressed in the early twentieth century? a) individuals inherit particular chromosomes attached to genes. b) mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis. c) no more than a single pair of chromosomes can be found in a healthy normal cell. d) natural selection acts on certain chromosome arrays rather than on genes

answer; i do believe that the correct answer is; ///mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis;

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

the fossil record provides evidence of a common ancestor to many species.
