News The lymphatic system is part of the immune system. It also maintains fluid balance and plays a role in absorbing fats and fat-soluble nutrients. The lymphatic or lymph system involves an extensive network of vessels that passes through almost all our tissues to allow for the movement of a fluid called lymph. Lymph circulates through the body in a similar way to blood.
Account for the differences in oxygen consumption observed between: Explain why each of these features is necessary. State the conclusions reached by Mendel in his work on the inheritance of characteristics. Explain how each of the following deviates from these conclusions.
Experiments by the following scientists provided critical information concerning DNA. Describe each classical experiment and indicate how it provided evidence for the chemical nature of the gene. Explain how the events of meiosis I account for the observations that led Mendel to formulate these laws.
An organism is heterozygous at two genetic loci on different chromosomes. Explain how these alleles are transmitted by the process of mitosis to daughter cells.
