High doses of radiation, chemicals and toxins can result in which is a disorder of pluripotential bone marrow stem cells resulting in a reduction in the number of cells produced and failure to replace senescent red cells.

How are the tortoises that darwin observed on the galápagos islands similar to the anoles that losos studied

During convection, less dense fluid rises and denser fluid sinks.

1. -define adaptation2 explain darwin's theories of descent with modification and natural selection in detail3. -explain how each of these provides evidence for evolution: a. -fossil record, including superposition and transitional fossilsb-anatomy, including homologous structuresc-biological molecules, including dna and proteins4. -explain the difference between convergent and divergent evolution.5. -define and give three examples of artificial selection6. -define and give one example of coevolution.7. -explain biodiversity and how it benefits humans.8. -explain a type of population lest affected by environmental change.
