7. Are there any mammalian cells that would be a good source for dividing cells? What types of cells would most like NOT have cells undergoing division? Please list some examples and be specific on why.

Sorry the first one I don't know.

The second one's answer is :  Mature nerve cells, cardiac muscle cells, skeletal muscle fibers, fat cells, red blood cells, bone cells (osteocytes), and white blood cells (except lymphocytes) do not undergo division

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.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
