The meaning of blood pressure

The meaning of blood pressure SUMMARY: This article talks about all the physical aspects of blood pressure. The first few sections talks about the 3 forces that affect blood pressure: elastic, kinetic, and gravitational. The author also talks about how kinetic energy can be converted to elastic energy in the case of an aneurysm in… Continue reading The meaning of blood pressure

Powered by Light: phototrophy and photosynthesis in prokaryotes and its evolution SUMMARY: This article looks at the still-not-yet-fully-known evolution and history of photosynthesis. There were various types of photosynthesis, the main difference being the type of electron donor. Some organisms used water as an electron donor, while others used things like hydrogen and manganese. The… Continue reading Powered by Light
