The solar energy use in Africa These days‚ solar energy has been the most talkative alternative energy source in the world. Unlike the gas‚ oil‚ and coal‚ solar enrgy is one of the clean and renewable resource‚ which can not only generate power but also protect the environment. Africa‚ has second largest population‚ estimated 1.6 billion‚ however‚ around one third of it’s people still live in the condition with no eletricity. (Renewable energy in Africa

This engagement with signs is known as the study of semiotics. Dating back to 460-377BC‚ with the founder of Western medical science‚ Hippocrates

Chapter 37: Water and sugar transport in plants Water moves from areas of high water potential to areas of low water potential. Water’s potential energy in plants is a combination of (1) it’s tendency to move in response to differences in solute concentration and (2) the pressure exerted on it Plants do not expend energy to replace water that is lost to transpiration when stomata are open and photosynthesis is occurring. Instead‚ water moves from soil and roots to leaves long a water potential

Cellular respiration and photosynthesis are fascinating‚ complicated‚ and important processes that are essential to life. Cellular respiration exists in animal and plants‚ whereas photosynthesis only exists in plants due to the chloroplast organelle. Cellular respiration starts with glucose‚ and oxygen and the photosynthesis process on the other hand starts off with the absorption of photons of light from the sun.While the end products of cellular respiration are carbon dioxide‚ water‚ and ATP‚ the
