The human cardiovascular system consists of the heart‚ the blood‚ and a system of transporting vessels. A human heart has four chambers: a right and left atrium and a right and left ventricle.

Yes‚ because there is very little rainfall or moisture in the air‚ because most of the water stays frozen. Almost the whole continent is Desert‚ the largest contiguous desert on earth‚ and one of the dryest

Food Deserts There is growing trend of cities across the United States that do not have access to food such as places in Buffalo‚ Baltimore‚ or Detroit. According to the USDA‚ a food desert is to qualify as a “low-access community‚” at least 500 people and/or at least 33 percent of the census tract ’s population must reside more than one mile from a supermarket or large grocery store (for rural census tracts‚ the distance is more than 10 miles). You can even look up a food desert locater

Biosphere Lab Report A biosphere can be defined a lot of different ways. Our interpretation of a biosphere is the area in which life can be contained within. In the case of the earth‚ it means as high as a bird can fly and as deep as fish can swim in the ocean. A biosphere is a closed system that has a constant flow of energy between the organisms living within it and it needs nothing outside of itself but sunlight to continue to be sustained. At the University of Arizona‚ they attempted to build
