organisms in a community is affected by the biotic factors and abiotic factors. Abiotic factors are the non-living components in the ecosystem such as air‚ water‚ soil‚ temperature and light intensity. Biotic factors are the living components in the ecosystem such as animals and plants. In an ecosystem‚ the living organisms live together in their non-living environment and function as a unit. This dynamic system starts with species‚ populations‚ ecosystems‚ communities and biosphere. A species is

The cell membrane is made up of fats‚ proteins‚ lipids‚ and carbohydrates‚ and is a permeable structure. However‚ this permeation is very discerning because it only lets certain things pass through it. The cell membrane has a layer of phospholipids with hydrophobic ends and hydrophilic tops. The “tails” are made out of phosphate‚ while the “heads” are made up of two strings of fatty acids. There are two layers of these phospholipids‚ called the “bilayer”‚ and the tips of each phospholipid are facing

Ecosystems – Grassland vs. Mountains Every single day‚ we breathe in air and take a look at the green grass‚ we taste the blue water‚ we subconsciously analyze the soil‚ feel grey rocks‚ look down on small insects‚ watch the growing trees‚ the flying birds‚ and even ourselves‚ the people. But all of these elements do not exist just to be there‚ they have a further important meaning interacting with organisms. We are talking about a biological community of interacting organisms and their physical

The kidney is made up of nephrons‚ which are a kidney’s functional units. These nephrons collect fluid filtered from the blood. The kidney connects to the renal artery‚ renal‚ vein‚ and ureter. Purified blood leaves the kidney using the renal vein‚ urine leaves using a ureter and the renal artery carries blood from the aorta to the kidney. The nephron has a cup-shaped nephric capsule that surrounds a cluster of capillaries called the glomerulus. A good deal of fluid from the blood filters into the
