An essay about cycles in biology. Jessie Dean Biological cycles are vital in many aspects of life on earth. From cycles within the body that keep organisms alive such as the cell cycle‚ Krebs cycle and the Calvin cycle to cycles that encompass many aspects of life and our planet such as the Nitrogen and Carbon cycles. The cell cycle involves actively dividing eukaryotic cells passing through a series of stages known collectively as the cell cycle. The two gap phases (G1 and G2) and S (for synthesis)

Transport System of Organisms Problems faced by Multicellular Organisms: a)Big size-the total surface area to volume (TSA/V) is decreased . Rate of diffusion of substances into and out of all body cells is low. b)Cells are often located far away from the external surface of the body. How multicellular organism overcome these problem? a)Have specialized structure to increase the surface area for the exchange of respiration gases. b)Have transport system to get gases respiration in and

vehicle be designed that does not utilize a direct chain and sprocket system. Replacing this power train with a hydraulic one presents various problems. These include reduced efficiency‚ pedal and pump rotational speed discrepancies‚ and increased overall weight. In order to offset the drawbacks of efficiency loss‚ the team added value to the design by creatively using hydraulic components in various configurations.

growth were speed was considered high priority and was evidence of stronger economy. The belief was that Supersonic aircraft would replace all other aircraft what would eventually become known as a supersonic transport (SST). In aviation‚ high-speed and altitude where the most desired progress where faster and higher was better. Research and design studies into supersonic flight at the Royal Aircraft Establishment (RAE)‚ and comparable projects in France undertook fundamental examination since mid

Sulfur Cycle Sulfur (S)‚ the tenth most abundant element in the universe‚ is a brittle‚ yellow‚ tasteless‚ and odorless non-metallic element. It comprises many vitamins‚ proteins‚ and hormones that play critical roles in both climate and in the health of various ecosystems. The majority of the Earth’s sulfur is stored underground in rocks and minerals‚ including as sulfate salts buried deep within ocean sediments. The sulfur cycle contains both atmospheric and terrestrial processes. Within the
