TASK 3 COMPONENTS OF BLOOD AND TRANSPORT OF OXYGEN Blood components are red cells‚ white cells‚ platelets and plasma. These can be put to different uses. RED BLOOD CELLS Red blood cell also known as erythrocytes make up 45% of blood volume lacks nucleus and contains the oxygen-carrying protein haemoglobin‚ which is a pigment that gives whole blood its red colour. Erythrocytes are produced inside of red bone marrow. Its main function is to distribute oxygen to body tissue‚ and carry waste

and resources‚ all populations must eventually have decreasing grovtrth rates. Logistic growth models allow for exponential growth when the population is small. However‚ as the population approaches a critical size called the carrying capacity‚ the growth rate approaches zero. The result is a self-regulating population. - Logistic Growth We letp(r) be the population of a community or species at time t > 0‚ which means thatp’(r) is the population growth rate.

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
