Difference Between Plasma and Serum   Plasma minus fibrinogen (blood clotting protein) is called serum.   Like all other languages, high-level speakers have their merits and demerits. Advantages: the presence of abstractions contributes to a more efficient solution of complex problems; languages ​​are designed for intuitive perception, so working with them is quite simple;there are…

Active Transport is Different from Diffusion   In active transport movement of substances and materials take place against the concentration gradient i.e. from lower to higher concentration. While in Diffusion molecules move from higher to lower concentration.   Disadvantages: the implementation of abstractions takes up a lot of resources, which negatively affects performance; changes are…

Short Note on Anaemia   i) This is disease and can be defined as the deficiency of red blood cells in the body.   ii) Its symptoms are yellowing of palate, weakness, dizziness, appearance of dark circles around the eyes, thinning of blood, loss of appetite etc.   iii) It is caused due to deficiency…
