The hardest question in the world about computer technology is an entire class of questions - and that class doesn't have a definite answer. Yet. Is P = NP? We don't know. http://en.wikipedia.org/wiki/P_versus_NP_problem

Actually there is nothing hardest in the world. It depends on how u take it.But i have some questions for u

Biology question-(1) Which component of plasma decreases the water potential of blood by the greatest amount?

(2) A parasite which lives in tissue fluid can block lymph capillaries, cuasing swelling of the tissues, particularly in the leg. Explain why blockage of the lymph capillaries leads to swelling in the tissues.

(3) Explain how the lymph system is involved in the absorption of the products of digestion.

ANSWERS

1. Water potential is influenced by many factors. For the plasma specifically, the lower the solute potential, the lower the water potential.

2. The lymphatic system is used to carry lymph and white blood cells around the body. If it is blocked by a parasite, the lymph cannot be transported and will accumulate, leading to swelling. Also, white blood cells would rush to the blockage site to attach the parasite. This will cause inflammation and swollen lymph node.

3. Besides carrying lymph and white blood cells, the lymphatic system is also used to carry fats that have been absorbed through the intestine. There are more to this but generally speaking, the lymphatic system transport fats.
