Bulk Transport is an example of active transport. The process by which amoeba engulfs its food and secretes is a type of active transport. Amoeba forms false feet like pseudopodia and engulf food.Active and Passive transport both are related with plasma membrane. Active Transport is the transport of food across plasma membrane with expenditure of energy.

What is the process of making Nak?
While this is a valid question that deserves a valid answer, wiki.answers.com does not allow the formulas of explosive materials to be answered for the safety of the less experienced viewers who may try this without the proper supervision or safety protocols of which it requires.
What is wrong with the chemical formula NaK?
Na is Sodium (Nadium) K is Potassium (Kalium) They both produce positive ions. Na^(+) & K^(+) , and like magnets, where like poles repel and unlike poles attract, the are 'like ions' , Both positive, so they will repel and NOT combine. So the formula NaK doesnot exist .
Why lithium use as heat transfer agent in nuclear reactors?
Its not used in any reactor designs. Most use ordinary water. A few designs use molten metals like sodium, NaK (sodium-potassium alloy), mercury, etc. because they do not slow the neutrons as water would and they want fast neutrons in these designs. These metals also transfer heat more efficiently than water does.
Is sodium used as a salt substitute?
PURE SODIUM will blow your face off. Na+H2O=explosion. Pure sodium is also very soft, and needs to be stabily kept in kerosene. A good substitute for NaCl(sodium chloride, also known as table salt) is NaK-Sodium potassium. The funniest thing about soduim and chlorine is one is a yellow gas that will choke you to death, while the other dropped in water will cause huge explosions. Also, DO NOT TRY TO MAKE YOUR OWN SALT. The reaction could burn you seriously, or an uncontrolled chlorine leak will kill you. The short answer is 'no' -- sodium is a component of salt. What we commonly think of as 'table salt' -- the stuff on french fries that makes them taste, well, salty -- is sodium chloride, or NaCl. When sodium molecules meet chlorine molecules, they form edible salt. The most common 'salt substitute' is potassium chloride, or KCl, which, you might notice, is just like table salt except that it's potassium and chlorine instead of sodium and chlorine.
What are the uses of potassium?
from Encarta: Potassium metal is used in photoelectric cells. Potassium forms many compounds resembling corresponding sodium compounds, based on a valence of 1. A few of the element's most important compounds follow. Potassium bromide (KBr), a white solid formed by the reaction of potassium hydroxide and bromine, is used in photography, engraving, and lithography, and in medicine as a sedative. Potassium chromate (K2CrO4), a yellow crystalline solid, and potassium bichromate, or potassium dichromate (K2Cr2O7), a red crystalline solid, are powerful oxidizing agents used in matches and fireworks, in textile dyeing, and in leather tanning. Potassium iodide (KI), a white crystalline compound that is very soluble in water, is used in photography for preparing gelatin emulsions and in medicine for the treatment of rheumatism and overactivity of the thyroid gland. Potassium nitrate (KNO3), a white solid prepared by fractional crystallization of sodium nitrate and potassium chloride solutions, is used in matches, explosives, and fireworks, and in pickling meat. It occurs naturally as saltpeter. Potassium permanganate (KMnO4), a purple crystalline solid, is used as a disinfectant and germicide and as an oxidizing agent in many important chemical reactions. Potassium sulfate (K2SO4), a white crystalline solid, is an important potassium fertilizer and is also used in the preparation of potassium alum. Potassium hydrogen tartrate (KHC4H4O6), commonly known as cream of tartar, is a white solid used in baking powder and in medicine.
