Answer:
Tissue fluid consists of water, ions, and dissolved gases and food substances, which is formed when blood is ultrafiltered from the capillaries into the intercellular spaces. The tissue fluid surrounds the body cells, facilitating the exchange of nutrients and waste materials. It helps bring oxygen and nutrients to cells and to remove waste products from them. As new tissue fluid is made, it replaces older fluid, which drains towards lymph vessels.
Lymph is a colorless fluid containing white blood cells, which bathes the tissues and drains through the lymphatic system into the bloodstream. It is essentially tissue fluid that has entered a lymphatic capillary. Lymph formation depends upon tissue fluid formation.

Explanation:
behaviors of people as well as the rapid advances of technology, amounts and the composition of MSW have been also changed. In a study carried out by the European Environmental Agency to study the per capita annual MSW produced by 32 European countries during 2001–2010, they found that this waste increased in 21 countries, and was decreased in 11 countries. The study also studied the amount of wastes of 26 countries between 2001 and 2008; they found that these amounts decreased in 6 countries. Thus, the amounts and characteristics of the wastes varied from country to another country, as well as from region to region even within the same city according the mentioned factors including the usage habits of people
Answer: Divide each weight expressed
Explanation: If your first test is 20 percent of your grade, divide 20 by 100 to get 0.2. If your second test is worth 30 percent and your final test is worth 50 percent, divide 30 and 50 by 100 to get 0.3 and 0.5.
Answer:
The answer is that It's true.
When you lift a box up off the floor, you must exert a force at least equal to the weight of the box. If you lift the box at constant speed, you "do work" on the box that would be equal to the force you exert (the weight of the box) times the height through which you lifted the box. If you exert a force of 50 Newtons on the box and lift it 1 meter high, then you did (50 N)x(1 m) or 50 N-m of work on the object. 1 Newton-meter is called a Joule (J), pronounced "jewel." In lifting the 50 N box upward 1 meter at constant speed, you would do 50 Joules of work on the box. That means your body used 50 J of energy to lift the box.
Equation for Work: Work = Force x distance, or W = F d.
Units for Work: N-m (Newton times meter, pronounced "Newton meter") or the Joule (J).
What does work produce? When work is done on an object, the energy of the object changes. In the example above, the amount of energy used to lift the box is stored as gravitational potential energy in the box (see below). If you push a car that has run out of gas, the work you would do in pushing the car would be converted into the energy of motion known as kinetic energy. Therefore, we conclude that work produces a change in energy (either potential or kinetic or both).
