Capillaries.
<span>Exchange of oxygen and carbon dioxide in the lungs occurs between the capillaries and the alveoli.</span>
Answer:
the leaf disk should float because bicarbonate is the source of its oxygen for photosynthesis and it releases oxygen into the interior of the disk causing it to float.
Explanation:
Chemical equilibrium, because all reaction speed in an equilibrium would shift towards the side with the least concentration of molecules.
Answer:
Molecules that are not soluble in water are fats and non-polar molecules . During their digestion and absorption in the small snall intestine, fats are packaged into hydrophilic form.
Explanation:
This explains the digestion of fats in the small intestine. This takes place in the illeum.( the longest part of 3.5 m) Bile salts from the liver, emulsified these fats, covering then with layers,while enzymatic action by lipase, from the pancreases, completes the process.
These fatty substance formed are called Micelles.In the intestinal cells, the micelles are covered by protein and lipids to aid transport in water medium of the intestine.A this sage they are called (lipoprotein).
They are absorbed in the lacteal- the lymphatic capillaries , unlike protein and CHO which are absorbed directly in the blood stream.I
They are finally absorbed into the blood stream via the lymphatic vessels.
