Answer:
For growing bacteria it is necessary water, a source of carbon and nitrogen, some inorganic salts.
Explanation:
There are plenty of kind of bacteria, even, all of them need water to dissolved their nutrients and to remove the wastes outside of the bacteria body. The source of carbon could be carbon dioxide for some bacteria that do not need a lot of it. In the other hand, there are other bacteria that are feed based on glucose, fructose or another carbohydrate.
Nitrogen sources normally come from air as gaseous element or some inorganic salts like nitrates.
Other bacteria need specific elements like phosphorous, sulfur, zinc, copper, etc.

The ileum has <span>plicae circulares</span>, villi and microvilli, that are folds and projections of the mucosa layer of the ileum, that increase the surface area of food absorption. The mucosa and the submucosa of the stomach have inner folds called rugae that increase the surface areas in which food is digested by enzymes.
Plants have root hairs in their tap roots that also increase the surface area for which they absorb water and nutrient from the soil. Fibrous roots have a mesh-like a network that also increases the surface area for increased absorption.
You need sodium hydroxide, to add to the solution which should "buffer" the pH levels.

Explanation:
Los conductos o vasos linfáticos son tubos que transporta tanto al líquido linfático (linfa) como glóbulos blancos que fluyen a través del sistema linfático. Estos conductos se inician en el intersticio y terminan en conductos de mayor tamaño que desembocan en la base del cuello, entre las venas yugular interna y la subclavia. A medida que va entrando en los tejidos, los conductos linfáticos se van haciendo cada vez más angostos y finos, convirtiéndose finalmente en capilares linfáticos, donde las sustancias que no pueden penetrar los vasos sanguíneos son recogidas por estos capilares.
