Answer:

Transplant with a healthy intestine.

Explanation:

The only way Sammy has recovered from this intestinal infection with the help of transplant with a healthy intestine because lower intestine is very important part of the human body because it absorb nutrients present in the food and transported these nutrients in the blood vessel present in it. These nutrients then used by the human body in different functions and activities. So it is concluded that transplant is the only way to cure from intestinal disorder.

A) Compare and contrast diffusion, passive transport (diffusion & facilitated), primary active transport and secondary activ

zheka24 [161]

Answer:

Passive transport: It does not need any energy to occur. Happens in favor of an electrochemical gradient. Simple diffusion and facilitated diffusion are kinds of passive transport.

Simple diffusion: molecules freely moves through the membrane.

Facilitated diffusion: molecules are carried through the membrane by channel proteins or carrier proteins.

Active transport needs energy, which can be taken from the ATP molecule (Primary active transport) or from a membrane electrical potential (Secondary active transport).

Explanation:

Diffusion: This is a pathway for some small polar hydrophilic molecules that can freely move through the membrane. Membrane´s permeability depends on the size of the molecule, the bigger the molecule is, the less capacity to cross the membrane it has. Diffusion is a very slow process and to be efficient requires short distances and pronounced concentration gradients. An example of diffusion is osmosis where water is the transported molecule.

Facilitated diffusion: Refers to the transport of hydrophilic molecules that are not able to freely cross the membrane. Channel protein and many carrier proteins are in charge of this passive transport. If uncharged molecules need to be carried this process depends on concentration gradients and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an electrochemical gradient. The glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.

Simple diffusion and facilitated diffusion are passive transport processes because the cell does not need any energy to make it happen.

Active transport occurs against the electrochemical gradient, so it does need energy to happen. Molecules go from a high concentration side to a lower concentration side. This process is always in charge of carrier proteins. In primary active transport the energy needed comes from the ATP molecule. An example of primary active transport is the Na-K bomb. In secondary active transport, the energy comes from the membrane electric potential. Examples of secondary active transport are the carriage of Na, K, Mg metallic ions.

Additional compounds can be added to agar before sterilization (or sometimes after). an example of this is "milk agar," in which

Marat540 [252]

The lactose-digesting bacteria like to grow on milk agar .Bacillus cereus growth and survival were examined during the production of cheese of the Gouda variety. Approximately 102 B. cereus spores per milliliter of cheese milk were intentionally added to pasteurized milk before it was used to make the cheese in the pilot plant.

"milk agar," in which 2% nonfat powdered milk is added to the agar base. lactose-digesting bacteria like to grow on milk agar. Surface plating on B. cereus selective medium was used to count B. cereus, while lactic acid bacteria were counted on lactic agar and MRS agar (de Man-Rogosa-Sharpe). Samples of the milk before renneting, the curd at cutting, the half-whey removal, the final whey removal, the hooping of the curd, the cheese after pressing, the cheese after brining, after one week, after two weeks, after four weeks, and after six weeks were all taken for microbiological analysis. The growth of lactic acid bacteria during cheese production was unaffected by B. cereus.
