Explanation:

The new research carried out by NASA on mars suggets that many of the Mars' ancient channel have been carved by flowing water, were actually formed by melt water beneath glacial ice sheets.

What were your predicted results for glucose transport in the presence of DNP? Briefly state the physiologic basis for your pred
Olegator [25]

Answer:

Prediction results for glucose transport in the presence of Dinitrophenol (DNP) are as following:

  1. Decreased transport of glucose
  2. DNP disrupts the gradient of protons and the output of ATP
  3. ATP needed for the Na+/K+ pump to the est. Gradient Na+
  4. The gradient required for Sodium-glucose cotransporters (SGLTs)

Dinitrophenol (DNP) is an uncoupler, or is capable of separating electron flow and H+ ion pumping for ATP synthesis. This means that ATP synthesis can not use the energy from electron transfer, hence it will support in lab as well.

Innate immunity is the first line of the immune system that comes with birth whereas adaptive or acquired immunity is the immunity that comes throughout life by experiencing or developing the immune system. Adaptive or acquired immunity is the immune response that comes through cell-mediated responses whereas innate immunity is the immune response that includes sweat glands and secretion from the skin. innate immune responses also include digesting and killing bacteria by the saliva, enzymes, lysozymes.

The only characteristic among these that present in both is that they both immune systems found in all vertebrates.

The movement of molecules against the gradient from low concentration to high concentration using ATP
Bogdan [553]

It is also possible to move substances across membranes against their concentration gradient (from areas of low concentration to areas of high concentration). ... If the energy of ATP is directly used to pump molecules against their concentration gradient, the transport is called primary active transport.

Hope this helps
