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

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.

Explain what happens to animal cells if they are put in fresh water
neonofarm [45]
They will actually explode or burst

So What happens is the pure water outside has a high water potential while the cytoplasm inside the animal cell is a low water potential, water will diffuse down a water potential gradient through the semi-permeable membrane of the animal cell and cause the cell to swell (inflate like a fully-blown balloon), the result is that the delicate, elastic cell membrane<span> can't tolerate the internal pressure coming from the cytoplasm so it tears causing the cell to burst.</span><span>

Which adaptation is the likely result of convergent evolution?
bezimeni [28]

A result of convergent evolution are the webbed feet of ducks and frogs.

Explanation:

The evolution of the animals, or rather the development of adaptive features, works in very interesting manner. It is very common in nature that animals that are closely related do not share similar characteristics, or the opposite, animals that are not closely related but share similar characteristics. The later case, is referred to as convergent evolution, where totally different animals have developed the same or very similar characteristics in order to be better suited for their environment.

In this case we have the ducks and frogs, and the webbed feet as shared adaptations, or feature. The ducks are birds, while the frogs are amphibians, and their last common ancestor has lived hundreds of millions of years ago. Despite that, both animals have developed webbed feet, and the reason for this has been that both animals have faced the same challenge, swimming and diving, and the webbed feet help them to be much faster and more agile in the water.

Other examples of convergent evolution (in the present and in the past) are:

  • Hyena - Tasmanian devil
  • Sandy cat - Fenec fox
  • Smilodon - Thylacosmilus
  • Bats - Birds

Maurinko [17]

The correct answer is: A. A watery mixture of partially digested food released by the stomach into the intestines

Chyme or chymus is formed in the stomach, during the process of digestion (it takes 40 minutes to 3 hours to be produced) , and it is transported to the small intestine-duodenum.

In the beginning of the digestion (in the mouth), mixture of food and saliva called bolus, is formed. Mechanical and chemical breakdown of a bolus creates chime which is ready for the extraction of nutrients from it.
