What is the difference between membrane distillation and pervaporation?

1 answer:

8 0

The pervaporation process is a relatively new, having common elements, reverse osmosis and gas permeation . The separating liquid mixtures by pervaporation difference in vapor pressure between the feed and the permeate. This difference in vapor pressure can be obtained in different ways: by vacuum applied to the permeate ,the most used laboratory procedure, or by cooling the permeate vapor, causing a partial vacuum, and most common industrially. The membrane destillation use heat streans to provide the evaporations. The pervaporation uses differente methods. I hope it help.

The correct answer is the arterial blood carbon oxide level.
Arterial blood test measures oxygen and carbon dioxide levels in the blood. It also measures the body's acid-base level, which is normally balanced when an individual is healthy. The normal range for carbon dioxide is 23 to 29 mEq/L.

2,4-dinitrophenol (DNP) is a weak acid that can diffuse across lipid membranes. When added to eukaryotic cells, DNP can enter th

Murljashka [212]

Answer:

a. In the presence of 2,4 dinitrophenol, which is soluble through the lipid membranes, the H+ gets an another route to pass through the membrane. It hampers the proton gradient potential without any generation of ATP. The gradient that was being utilized for the generation of energy is now just lost in the form of heat.

b. With the reduction in the generation of energy, the cells get devoid of ATP, and drive the electron transport chain intensely so that the collapsing proton gradient gets re-established. However, it prevents the ATP synthase by providing a different path to the proton ions and thus diminishing the H+ concentration gradient.

What benefits do plants with a smooth stem have? Does the stem type protect a plant?

gogolik [260]

<h3>Benefits of smooth stem over rough stem:</h3>

Smooth stem plants like guava, eucalyptus etc do have a smooth layer of bark over its stem that comes out as a skin when they shed their barks. Whereas most of the other plants like mango, banyan etc do have a rough corrugated layer of bark over their stem.

The smooth stem doesn’t let water to accumulate in the bark which can led to infections to the tree. It also doesn’t allow any seed to settle on bark that can led to growth of parasites. Thereby this smooth bark saves the trees from some of the probable harm to the tree.

The process of cellular respiration

Salsk061 [2.6K]

Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell. The process occurs in two phases: glycolysis, the breakdown of glucose to pyruvic acid.
