<span>The answer to this question would be:
</span>degerming<span>
Antisepsis

The act of rubbing alcohol is aimed to kill the bacteria and other microorganisms in the skin. This is hoped can prevent or reduce the risk of infection. Killing the germ can be called as</span> antisepsis. The rubbing also can physically remove the germ, called degerming.

An increase in the permeability of the cells of the collecting tubule to water is due to a(n) ________.
OLga [1]
An increase in the permeability of the cells of the collecting tubule to water is due to an increase in production of ADH. Hormone ADH also called vasopressin is responsible for regulating the amount of water in the blood and is released from the pituitary gland based on signals from the hypothalamus, which detects the water levels of the blood. When too much water is in the blood, the hormone release is decreased and more water is excreted in the kidneys and thus increasing urine output.

Ira is working in a lab with unknown solution.when he inserts the electrical conductivity tester in the unknown,the bulb begins
Mamont248 [21]
Electrical conductivity tester.

If the bulb begins to glow brightly when the plug is submerged in the unknown solution then the solution has high conductivity. 

The bright glow of the bulb resulting from the experiment indicates that the current flows easily through the unknown liquid.

Which of the following sequences is correct for the downhill movement of electrons during cellular respiration? A. glucose – cit
Volgvan

Answer:

B. glucose – NADH – electron transport – O2

Explanation:

This is the sequence  from glycolysis in which  glucose molecules are split down to pyruvate, to oxidative phosphorylation.

During this process the electrons are released from glucose  molecule as it is oxidised multiple times as pyruvate, and other molecules formed subsequently in Kreb's cycle, until the oxidative phosphorylation is reached .

The makes the  carrier molecules to be reduced.Thus NAD→NADH,FAD→FADH .

The electrons from above are  transferred in hydrogen atoms  to matrix by these co-enzymes.Where the H is split to electrons  and protons.

The electrons for the ETC, produce the PMF for transporting  protons into the intramembrane space.

The concentration of protons generated the electrochemical gradients  which is needed to produce energy for for phosphorylation of ADP with Pi to form ATP by ATpase synthase.

The electrons moves as chain,and this is finally accepted by oxygen as the final electron acceptor.

How is the chemical compositon of hydrothermal vents fluid different from surrounding sea water
ICE Princess25 [194]
HEY THERE!!

When seawater seeps down into the ocean crust and is heated by the magma, it undergoes lots of chemical reactions. When the fluid rises up through the seafloor, it carries many new chemicals with it, such as-- copper and zinc.
These chemical reactions also remove chemicals from the seawater, such as oxygen and magnesium.

So clearly vebtus fluid is different from sea water .
