Explain how the terms oxidation and reduction apply even when there is only a partial shift of electrons between atoms linked by
aliina [53]

Explanation:

In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.

Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.

Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.

Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.

Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.

  • Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
  • This leaves a partial negative charge on it.
  • The other electron then becomes partially positively charged.
  • We can then say, the more electronegative specie undergoes reduction.
  • The less electronegative one undergoes oxidation.

The best response is this: USE A MOISTURIZER ON THE SKIN DAILY TO HELP REDUCE ITCHING. 
Using a moisturizer on the skin is an effective mean of reliving dryness and in extension reducing itchiness. The moisturizer will keep the skin moist and thus reduce pruritus.

Cells assemble carbohydrates through dehydration synthesis which means a(n) what molecule is removed when the monomers are bonde
mr_godi [17]
The process for connecting two monomers together is called dehydration synthesis. Dehydration means “removal of water” and synthesis means “to join together”. So in this process, two monomers are covalently bonded by the removal of a water molecule. Each organic monomer has a hydroxyl group on one side and a hydrogen on the other. When two monomers line up side by side, they will have these two functional groups facing one another. The H and the OH will break off of their respective monomers and bond forming a water molecule. This is the dehydration part of the process. Each monomer now has a carbon atom that needs to covalently bond with something, so they bind to each other forming a polymer. That is the synthesis part of the process.

kondaur [170]

Answer:

A mutation may be bad and good depending on the particular environmental conditions

Explanation:

For example, the falciform anemia is a hereditary disease caused by a mutation where the ability to transport oxygen of red blood cells is reduced; however, this genetic disorder is widespread in some African populations because it is a condition that confers resistance to falciparum malaria. In consequence, falciform anemia is a detrimental mutation that may also be beneficial in endemic malaria regions.

Moreover, it is important to note that the higher proportion of non-synonymous substitutions are not subject to selection (only a minor percentage are positively selected) because they are generally localized within non-coding regions, thereby having neutral status.
