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 level of which hormone increases after ovulation?
MArishka [77]

The answer should be C, progesterone.


Progesterone is the hormone which can help maintain the lining of uterus and to further thicken it so that the uterus is prepared for implantation and the development of a baby. The level of progesterone is significantly rose after ovulation.


On the other hand, LH, luteinising hormone, is produced by oestrogen, another female hormone which will drop after ovulation. LH helps stimulate ovulation and prevent the development of other follicles, the origin of eggs, to form yellow body instead. Which yellow body is the one which stimulates the production of progesterone.


Last but not least, I believe D should be testosterone, and it is a male hormone so it will not be found in female normally.


Therefore, your answer should be C, progesterone.
