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.

True
Explanation:
Transgenic animals are lines of animals produced by inserting copies of a specific gene or genes into a fertilized egg or early embryo.
The option which identifies the pregnancy complication of most concern in the following scenario is referred to as Infectious bovine rhinotracheitis which causes abortion in unvaccinated animals.
<h3>What is Abortion?</h3>
This is referred to the expulsion of the fetus or embryo before they reach the stage of viability due to various factors such as the presence of some types of virus in some animals.
The animals usually get infected through contaminated food and water given to them during the course of the pregnancy which is why a clean and healthy environment is preferable. The pregnancy complication resulting from this is abortion which is therefore the reason why it was chosen as the most appropriate choice.
