Answer:
Polar
Explanation:
Polar is a concept which explains the formation of a particular molecule as a result of a separation of electric charges. In such molecule formed, there is a negatively charged end and a positively charged end. The difference in their electronegativity is what determines the strength of the bind formed in the molecule.
Electrically charges object can be used to attract molecules that are polar. This is because, when polar molecules are placed in an electric field, the positive charged end tends to align with the negative plate while the negatively charged end tends to align with the positive end.
Examples of polar molecules are water, hydrogen sulphide, ethanol, and some others.

Answer: Chemical bonding
Explanation: Bonding by sharing electrons is known as covalent bonding and bonding by transferring electrons is known as ionic bonding. Both are a type of chemical bond that bond elements together into molecules.
Answer: Option C) Animal
The cell wall is tough, flexible and fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides cells with structural support and protection. All BUT ONE type of organism has cells with cell walls. That is an animal
Explanation:
One distinguishing feature of animal cells compared to other living cells is the absence of cell wall.
However, the animal cell possess a cell membrane, with which it regulates substances entering or leaving the cell, and also provide protection and mechanical support for the cell against foreign invaders such as pathogens.
