There are 3 types of polar bears: ones with thick coats, ones with thin coats and ones with medium coats. It is fall, soon to be winter. The temperatures are dropping rapidly and the bears must be kept warm, or they will freeze to death. Many of the bears have had 4 cubs each but due to the extreme cold temperatures, some mothers only have 2 cubs left. What process is this an example of?

Natural Selection.

Explanation:

This process is an example of natural selection. You may know it as "survival of the fittest." This means that the organisms with the best traits for surviving will survive, while the others will unfortunately die off. However, this is good for a species because it means that the future offspring will likely become more and more adapted to their habitats and the world around them!

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
