PLEASE HELP ME ASAP Why is prerequisite knowledge important to high school students?

It helps you remember what you learned before.
It makes basic knowledge easier to learn.
It prepares you to learn at increasingly complex levels.
It helps you identify the behaviors new assignments require.

Answer B

It makes basic knowledge easier to learn.

Explanation:

Assessing students’ prior knowledge allows an instructor to focus and adapt their teaching plan. For students, it helps them to construct connections between old and new knowledge.

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.  

catya your not at all which answer i've seen you do this on another question!
