1. What is the flu vaccine and how is it created? 2. Why is each year's vaccine different? Use your research to support your
answer.
3. How does the flu vaccine continue to evolve?
4. How does the flu shot relate to chemistry? Use your research to support
your answer.

Explanation:

is a vaccine in which it can cure the flu it is created by different types of chemicals

each year backs in different because each different type of chemicals come to the different different parts of the country

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
