(I don't know if this is right) Being lighter than air relates to density. There are also other noble gas elements with density lighter than air, such as helium. I would fill it with helium and regulate the amount due to the air pressure and altitude wanted/needed. This could be a good response for a middle school course, but if you need an extended response, then provide some scientific terms too.

<h2>False </h2>

Explanation:

The immune system develops integrated innate and adaptive modules that are pathogen type-specific and no single response can effectively control all types of pathogens

Both innate and adaptive immune system operate in cooperative and interdependent ways

Innate immune system is present since birth in an organism and is non specific in nature which means acts against all foreign antigens and molecules and provides first line of defense against pathogens

Adaptive immunity system is the acquired one which is capable of recognizing and selectively eliminating specific foreign antigens and is antigen specific which means can discriminate among different antigens; also has the ability to respond to various kinds of epitopes of pathogens
