I'm not sure if this what your looking for but, electrons, neutrons, and protons are the three components that make up an atom.
Electrons are negative
Protons are positive
Neutrons are neutral (or in other words have no charge)
E) be more susceptible to disease and famine
Hope this helps!

The two gasses that make up 99% of the earth's atmosphere are nitrogen and oxygen.
Hope that helped! =)
Protists are eukaryotic organisms that cannot be classified as a plant, animal or fungus. They are mostly unicellular, but others like algae are multicellular. Protists have mitochondria responsible for respiration to produce energy to be used by cells. Additionally, they can be parasites and mostly prefer aquatic or moist environments. They may be classified as animal-like protists (heterotrophs and have ability to move), Plant-like (autotrophs that photosynthesize) and fungi-like (heterotrophs with cells that have cell wall and reproduce by spore forming). Protists reproduce by asexual means (e.g. budding) or sexually. Therefore, in this case we may conclude that they are all parasites and reproduce sexually or asexually.
