Answer:
Whether matter exists as a solid, liquid or gas is determined by the arrangement of its particles and the strength of attraction between the particles. The three states can be easily distinguished because of their physical properties.
A physical property is a characteristic of matter which can be observed without any chemical change to the matter (shape, volume, colour, smell etc.). A chemical change is one in which new substance are formed.
Explanation:
Solids have <u>a fixed volume and shape</u>. They also vibrate in a fixed position. Ice
Liquids have <u>do not have a fixed shape but a definite volume</u>. They take the shape of their container. They are able to move past each other by allowing the liquid to flow. Water
Gases <u>do not have a fixed shape or volume</u>. Particles take up the space of the container they are in. Particles move freely and rapidly. Water vapour

Answer: Botulinum toxin
Toxins are non-living
biological and chemical agents produced by living microorganisms from animals
and plants that can cause harm to humans, plants and animals. An example of
toxin is botulinum toxin produced by the bacterium Clostridium, which is a
neurotoxic protein that prevents the release of the neurotransmitter
acetylcholine from axon endings at the neuromuscular junction and causes
flaccid paralysis.
Moreover, toxin are more
closely related to chemical warfare agents that can only affect those who are
exposed to the agent and that they are not considered as transmissible disease.
