Answer:
amoeba made up one of the only cells.
Explanation:
Radio waves, like all__electromagnetic _____ radiation are fundamentally different than _mechanical_______ waves such as sound. Even though
they share many similar properties, sound waves require a_medium____,while__radio____waves do not. Sound is the___vibrations___ of molecules and caused by pressure waves. There are no molecules in a __vacuum___
So, sound cannot travel through a vacuum or outer space. Radio waves are electromagnetic waves. They are the vibrations of _electric____ and_Magnetic_______
fields and require no matter to vibrate through. So, radio waves__can___
travel through outer space or a vacuum.
Mechanical waves are simply waves that causes oscillation of a body to transfer energy through it.
Sound and electromagnetic waves are both mechanical waves. Sound is propagated as a longitudinal wave parallel to the source.
Electromagnetic waves are transverse waves that are propagated perpendicularly away from their source.
Sound cannot be propagated in a vacuum but electromagnetic waves are. They do not require a materials medium to be transported through.

Capsid is the component of a virus that is lacking in its cell
A capsid is the protein shell that surrounds a virus. Capsids functions by protecting the nucleic acids of a virus while interacting with the host environment. Capsids are made up of many oligomeric structural subunits that contains the protein; protomers. Capsids are generally grouped based on their structure. The common ones are helical and icosahedral.
Answer:
There must be an independent variable, which changes throughout the course of an experiment; a dependent variable, which is observed and measured; and a controlled variable, also known as the "constant" variable, which must remain consistent and unchanging throughout the experiment.
