Which of the following is the correct order for types of radiation from longest to shortest wavelength?
microwaves → radio waves → visible light |
|
visible light → ultraviolet light → radio waves |
|
infrared waves → microwaves → ultraviolet light |
|
radio waves → visible light → gamma rays |
The electromagnetic spectrum covers all possible wavelengths and frequencies of radiation. From lowest frequency (longest wavelength) to highest frequency (shortest wavelength) radiation: radio waves → microwaves → infrared waves → visible light → ultraviolet light → X-rays → gamma rays.
Plant cells are surrounded by:
only a cell membrane |
|
only a cell wall |
|
a cell membrane and a cell wall |
|
neither a cell membrane nor a cell wall |
Animal cells are surrounded by a semipermeable membrane which allows for the transfer of water and oxygen to and from the cell. In plant cells, the cell membrane is surrounded by a somewhat rigid cell wall which provides the cell structure and support.

arthropod |
|
sentient |
|
spiny |
|
vertebrate |
