temperate front |
|
cold front |
|
warm front |
|
stationary front |

Which of the following is the correct order for types of radiation from lowest to highest frequency?
infrared waves → microwaves → ultraviolet light |
|
microwaves → radio waves → visible light |
|
radio waves → visible light → gamma rays |
|
visible light → ultraviolet light → radio waves |
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.

cells |
|
chromosomes |
During cell division, the cytokinesis phase occurs when cytoplasm and cell membranes complete their separation resulting in two separate cells.
