Which of the following is the correct order for types of radiation from longest to shortest wavelength?
radio waves → visible light → gamma rays |
|
infrared waves → microwaves → ultraviolet light |
|
microwaves → radio waves → visible light |
|
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.
212°F is how many °C?

The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)

|
dominant alleles |
|
both dominant and recessive alleles |
|
recessive alleles |
A person's genotype is their genetic makeup and includes both dominant and recessive alleles. Phenotype is how the genes express themselves in physical characteristics.
