Which of the following is the correct order for types of radiation from lowest to highest frequency?
infrared waves → microwaves → ultraviolet light |
|
radio waves → visible light → gamma rays |
|
visible light → ultraviolet light → radio waves |
|
microwaves → radio waves → visible light |
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.
Leafy vegetables, beans, potatoes, fruits, and whole grains are good sources of:
saturated fat |
|
fiber |
|

To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(0) + 32\)
\(F° = 0 + 32 = 32\)
Blood is circulated throughout the body via:
arterioles |
|
aorta |
|
capillaries |
|
veins |
The aorta is the body's largest artery and receives blood from the pulmonary vein via the left ventricle. From there, blood is circulated through the rest of the body through smaller arteries called arterioles that branch out from the heart. Finally, blood is delivered to bodily tissues through capillaries.
Which of the following is true about species groups?
a biome is a made up of a group of biospheres |
|
a community is made up of a group of populations |
|
an ecosystem is a biological population |
|
a population is made up of a group of communities |
A population is a group of organisms of the same species who live in the same area at the same time. A community is a group of populations living and interacting with each other in an area.
