Which of the following is the correct order for types of radiation from longest to shortest wavelength?
infrared waves → microwaves → ultraviolet light |
|
radio waves → visible light → gamma rays |
|
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.
Someone who has Rh-factor __________ blood cannot receive blood with a __________ type.
positive, antigen |
|
antigen, negative |
|
positive, negative |
|
negative, positive |
Blood transfer is limited by the type and Rh factor of the blood. Someone who has Rh-factor negative blood cannot receive blood with a positive type but a person with Rh-factor positive type blood can receive Rh-negative blood. Type O negative blood is the universal donor because it can be given to a person with any blood type. Type AB positive is the universal recipient meaning someone with this blood type can receive any other type of blood.

Cellular fermentation takes place:
in plant cells |
|
anaerobically |
|
in the presence of oxygen |
|
aerobically |
If no oxygen is present, cellular respiration is anaerobic and will result in fermentation where either lactic acid or alcohol is used instead of oxygen.
In the heart, the __________ artery and vein manage blood flow to the lungs.
atrial |
|
aorta |
|
pulmonary |
|
capillary |
The two largest veins in the body, the venae cavae, pass blood to the right ventricle which pumps the blood to the lungs through the pulmonary artery. Blood picks up oxygen in the lungs and returns it to the left atrium via the pulmonary vein.
