AB |
|
B |
|
AO |
Blood is categorized into four different types (A, B, AB, and O) based on the type of antigens found on the outside of the red blood cells. Additionally, each type can be negative or positive based on whether or not the cells have an antigen called the Rh factor.
Which of these does not contain oxygenated blood?
pulmonary vein |
|
aorta |
|
left ventricle |
|
right atrium |
To provide oxygen to the body, blood flows through the heart in a path formed by the right atrium → right ventricle → lungs → left atrium → left ventricle → body. When blood enters the right side of the heart it is deoxygenated. It enters the left side of the heart oxygenated after traveling to the lungs.
The transfer of heat by the circulation or movement of the heated parts of a liquid or gas is called:
convection |
|
conduction |
|
radiation |
|
diffusion |
Convection is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. Examples of heat transfer by convection include water coming to a boil on a stove, ice melting, and steam from a cup of coffee.
Water coming to a boil on a stove, ice melting, and steam from a cup of coffee are all examples of which of the following?
reflection |
|
conduction |
|
convection |
|
radiation |
Convection is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.
In the Periodic Table of the Elements, atomic number is equal to which of the following?
number of electrons orbiting the nucleus |
|
number of protons in the nucleus |
|
number of neutrons in the nucleus |
|
number of protons + neutrons in the nucleus |
The Periodic Table of the Elements categorizes elements primarily by the number of protons in their nucleus (atomic number) and secondarily by the characteristics they exhibit.
