Which of these represents the path of blood flow through the heart?
right atrium → left ventricle → lungs → left atrium → right ventricle |
|
left atrium → left ventricle → lungs → right atrium → right ventricle |
|
left atrium → right ventricle → lungs → left atrium → right ventricle |
|
right atrium → right ventricle → lungs → left atrium → left ventricle |
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.
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 |
|
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.

What part of the food chain serves only as food for other organisms?
secondary consumers |
|
primary consumers |
|
producers |
|
decomposers |
Producers (autotrophs) serve as a food source for other organisms. Typical producers are plants that can make their own food through photosynthesis and certain bacteria that are capable of converting inorganic substances into food through chemosynthesis
