Which of the following is the correct order for types of radiation from longest to shortest wavelength?
microwaves → radio waves → visible light |
|
radio waves → visible light → gamma rays |
|
visible light → ultraviolet light → radio waves |
|
infrared waves → microwaves → ultraviolet 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.
Which of the following members of the food chain are most alike?
scavengers and decomposers |
|
producers and tertiary consumers |
|
herbivores and autotrophs |
|
primary consumers and omnivores |
Like decomposers, scavengers also break down the dead bodies of plants and animals into simple nutrients. The difference is that scavengers operate on much larger refuse and dead animals (carrion). Decomposers then consume the much smaller particles left over by the scavengers.
Elements that belong to the same period in the Periodic Table of the Elements have the same number of:
electrons |
|
atomic mass units |
|
protons |
|
electron shells |
The rows of the Periodic Table are called periods and contain elements that have the same number of electron shells ordered from lower to higher atomic number.
What part of the brain is responsible for the major senses (thinking, hearing, seeing)?
brainstem |
|
medulla |
|
cerebrum |
|
cerebellum |
The cerebrum is the major part of the brain and is responsible for the main senses (thinking, hearing, seeing).
Which of the following is not a method of heat transfer?
convection |
|
conduction |
|
radiation |
|
reflection |
Heat is always transferred from warmer to cooler environments through conduction, convection, or radiation.
