When compared to eukaryotic cells, prokaryotic cells are:
less complex |
|
similarly complex |
|
none of these |
|
more complex |
Cells are classified into one of two groups based on whether or not they have a nucleus. Eukaryotic cells have a nucleus, prokaryotic cells do not have a nucleus and therefore have a less complex structure than eukaryotic cells.
During the water cycle, water enters the atmosphere as a gas through which process?
evaporation |
|
both evaporation and transpiration |
|
precipitation |
|
transpiration |
The water (hydrologic) cycle describes the movement of water from Earth through the atmosphere and back to Earth. The cycle starts when water evaporates into a gas from bodies of water like rivers, lakes and oceans or transpirates from the leaves of plants.
The heat from the Sun traveling to Earth is an example of which of the following?
conduction |
|
electricity |
|
radiation |
|
convection |
Radiation occurs when electromagnetic waves transmit heat. An example is the heat from the Sun as it travels to Earth.
Secondary consumers that also eat producers are known as:
carnivores |
|
scavengers |
|
omnivores |
|
herbivores |
Secondary consumers (carnivores) subsist mainly on primary consumers. Omnivores are secondary consumers that also eat producers. Examples are rats, fish, and chickens.
Which of the following is the correct order for types of radiation from lowest to highest frequency?
radio waves → visible light → gamma rays |
|
infrared waves → microwaves → ultraviolet light |
|
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.
