dominant alleles |
|
phenotypes |
|
both dominant and recessive alleles |
|

A biological community of interacting organisms and their physical environment is known as:
population |
|
biome |
|
community |
|
ecosystem |
An ecosystem is a biological community of interacting organisms and their physical environment. This includes both the biotic (living) and abiotic (non-living).
In the water cycle, infiltration is most closely related to:
oceans |
|
runoff |
|
rivers |
|
water table |
The water then accumulates as runoff and eventually returns to bodies of water or is absorbed into the Earth (infiltration) and becomes part of the water table, an underground resevoir of fresh water.
During the water cycle, water enters the atmosphere as a gas through which process?
precipitation |
|
evaporation |
|
transpiration |
|
both evaporation and 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.
Which is the proper order of Earth's atmospheric layers from the surface up to space?
stratosphere, troposphere, mesosphere, thermosphere |
|
mesosphere, thermosphere, stratosphere, troposphere |
|
thermosphere, mesosphere, stratosphere, troposphere |
|
troposphere, stratosphere, mesosphere, thermosphere |
The troposphere is the closest layer to Earth, followed by the stratosphere, mesosphere, and finally the thermosphere which borders space.
