Answer:
The two species concepts that are most likely to place dogs and wolves together into a single species are <u><em>biological and phylogenetic</em></u> concepts.
Explanation:
- The biological species concept establishes that a species is a group in a population whose individuals can mate and have viable, fertile descendence. These groups are also reproductively isolated from other groups or species. This is, the members of a species can not reproduce with the members of other species, or they can their progeny is unviable.
- The phylogenetic species concept refers to a species as the monophyletic group that is less inclusive for organisms. It is a group of organisms that share an ancestor in common and can distinguish from other similar groups. In this concept, a unique species can include a wide phenotypic variability.
Answer:
to break down food into nutrients
Water erosion is usually what people think of, but ice, wind and gravity can also cause erosion.
Water erosion is usually along rivers. As the water moves quickly by it rubs on the rock and dirt, causing rivers to slowly get wider.
Ice erosion is caused by glaciers. Sometimes it's a glacier rubbing against land, and there's a lake that was made by a glacier making it's way onto land and then melting.
Wind erosion is a big problem in fields and large open plains with loose dirt. The wind just blows all the dirt away.
Gravity can cause erosion and cliffs. Sometimes along a mountain or cliff the rock won't be able to hold itself up anymore, and gravity will pull it down.
Your answer would be all of them. Wind, water, ice, and gravity.
The root of the plant is what takes in water.
