False. Think about how teachers have air conditioners on the top of the windows and how air balloons float up!! Therefore warm hair is lighter then cold air.
It is a lipid. Lipids are some of the most complex basic materials in biology. You can remember them as they have 23 hydrogens, and one H0.
Answer:
D overlap for a variety of species.
Explanation:
During ecological succession, a sequence of changes occurs in a community at a temporal and spatial level. Local colonizations and extinctions occur while ecosystems evolve at a more complex level.
Ecological succession occurs in <u>stages</u>. The first stages are represented by communities of simple trophic levels and few species. With time, as the communities go through different stages, they transform into more complex ecosystems, that are much richer in diversity, and showing more interaction among the different species that compose it. The final stage is known as the climax and represents a mature and stable system.
While the community is going through these changes, many species get extinct while many others get to emerge and survive. It occurs overlapping of different taxonomic groups that interact with each other competing or beneficiating other groups.
The reasons are many. The most major reason was the fact that they were outnumbered by the U.S.
