Answer:
Higher biodiversity seems to be associated with a better response to disturbance events
Explanation:
Biodiversity means 'the variety of life'. Disturbance processes modify the environment and also affect demographic processes such as growth, recruitment, survivorship, etc., thereby producing changes in biodiversity. In an ecosystem, biodiversity contributes to its sustainability. In this regard, it has been shown that disturbance events are less important in species-rich ecosystems such as tropical wet forests compared to less rich ones (such as dry forests). The communities with higher biodiversity levels are known to be more productive in terms of biomass, and thus they seem to be more stable (and successful) to disturbance events.
Plant cells have a cell wall. They also have a larger water vacuole.
Answer: If one is constructing a phylogeny of reptiles using DNA sequence data of birds, mammals, amphibians or fish, the suitable outgroup to be used are mammals due to the time of divergence from other group of organisms.
Explanation: Phylogeny is used to determine evolutionary relationship between items or organisms. A phylogenetic tree is a graphical illustration of phylogenetic relationship. In phylogeny, an outgroup represent an organism that is more distantly related to other group of organisms.
In a phylogenetic tree, outgroup stands alone. It shows that the time of divergence of that particular organism is far from other group of organisms. Outgroup is used to root a tree and sometimes represent a group that is more ancestral on a tree.
It should be noted that differences in the DNA sequences of the organisms under consideration will determine which organism will serve as the outgroup.
