Answer:
- Two predictors to measure biodiversity: Species Richness and Simpson's Index
- Biodiversity increases ecosystem stability
- It has been shown that natural ecosystems are more stable than monocultures, while isolated human populations are found in highly diverse ecosystems
Explanation:
Two major predictors to measure biodiversity are: 1-species richness and the 2-Simpson's index. The species richness is a count for the total number of the species in a given habitat and/or ecosystem; while Simpson's index is a similarity index that indicates the likelihood that two different individuals selected at random from a sample will belong to the same species, thereby also estimating the biodiversity of a habit and/or ecosystem. Simpson's index takes into consideration the number of species and the abundance of each species. Ecosystems with high diversity tend to be more stable and resilient than ecosystems with low diversity. Biodiversity increases ecosystem stability due to the species asynchrony, which is a strong driver capable of stabilizing multiple processes/functions in the ecosystems over time (e.g., the productivity of the ecosystems over time). In this regard, it has been shown that forests that are highly diverse in the number of species are more productive and stable under stress than monocultures (i.e., agricultural crops), while isolated human populations live in sustainable ecosystems, it is for that reasons that isolated tribes are only found in highly diverse ecosystems.
Answer:
Bed D is the oldest
Explanation:
Hope this helps also the bed that are on the lowest portion is always the oldest layer.
Answer: Kira has difficulty in walking in smooth coordinated manner because she has suffered injury to the cerebellum.
Explanation:
Cerebellum is a part of the brain situated inferior to cerbrum and posterior to pons. It receives sensory information and converts it into motor responses. Motor coordination is when subsequent parts of the same movement, or the movements of several limbs or body parts are combined in a manner that is well timed, smooth, and efficient. Cerebellum coordinates voluntary motor movements resulting in smooth coordinated muscular activities. Injury to cerebellum causes its loss of function which in return causes
1) loss of coordinated movements
2) inability to perform alternate rapid movements
3) movement tremors
4) staggering wide based gait
Recrystallization. During the process of metamorphism, the particle size of the rock may change by a process called recrystallization. For instance, the small calcite crystals in limestone, a sedimentary rock, change into larger crystals during formation of the metamorphic rock marble.
