<span>A combination of different organisms living within a single area is called an ecosystem. It is also sometimes described as the complex relationship between all the components both living and non-living within a given area. Although there may be a great degree of biodiversity within an ecosystem, all components within an ecosystem depend on each other for one resource or another.A sustainable ecosystem is where there is a healthy balance of all components making up the ecosystem.</span>
Answer:
Evolution is not the same as adaptation or natural selection. Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations
Evolution is a gradual change in the inherited traits of a population over many generations. Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes.
Answer:Medulla and pons.
Explanation: Brain is the part of the body that controls all body activities. Medulla and pins are part of the brain.
Medulla controls respiration. It receives signals from chemoreceptors and send to muscles that allow respiration. It also regulate heart rate and blood pressure to ensure adequate blood supply circulate the body system.
Medulla also help in adjusting respiration when there is need and also generates normal breathing movements by stimulating the nerve that supplies the diaphragm. This pons are located under the medulla and it controls speed of involuntary respiration( respiration
Not under conscious control).
When a patience shows a disorder in respiration, invountary respiration, increase in heart rate its a disorder of Medulla and pons also called Brainstems
