volution And Coevolution</h2>
Explanation:
(d) Coevolution results when two or more species influence adaptation in each other.
- <em>Coevolution is the evolution in at least two species in which the evolutionary changes of every specie impact the development of different species. </em>
- As such, exerts selection pressures on, and develops in light of, different species.
- <em>Coevolution - Evolution </em>that outcomes from the <em>connections between animals. </em>
- <em>Convergent evolution</em> Pattern of development in which two inconsequential species bit by bit become like each other through adaptation to a common environment, regularly bringing about closely resembling structures.
Answer:
Glycolysis evolved before Kreb's cycle and Electron Transport chain. This view is supported by following facts:
- Glucose cannot enter the mitochondria and it needs to be broken down into pyruvate in the cytosol by the process of glycolysis.
- Pyruvate then forms acetyl CoA that enters the mitochondria where it undergoes Kreb's cycle.
- The Electron transport Chain occurs by passing of electron and finally donating it to the electron acceptor oxygen. The molecules of NADH produced in the preparatory phase of glycolysis provides the electron for electron transport chain.
- Thus Glycolysis must have evolved before Kreb's Cycle and Electron Transport Chain otherwise the raw materials for both the processes would not have been available.
Answer:
3.)A person shivering when their body temperature is low.
7.)Ants moving within their mounds depending upon the time of day
1-A plant bending toward a light source.
.-Iguanas laying in the sunlight if their body temperature is low.
.-A unicellular organism beating microscopic hairs to escape a chemical pollutant in its environment
.-Birds migrating when seasons change.
The maintenance of relatively constant internal environment of an organism is called Homeostasis.It is an automatic regulations of the body systems and organs controlled by the brain and some receptors, specific for certain body fluctuations.E.g Thermoreceptors Chemoreceptors etc.
The fluctuations in the body internal systems must be controlled within a narrow limits, for existence of living organism.The brain receives inputs from the receptors, and the outputs from the brain ensures the homeostatic control.
The above examples are typical homeostatic responses by the organisms involved, because the inputs from the receptors send signals to the brain ,and the organisms responded to these with the example above.
Explanation:
Allotropes of carbon includes substances such as graphite, diamond or buckminsterfullerene.
They’re all similar in the thing that they’re all made out of carbon only.
However, their structure is different, such as graphite has a layer structure, diamond has a tetrahedral structure, and buckminsterfullerene has a spherical structure.
Since they have different structures, they have different physical properties too. For example, diamond is hard because all the carbon atoms in the structure is held together by strong covalent bonds, while graphite are graphene layers that are held by weak intermolecular forces which makes the layers slide over each other easily thus making graphite soft.
