A, B and C are the events that will cause an ecological disturbance.
Rationale:
A. Introduction of a new species: When a new specie is introduced, it increases the competition in ecosystem with the native species for food, water, space and shelter. This affects the reproductive success of the native species and thus the dynamics of ecosystem.
B. Climate change: Climate change is different from a simple change of weather. The best example would be of Antarctica where the ice is melting fast due to the global warming. The native species find it harder to adapt to the warm temperatures.
C. Late spring snowstorm: Spring is the season where the plants grow and animals shed their fur. When snowstorms occur in this season they harm these plants and animals that live there.
chemical formula??! do you mean O2
Small, highly concentrated cell organelles that produce proteins are called <span>ribosomes. Ribosomes can be free-floating or attached to endoplasmic reticulum.</span>
Answer:
Standard taxonomic system is important to the scientific community because it provide several advantages like that organise and classify the organism that organism can be easily categorised it helps to understand the characteristics of a specific organisms, it also benefited to universal recognition that scientific names are standardised and it is accepted universally and it also help to understand the similarities and differences between different species that belonging to the same genera.
(Drawbacks of modern taxonomy) :it is based on physical traits and it is also physically similar and species may not be related and it does not use molecular evidence
