Answer:

pollution of land and water

Explanation:

Pesticides, heavy metals hazardous waste and mining for metals or ores all cause land pollution.

These contaminate the land kill the useful microbes present in the soil. Moreover, when used excessively these chemical enter in our food chain and through into our body and cause various disease. Minamata disease in japan is one such example cause be mercury contamination.

These cause water pollution too. Chemical waste in water give rise to eutrophication and leaching.

chubhunter [2.5K]

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

Identical population-splitting events occurred simultaneously on two neighboring islands, Islands B and C, which are each initia
sweet-ann [11.9K]

Answer:

This is due to the event of Speciation that happened for the rodents in Island B but not for the rodents in Island C.

Explanation:

  • Due to splitting of the population,
  • The sub-population of rodents formed in Island B are B1 and B2.
  • The sub-population of rodents formed in Island C are C1 and C2.
  • In case of Island B, each of the B1 and B2 sub-populations that got split from each other developed certain mutations that were necessary for them to adapt to the particular diverse environment each of them were exposed to, through the period of 50,000 years. These mutations were so varied that reproductive isolation was generated between them that resulted in each of them to develop into different species.Hence, speciation happens here and B1 and B2 are incapable of inter-breeding.
  • In case of Island C, each of the C1 and C2 sub-populations that got split might have got exposed to similar environmental change or no environmental change or the environmental change might have been too small to cause drastic change in each of the sub-populations. As a result of this the two sub-populations might have acquired certain mutations to adapt to the environment each of them were exposed to, through a period of 100,000 years. These mutations might not have been too variable or contrasting to cause reproductive isolation between C1 and C2. Hence, no new speciation happens here and C1 and C2 are capable of inter-breeding.
