How does non-human life in an urban ecosystem differ from non-human life in an undeveloped forest ecosystem? (Site 1)
ahrayia [7]

Answer:

- Urban ecosystem: highly disturbed systems. Air, water and soil pollution by various pollutants.  

- Undeveloped forest ecosystem: non disturbed systems. Low or null levels of pollution.

Explanation:

An urban ecosystem can be defined as the community of plants, animals, and humans inhabiting an urban environment. Urban ecosystems are composed of human-built physical structures (e.g., buildings, roads, sewers, railways) and green patches (e.g., parks, greenways, urban streams). In general, urban ecosystems are highly disturbed and contain high levels of pollution. In urban areas, plant life is generally overrepresented by non-native and invasive species. Moreover, animal life primarily consists of pets (e.g., dogs, cats, ornamental birds, ornamental fish) and natural species adapted to human activities, which mainly include small animals (e.g., insects). Moreover, a forest ecosystem is defined as a natural woodland unit composed of 1-biotic factors such as plants (e.g., trees) animals (e.g., insects, birds) and micro-organisms, and 2-abiotic factors (e.g., water, oxygen, carbon, nitrogen, sulfur, etc). Forest ecosystems contain low or null levels of pollutants in the air, soil and water. Forest environments represent self-regulating systems that have not been altered or manipulated by human exploitation. In consequence, in forest ecosystems, non-human life is appropriately represented by native flora and fauna.

Which of the four factors that affect evolution apply to the finches that the Grants studied?Use evidence from your research to
BARSIC [14]
The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.

When a tick transfers Lyme disease from a deer to a human, the tick is considered the ________ in the chain of infection
melisa1 [442]

The tick is considered the vector in the chain of infection.

Generally, vector organisms are organisms that are capable of transmitting disease pathogens from infected organisms to uninfected ones either directly or indirectly as a result of their activities.

Ticks are parasites that feed on the blood of vertebrate animals such as deers and humans. When they feed on the blood of animals with certain infections, the pathogens for such infections are sometimes carried in the guts of the parasites and these are transferred to the bloodstream of the next animal that would be their host.

A good example of this is Lyme disease.

cestrela7 [59]

It is a very interesting question - the technology is real and the research on eDNA published in a journal in 2017.

eDNA stands for enviornmental DMA sampling. It allows scientist to test water samples for the presence of the DNA of the invasive fish species. It is more effective than traditional methods of sampling because it does not require trapping or sighting of the invasive species. Water samples can be collected anywhere any time and the DNA results are as accurate and detailed as collected from the invasive species themselves. It provides a complete picture of what invasive species are there.
