EXPLAIN Make a claim about the affect urbanization has on
biodiversity. Does urbanization always decrease biodiversity? Use
evidence to support your claim and explain your reasoning. Address
the following questions in your answers
• What are the main factors that lead to biodiversity loss in urban
areas?
• How is the size of a habitat related to its biodiversity and its stability?
• Can an ecosystem in an urban area ever return to its previous state?

Answers

Answer:

Urbanization decreases biodiversity. Land development reduces the size of habitats and affects the availability of resources. Larger habitats have a greater potential for biodiversity. If some of the natural habitat is retained, the impact of urbanization may not be as destructive. Assuming human development and its resulting pollution aren’t too extensive, an abandoned urban area could return to its previous ecosystem.

Explanation:

It is found that urbanization affects the biodiversity and the relationship between them is not linear as with the increase in urbanization the area of forest keeps on decreasing which reduces the natural habitat of many species and lead to their extinction.

What affects biodiversity?

Biodiversity of an area is the total number of living organisms (species) living in a particular area. Most of the biodiversity are found in the forests as these are the natural habitats of many animal species.

The ecological studies conducted on the urbanization and biodiversity have found that the urbanization generally shows a negative impact on the biodiversity levels of an area. The relationship between biodiversity and urbanization is not always a linear relation. As the area of urban citied increases, the area of forest decreases which lead to extinction of many important species.

The forests are the natural habitat of animals, as the natural habitat decreases the biodiversity of an area also decreases which affects the stability of the forest.

An ecosystem in an urban area can be returned to a biodiversity-rich area by introducing species and making the habitat more favorable for them.

Which of the following was the leading cause of global fossil carbon emissions in 2004?
a. petroleum
b. coal
c. natural gas
d. cement production

Answers

Answer:

The answer is a. petroleum

Explanation:

I just took the test and got it right.

The leading cause of global fossil carbon emissions in 2004 was petroleum. Thus, the correct option for this question is A.

What is Carbon emission?

Carbon emission may be defined as the process of liberation of greenhouse gases like carbon dioxide and/or their precursors into the atmosphere over a specified area and period of time. These emissions are significantly contributing to climate change across the world.

When it comes to the global fossil carbon emissions in 2004, the major cause of that was due to petroleum. During that time, people utilize a large amount of petroleum in burning activities. This stimulates the rate of carbon emission in the entire atmosphere which is harmful to the health of living organisms.

Therefore, the leading cause of global fossil carbon emissions in 2004 was petroleum. Thus, the correct option for this question is A.

Researchers are investigating the incidence of algal blooms in neighborhood ponds. In summer, they collect water samples from over 100 neighborhood ponds in Dallas, Texas and surrounding cities. They also surveyed residents in each neighborhood to collect data such as average lot size, average home value, average resident income, and lawn care methods. The researchers found that neighborhoods with large lots, high home values, and high income levels were likely to use automatic sprinklers and synthetic fertilizers on their lawns. These same neighborhoods were very likely to have abundant algae in their ponds. Based on this research, which conclusion provides the best explanation for why algae proliferate in neighborhood ponds?

Answers

Answer:

Excessive synthetic fertilizer that washes into ponds may be the reason for which algae become so abundant.

Explanation:

Algal blooms that feed on fertilizers can deplete oxygen in water, thereby producing inhospitable ponds. In this regard, it has been shown that the runoff of fertilizers from farms (which are rich in nitrogenous matter) may cause algae to become abundant in coastal environments, depleting oxygen in the water and killing the living organisms that inhabit these areas.

Answer:

They're the Youngest. This information also suggests that Archaeopteryx was once thought to be the oldest known fossil bird.

Explanation:

Based on the principle of superposition, we can conclude that the topmost layer is the youngest. Hence, the fossil of birds is the youngest, while Archaeopteryx is younger than dinosaur fossil.

According to the principle of superposition, sedimentary deposits are layered such that, the oldest layer is at the bottom and the youngest is the topmost layer.

Hence, dinosaur fossil are the oldest, followed by Archaeopteryx, then birds.

If a neuron receives a weak excitatory stimulation and a strong inhibatory
stimulation just around the same time, will the neuron fire?
O No becuae the inhibitory stimulation was strong

Yes because the inhibitory neuron was strong

No because the excitatory stimulation was strong

O Yes because the excitatory neuron was strong

Answers

We are essentially considering the summation of a weak excitatory postsynaptic potential (EPSP) and a strong inhibitory postsynaptic potential (IPSP). Since both signals are received around the same time, the stronger signal will dominate—in this case, the inhibitory stimulation. Assuming that the signals are of different magnitudes, the neuron will most likely not fire because the excitatory stimulation was too weak or because the inhibitory signal was strong[er] than the excitatory signal.

The former is not among the answer choices. Thus, the most likely answer is the first choice: “No, because the inhibitory stimulation was strong.”
