Which of the following is a tool that is best used to measure the oxygen in water?​

Answers

Answer 1

Answer:

DO is measured using a dissolved oxygen meter (or DO meter). The best method is to take the measurement in the field at the same time each day, because DO concentrations can vary throughout a 24 hour period.

Answer:

Explanation:

The analysis of data gathered during a particular experiment is necessary in order to arrive at a conclusion that will address the aim of the experiment.

Without data analysis, valid conclusions about the experiment cannot be made and what the experimenter would have is just raw data that cannot say or answer anything about the experiment.

The data collected from experiments can be analyzed in two ways:

Descriptive data analysis Inferential data analysis

In descriptive data analysis, the collected data is summarized, arranged, or described in such a way that a pattern can be seen at a glance. It includes tables, charts, histograms, etc.

In inferential data analysis, the collected data is treated in such a way that an inference can be arrived at based on the study. This includes testing for a significant difference between means, testing for the goodness of fits, correlations, etc.

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.

What is Solar radiation?

Solar radiation may be defined as a type of electromagnetic radiation which is constantly emitted from the sun. Such type of radiation can be captured and transformed into useful forms of energy, such as heat and electricity through the utilization a variety of technologies.

The process of regulating the temperature initiates with the absorption of solar radiation during the daytime, due to this, the temperature of the daytime remains moderate.

This absorbed radiation at night time liberates heat. This liberated heat at night prevents the water to freeze for this specific duration.

Therefore, the correct order to explain how water regulates the planet’s temperature is briefly mentioned above.

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.

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.
