so-called dead zones in coastal oceans are associated with nutrient runoff and oxygen-depleted bottom waters. what causes the oxygen depletion?

Answer:

weather conditions

Explanation:

Climate change is expected to be the main cause of mass extinctions in the 21st century and dolphins are not exempted. The swift warming of the planet leads to a loss of habitat for dolphins and increase competition for a lessening amount of prey species. It disturb the timing and ranges of their migration, distribution and ability to reproduce.

Some dolphins may not be able to survive and limit the ability to move northwards into cooler habitat as waters become warmer.

Based on their locations, you would expect the biggest change between the weather in the summer and the weather in the winter in Winnipeg. Here option A is the correct answer.

Winnipeg is located in the Prairie region of Canada and it has a continental climate characterized by cold, snowy winters, and warm summers. Vancouver is located on the west coast of Canada, it has a mild oceanic climate with milder winters and less hot summers.

San Diego is located on the coast of California and has a Mediterranean climate characterized by mild, wet winters and hot, dry summers. The change in temperature between the summer and winter in Winnipeg is the most significant, with average summer temperatures around 20-25C and winter temperatures around -20C or below.

This is a much greater change than the temperature variation in Vancouver and San Diego, which have milder temperature variations throughout the year.

When the pressure of a fluid is increased, its flow rate will increase as well. Likewise, when the pressure of a fluid is decreased, the flow rate of the fluid will decrease.

This is based on the fact that pressure has a direct influence on the flow rate of fluids. This concept is known as Bernoulli's principle. Bernoulli's principle says that when a fluid moves through a pipe, the pressure it experiences changes based on the flow rate of the fluid. When the flow rate of the fluid is high, the pressure of the fluid decreases. When the flow rate of the fluid is low, the pressure of the fluid increases. As a result, if the pressure of a fluid is changed, the flow rate of the fluid will be affected. This was shown in an experiment where the pressure was increased or decreased by a small amount, and the resulting flow rate was measured. The results of this experiment were consistent with the predictions of Bernoulli's principle, showing that pressure changes have a direct impact on flow rate.

Acid deposition is the deposition of acidic compounds from the atmosphere to the Earth's surface. It is caused by natural sources like volcanoes and human activities such as burning fossil fuels. Chemical equations include \(SO_2\) + \(O_2\) + \(H_2O\) → \(H_2SO_4\) and NOx + \(O_2\) + \(H_2O\) → \(HNO_3\). Acid deposition can be wet or dry, harming ecosystems and causing damage to structures. The effects of acid deposition are far-reaching. It can lead to the acidification of lakes, rivers, and soils, which can harm aquatic ecosystems and affect the growth and survival of plants and animals. Acid deposition can also damage buildings, statues, and monuments made of limestone or marble, as these materials are particularly susceptible to erosion by acids.

Acid deposition refers to the deposition of acidic compounds from the atmosphere onto the Earth's surface.

Sources of acid deposition include natural sources like volcanic emissions and the oxidation of sulfur and nitrogen compounds, as well as human activities like burning fossil fuels.

The chemical equations involved in acid deposition formation are:

  a. Formation of sulfuric acid: \(SO_2\) + \(O_2\) + \(H_2O\) → \(H_2SO_4\)

  b. Formation of nitric acid: NOx + \(O_2\) + \(H_2O\) → \(HNO_3\)

Acid deposition can be classified into two types: wet deposition and dry deposition.

  a. Wet deposition occurs when acidic pollutants dissolve in precipitation and are deposited onto the Earth's surface.

  b. Dry deposition happens when acidic particles and gases settle directly onto the ground or other surfaces without being dissolved in precipitation.

The effects of acid deposition include the acidification of lakes, rivers, and soils, which can harm aquatic ecosystems and affect plant and animal life. It can also cause damage to buildings, statues, and monuments made of limestone or marble.

A visual representation of the sources, formation, and precipitation of acid deposition can be illustrated through a diagram or drawing. This can show the emission sources, chemical reactions, and the deposition of acidic compounds onto the Earth's surface.

The oxygenation of atmosphere is major event (or events) likely allowed eukaryotes to evolve. The current atmosphere is oxidizing because it has a lot of oxygen in it. The increase in oxygen is credited to cyanobacteria, which are considered to have first emerged some 3.5 billion years ago and are responsible for photosynthesis.

Blue-green algae, often known as cyanobacteria, are the cause. These microbes make carbohydrates and, yes, oxygen through photosynthesis, which involves using sunlight, water, and carbon dioxide. Thus, the oxygenation released by cyanobacteria led to modifications in the composition of the earth's atmosphere, the emergence of aerobic metabolism.

The segmented income statement for Shannon Company shows the sales, variable expenses, contribution margin, allocated common fixed expenses, and net operating income for each division. The percentages are calculated by dividing each item by the total sales and multiplying by 100. This segmented statement provides a clear view of the financial performance of each division and the company as a whole.

Segmented income statements provide a detailed breakdown of the financial performance of different divisions or segments within a company. In this case, we have Shannon Company, which consists of two divisions: North and South. The overall sales, contribution margin ratio, and net operating income for the company as a whole are $810,000, 32%, and $16,200, respectively. The North Division has a contribution margin of $111,600 and a contribution margin ratio of 36%, while the South Division's segment margin is $105,000. Additionally, there are $170,100 of common fixed expenses that cannot be traced to either division.

To prepare the segmented income statement, we need to allocate the common fixed expenses to the two divisions. The allocated expenses will be subtracted from the segment margins to arrive at the net operating income for each division. Here is the segmented income statement for Shannon Company:

A mechanism of succession in which the presence of one species increases the probability that a second species can become established is Facilitation.

What is Facilitation?

Facilitation describes interactions in which one or both species gain, but none is damaged. The two different forms of facilitation are mutualism and commensalism.

According to the facilitation model, the existence of an initial species promotes and raises the likelihood of the development of a second species. For instance, in an Alaskan floodplain, the presence of alder trees promotes the growth of willow and poplar seedlings. The nitrogen-fixing bacteria found in alder roots significantly enhance the quantity of inorganic nitrogen found in soils. In places without significant competitors, this increased nitrogen availability promotes the growth of both willow and poplar seedlings.

Elastic connective tissue is a type of connective tissue made up of elastic fibers, fibroblasts, and collagen. It is found in the lungs, walls of arteries, and bronchial tubes, and is composed of a dense network of elastin fibers that make the tissue elastic, permitting it to stretch and return to its initial shape repeatedly.
