why is the cycling of matter essential to the continuance of life?

Answers

Answer 1

Answer: Biogeochemical cycles move matter from one organism to another and from living organisms to the abiotic environment and back again. The cycles of matter- carbon, nitrogen, phosphorus, sulfur and hydrologic- involve biological, geologic and chemical interactions. These five cycles are particularly important to organisms, because these materials make up the chemical compounds of cells.

Explanation: In the carbon cycle organisms fix, or incorporate, carbon from the atmosphere into chemical compounds through photosynthesis. Organisms also release carbon during cellular respiration. Other biological molecules that are not released during cellular respiration can be stored as fossil fuels for millions of years. Aquatic organisms incorporate Ca2+ and HCO3-  into their shells. When these organisms die, their shells sink to the ocean floor and become part of the sedimentary rock layer. The CO2 in these rock layers will later be released due to weathering or subduction. Atmospheric nitrogen is very stable and must be broken apart in order to combine with other elements. Bacteria are exclusively involved in all five steps of the nitrogen cycle, except assimilation. Nitrogen-fixing bacteria carry out biological nitrogen fixation in soil and aquatic environments. Soil bacteria perform nitrification, a two step process. First soil bacteria convert ammonia or ammonia to nitrite. Then other soil bacteria oxidize nitrite to nitrate. The process of nitrification furnishes these bacteria with energy. Ammonification begins when organisms produce nitrogen-containing waste products such as urea and uric acid. These substances, as well as the nitrogen compounds that occur in dead organisms, are decomposed, releasing nitrogen into the abiotic environment. Finally, denitrifying bacteria reverse the action of nitrogen-fixing and nitrifying bacteria by returning nitrogen to the atmosphere.

In the phosphorus cycle, plants roots absorb inorganic phosphates. Animals obtain most of their required phosphate from the foods they eat. Phosphorus is then released back into the soil when organisms die and decompose. In aquatic environments, phosphorus is

absorbed and assimilated by algae and plants, which are then consumed by plankton and larger organisms. A small portion of phosphate in the aquatic food web finds its way back to the land in the manure of sea birds.

A tiny fraction of the global sulfur is present in living organisms. Plant roots absorb sulfate and assimilate it by incorporating the sulfur into plant proteins. Animals assimilate sulfur when they consume plant proteins and convert them to animal proteins. Sulfur is returned to the atmosphere by bacteria which converts sulfates to hydrogen sulfide gas.

ap cal from edge. pls answer this question

Answers

Answer:

[tex]x = \frac{ln(k)}{5}[/tex]

Explanation:

Given

[tex]e^{5x} = k[/tex]

Required

Solve for x

[tex]e^{5x} = k[/tex]

Take natural logarithm of both sides:

[tex]ln(e^{5x}) = ln(k)[/tex]

Apply law of logarithm:

[tex]ln(e^{f(x)}) = f(x)[/tex]

So, we have:

[tex]ln(e^{5x}) = ln(k)[/tex]

[tex]5x = ln(k)[/tex]

Divide through by 5

[tex]x = \frac{ln(k)}{5}[/tex]

What social problems regard to the killing of Karen wood?

Answers

Answer:

Explanation:

Twenty years ago today, in a quiet backyard in Hermon, a hunter fired two shots that still reverberate in the minds of Mainers. A young mother of twin girls, Karen Wood, lay dead. Game wardens arrested Bangor hunter Donald Rogerson.

A husband had lost his wife. Two children had lost their mother. A hunter and his family saw their peaceful, structured lives descend into turmoil.

And as the national media descended upon Maine to tell the tragic story, an entire state lost its innocence.

No longer was Maine a quaint, quiet place to raise a family. Instead, in some circles the state was portrayed as a place where homeowners weren’t safe in their own backyards, where hunters were given carte blanche to shoot at will, and where shooting victims were blamed for contributing to their own deaths.

Twenty years later, Kevin Wood, the victim’s husband, is in Iowa. He has remarried. His twin daughters are in college.

Donald Rogerson still lives in Bangor with his wife. He’s a proud grandfather.

The social issue that can be picked from the death of Karen Wood is the lack of proper legislation on hunting activities.

In 1991, there was a hunter who fires shots and this led to the death of Karen Wood. The hunter who was Donald Rogerson was arrested by the game wardens.

Donald Rogerson was a deer hunter and his shot mistakenly led to the death of Karen Wood. The social issue in this case is a lack of proper legislation on hunting activities.

Hunting regulations would have been ideal as they will help prevent day hunting and in such a case, Karen Wood would not have died the way she did.

What type of outcomes does prison represent (positive reinforcement, negative reinforcement, positive punishment, negative punishment)? Justify your answer.

Answers

Answer:

negative punishment

Explanation:

Punishment  (positive or negative) decreases the chances that a particular behavioral reoccurs.

Handing a prison sentence to anyone that offends the laws of the state is an example of negative punishment based on available research. This is because, serving a prison sentence makes it more likely that the convict will commit the same crime again.

While many experts in criminal justice have observed that many ex-convicts tend to re-offend, the principles of positive punishment for convicts have been set out by Peter B. Wood in his paper titled "Exploring the Positive Punishment Effect Among Incarcerated Adult Offenders

"; American Journal of Criminal Justice 31(2):8-22; 2007; .

In his submission;

"As the U.S. has pursued a policy of mass imprisonment for nearly  three decades, now boasts the highest incarceration rate in the world and returns  nearly 800,000 ex-convicts into our communities each year, more attention to this  issue is called for-particularly since it could be argued that, for many offenders,  criminal justice punishments promote future offending."

If the unemployment rate is 5.8 percent and the number of unemployed persons is 15 million, the number of people who are employed is approximately



Answer : 244 million

Answers

Answer:

[tex]Employed =244\ million[/tex]

Explanation:

Given:

[tex]Unemployment\ Rate = 5.8\%[/tex]

[tex]Unemployed = 15\ million[/tex]

Required

Determine the number of employed persons.

First, we need to determine the labor force.

This is done as follows.

[tex]Unemployment\ Rate = \frac{Unemployed}{Labor\ Rate}[/tex]

Substitute values for. Unemployment Rate and Unemployed

[tex]5.8\% = \frac{15\ million}{Labor\ Rate}[/tex]

Solve for Labor Rate

[tex]Labor\ Rate = \frac{15\ million}{5.8\%}[/tex]

[tex]Labor\ Rate = 259\ million[/tex]

So, we have the labor rate to be.

[tex]Labor\ Rate = 259\ million[/tex]

Next, we calculate the employed people as follows

[tex]Employed = Labor\ Rate - Unemployed[/tex]

[tex]Employed = 259\ million - 15\ million[/tex]

[tex]Employed =244\ million[/tex]

Did it become more or less difficult to classify organisms as you moved down the taxonomy levels (Ex. Which was easier: classifying an organism into its kingdom or species)? Why do you think this is true? Explain your answer.

Answers

Answer:

The farther I moved down the taxonomy levels it becomes harder because at the top the classifications in the domain or kingdom are very broad. The farther you move down the more specific and detailed the classifications get. Also, there are many different groupings from the family classification to the subspecies classification which makes it harder for one to classify because of the about of precision you need to classify and put an organism into which ever group it goes into.

Explanation:

The taxonomy levels because the organisms in each group are more similar as you proceed from kingdom to species, making it difficult. They are more closely linked, which explains why.

What do you mean by the taxonomy levels?

Behavioral, genetic, and biochemical variances serve as the basis for classification. Taxonomy involves the processes of characterization, identification, and categorization.

Similar categories, including kingdom, phylum, class, order, family, genus, and species, are used to classify organisms.

Because the classifications in the domain or kingdom are so vast at the top, it gets difficult as I move down the taxonomy levels. The classifications become increasingly precise and in-depth as you descend.

Therefore, the taxonomy levels because the organisms in each group are more similar as you proceed from kingdom to species, making it difficult. They are more closely linked, which explains why.
