Which of the following changes to Earth is caused predominantly by living organisms?

A. The production of dirt.B. The release of free nitrogen into the atmosphere.C. The release of sulfur dioxide into the atmosphere.D. The movement of air currents by convection cells.

The production of dirt is cause predominantly by living organisms

This production can be caused through emission of pollution in the form of air, water, soil, noise or e-waste.

What is Pollution?

Pollution is defined as the introduction of unwanted harmful elements in the form of release of gaseous toxic substances which result into polluting the environment.

These pollutants can be both natural and anthropogenic.

Natural pollutants are volcanic ash, river sediments

Anthropogenic pollutants are chemicals released from industries vehicular emission.

Majorly pollution are of four types- Air, Water, Soil and Noise. Recently another pollution in the form of e-waste is also prominent.

Effects of pollution on environment:

1. Biomagnification describes situations where toxins (such as heavy metals)  passes through trophic levels, becoming exponentially more concentrated in the process.

2. Carbon dioxide emissions cause ocean acidification, the ongoing decrease in the pH of the Earth's oceans as CO2 becomes dissolved.

3. The emission of greenhouse gases leads to global warming which affects ecosystems in many ways.

4. Nitrogen oxides are removed from the air by rain and affect the land which can change the species composition of ecosystems.

5. Smog and haze can reduce the amount of sunlight received by plants to carry out photosynthesis and leads to the production of tropospheric ozone which damages plants.

6. Sulfur dioxide and nitrogen oxides can cause acid rain which lowers the pH value of soil.

7. Organic pollution of watercourses can deplete oxygen levels and reduce species diversity.

Rest three options are majorly natural process.

Option B focuses on release of free nitrogen into atmosphere which is one of the important step of Nitrogen Cycle.

Option C focuses towards release of Sulfur Dioxide into atmosphere. This process is caused either naturally or anthropogenically. Thus cant blame solely the anthropogenic factor for its release.

Option C is the total natural process i.e. Climatological Process where air currents are regulated by Convection Cells and regulate based on different natural factors.

Describe fluid exchange between capillaries and the interstitial fluid. Be sure to discuss the forces (pressure) that moves the fluid and the direction in which fluid moves. (4 points) In one to three sentences, describe the role of lymphatic system in this fluid exchange. (3 points) g

Answers

Answer:

Capillary exchange is the exchange of fluid from the capillaries into the interstitial fluid and vice versa. Diffusion, transcytosis, and bulk flow are three mechanisms that facilitate capillary exchange.

The blood plasma or interstitial fluid exerts a pressure of the fluid on the capillary walls known as Hydrostatic pressure. Osmotic pressure is a pressure exerted by proteins either in the blood plasma or interstitial fluid called oncotic pressure.

Lymphatic capillaries gather lymphatic fluid and regulate the pressure of interstitial fluid due to the forces of hydrostatic or oncotic pressure. An essential role of the lymphatic system is to return the fluid to the blood.

Question 19
How would the carbon cycle be influenced by an increase in aerobic respiration?

Answers

Answer:

Cellular respiration does not affect the carbon cycle but is part of the carbon cycle. The 2 carbon cycles. carbon ( C ) is taken up by the plants and trees in the form of carbon dioxide ( CO2 ). Plants converts this CO2 into organic compounds such as glucose ( C6H12O6 ).

Explanation:

Increase in aerobic respiration will lead to increase in the amount of CO2 released into to the atmosphere due to respiration.

Aerobic respiration occurs when oxygen is combined with glucose to yield carbon dioxide and water. This is one of the major ways through which carbon dioxide enters the carbon cycle.

Note that the carbon cycle shows the movement of carbon in nature. Increase in aerobic respiration means that more carbon will be introduced into the atmosphere as carbon dioxide.

Psychometric scores for anxiety, depression, negative self, somatization, and hostility were combined into a single Global Severity Index (GSI). Global Severity Index was compared for 80 adolescents who were seen in the outpatient clinic for 7 different physical complaints (short stature, obesity, lack of weight gain, breast problems, genital problems, menstrual problems, and hirsutism). Report the degrees of freedom for the relevant F statistic in the numerator and the denominator. (Round your answers to the nearest whole number.)

Answers

Answer:

The correct answer is -

Numerator = 6

Denominator = 73

Explanation:

In F static test or table there are two sets of degrees of freedom: one for the numerator and one for the denominator. The degrees of freedom are equal to the number of observations minus one. Thus, if the sample size were 7 then the degree of freedom would be 7 minus 1

Numerator df = 7 - 1 = 6

Thus, the numerato would be - 6.

Denominator is calculated by subtracting the observation or variables from the total number of sample size.

Denominator df = 80- 7 = 73

At this point, the writer is considering adding the following sentence. Successful nerve impulse transmission depends not only on myelin sheaths, but also on the presence of ion pumps embedded in the cell membrane. Should the writer make this addition here?
A) Yes, because it describes how the presence of ion pumps is related to the functions of cholesterol.
B) Yes, because it supports the passage’s main argument with a second example of cholesterol’s potential adverse health effects.
C) No, because it identifies a relationship between the nervous system and ion pumps that has already been discussed.
D) No, because it interrupts the paragraph’s discussion of cholesterol’s functions with loosely related information.

Answers

Answer:

D) No, because it interrupts the paragraph’s discussion of cholesterol’s functions with loosely related information.

Explanation:

The passage was discussing the importance of cholesterol in nerve impulse transmission. Its presence in the myelin sheaths of nerve cells speeds up nerve impulse transmission. It will not be wise for the author to now bring in the relationship between nerve impulse transmission and ion pumps. This is because the main topic under discussion is cholesterol and its importance. The sentence should be continued with other importance of cholesterol and not ion pumps.

The term voltage describes the:
-electrical potential difference between two points.
-likelihood that an electrochemical gradient will develop.
-process of molecules moving from an area of high concentration to low
concentration.
-way in which osmosis determines water movement.

Answers

Answer:

electrical potential difference between two points.

Explanation

Voltage refers to the electrical potential difference between two distinct points. It doesn’t describe the way in which osmosis determines water movement (osmotic pressure), nor does it describe the process of molecules moving from an area of high concentration to low concentration (diffusion), or the likelihood that an electrochemical gradient will develop.

The term voltage describes the electrical potential difference between two points. Option A is correct.

Voltage is a measure of the amount of energy that is available to move electrons from one point to another. It is measured in volts (V). The higher the voltage, the more energy is available to move electrons.

The electrical potential difference between two points is created by the difference in the number of electrons at those two points. If there are more electrons at one point than at another, there will be a voltage difference between the two points. This voltage difference will cause electrons to flow from the point with more electrons to the point with fewer electrons. Option A is correct.

if 5^t = 0.04 ,then find the value of t Read the passage from Animal Farm.Meanwhile life was hard. The winter was as cold as the last one had been, and food was even shorter. Once again all rations were reduced, except those of the pigs and the dogs. A too rigid equality in rations, Squealer explained, would have been contrary to the principles of Animalism. In any case he had no difficulty in proving to the other animals that they were NOT in reality short of food, whatever the appearances might be. For the time being, certainly, it had been found necessary to make a readjustment of rations (Squealer always spoke of it as a "readjustment," never as a "reduction"), but in comparison with the days of Jones, the improvement was enormous. Reading out the figures in a shrill, rapid voice, he proved to them in detail that they had more oats, more hay, more turnips than they had had in Jones's day, that they worked shorter hours, that their drinking water was of better quality, that they lived longer, that a larger proportion of their young ones survived infancy, and that they had more straw in their stalls and suffered less from fleas. The animals believed every word of it. Truth to tell, Jones and all he stood for had almost faded out of their memories. They knew that life nowadays was harsh and bare, that they were often hungry and often cold, and that they were usually working when they were not asleep. But doubtless it had been worse in the old days. They were glad to believe so. Besides, in those days they had been slaves and now they were free, and that made all the difference, as Squealer did not fail to point out.How does this passage demonstrate the use of propaganda? Select two options.It demonstrates repetition because Squealer reminds the animals that they are free at the farm because of the work they are doing.It demonstrates hyperbole because Squealer exaggerates the figures related to positive developments of the farm.It demonstrates bandwagon because Squealer convinces the animals that life is better now than it was before, and everyone agrees because the report says so.It demonstrates plain folks because Squealer explains why the pigs and dogs deserve better food rations than the other animals.It demonstrates glittering generalities because Squealer does not explain the claim that equality in rations would be contrary to the farms ideals. which state of matter expands most when heated If 6x + 5y = 10, what is y in terms of x?Please include an explanation!
