Answer 1

The type of data that would be necessary to consider the hypothesis that acid precipitation caused the loss of the salamander were, Acids that enter the atmosphere primarily affect ecosystems located less than 100 kilometers from the source of the pollution. Corrects answer: letter C.

Acid precipitation is known to affect ecosystems that are located near the source of the pollution. This is because acid precipitation can be carried through the atmosphere and deposited in the surrounding areas, affecting the habitats and species that are found there.

By determining the distances between the source of the pollution and the ecosystem where the salamander was lost, it can be determined if acid precipitation was likely to be a factor in its loss. Data would also be needed on the types and concentrations of acids that are found in the air near the source of the pollution and the salamander's ecosystem, as well as the pH levels in both areas.

Which of the following types of data would be required in order to consider the hypothesis that acid precipitation caused the loss of the salamander?

A) sulfuric acid and nitric acid from the burning of fossil fuels are the major causes of acid precipitation.

B) larger organisms lost from freshwater ecosystems because of acidification may not return even decades after ph values have returned to normal.

C)Acids that enter the atmosphere primarily affect ecosystems located less than 100 kilometers from the source of the pollution.

D) Though lakes are very sensitive to acidification, their ph can return rapidly to normal values.

E) regulation of emission sorces has raised the ph of precipitation in many parts of the eastern united staes in the last two decades.

INTRO TO CELL RESPIRATION OVERVIEW POGIL: All cells need energy all the time, and their primary source of energy is ATP. The methods cells use to make ATP vary depending on the availability of oxygen and their biological make-up. In many cases the cells are in an oxygen-rich environment. For example, as you sit and read this sentence, you are breathing in oxygen, which is then carried throughout your body by red blood cells. But, some cells grow in environments without oxygen (yeast in wine-making or the bacteria that cause botulism in canned food), and occasionally animal cells must function without sufficient oxygen (as in running sprints). In this activity you will begin to look at the aerobic and anaerobic processes that are used by all organisms to produce ATP. Which statement is NOT true based on this intro

Answers

The products formed as a result of cellular respiration are ATP, water and carbon dioxide.

The cells require energy to perform all their cellular functions. The source of energy for them is ATP which is adenosine triphosphate. The amount of ATP which is produced by a cell depends on its requirement and also on the amount of oxygen that is available.  

Depending on whether a particular organism requires oxygen or not, they can be classified as aerobic and anaerobic. Aerobic organisms are the ones which require oxygen whereas anaerobic organisms do not require oxygen. The reaction for cellular respiration can be represented as:

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP

Carbon dioxide, water and ATP are formed as products in this reaction.

Answers

The urinary problem caused by interference with the normal nerve pathways associated with urination known as neurogenic bladder.

Neurogenic bladder is a urinary problem caused by interference with the normal nerve pathways associated with urination. It is a condition wherein the nerves connected to the bladder do not function properly, which leads to difficulty in controlling the bladder and emptying it properly. This can lead to a wide range of symptoms, including difficulty in starting urination, an inability to empty the bladder fully, incontinence, and urinary tract infections.

The primary cause of neurogenic bladder is usually damage to the nerves that control the bladder. This can be due to a variety of conditions, including traumatic brain or spinal cord injuries, multiple sclerosis, Parkinson’s disease, stroke, and diabetes. In some cases, the underlying cause is unknown.

The symptoms of neurogenic bladder are usually the result of an inability to control the flow of urine. This can lead to an overactive bladder, which can cause frequent urges to urinate, even when the bladder is not full. In some cases, the inability to completely empty the bladder can lead to urinary retention, which can cause urinary tract infections. In addition, the condition can also cause incontinence, or the inability to control the flow of urine.

c. Fatty acids of less than 12 carbons enter the blood and then the liver via the portal vein.
d. Fatty acids of 16 or more carbons enter the lymphatic system directly and then enter the blood via the aorta.

Answers

The correct answer to the question is b. Fatty acids of less than 12 carbons enter the lymphatic system packaged in chylomicrons.

After absorption, fatty acids are taken up by the lymphatic system and transported in the form of chylomicrons. Chylomicrons are lipoproteins composed of lipids, proteins and other substances, and are the largest form of lipoproteins.

Chylomicrons are mainly composed of triglycerides and cholesterol esters, and are responsible for the transport of fatty acids from the small intestine to the rest of the body. These chylomicrons contain fatty acids of less than 12 carbons, which are then transported throughout the body via the lymphatic system.

Once the fatty acids reach the liver, they are either metabolized or stored as fats. In order to enter the blood, fatty acids of 16 or more carbons must be packaged in lipoproteins, such as very low density lipoproteins (VLDL). These VLDLs are then transported to the liver via the portal vein.

Why are there often so many steps between the original signal event and the cell's response?

Answers

This is because a variety of components must be integrated in order to accurately interpret and respond to the signal in a timely and effective manner.

The first step in this process is for the signal to be received and interpreted by the cell. This involves the binding of the signal molecule to a specific receptor, which triggers a cascade of cellular responses. This involves the activation of certain proteins, which then act as mediators of the signal within the cell and help to direct the response.

Once the signal has been received and interpreted, it must then be transmitted to the target organelle or region of the cell. This is done by a variety of molecules such as hormones, neurotransmitters, and growth factors. These molecules are released from the cell and travel to their target where they bind to specific receptors. This triggers a series of responses in the target organelle or region.

Finally, the cell must respond appropriately to the signal. This involves the activation of specific genes, which then produce proteins that alter the cells physiology and behavior. This is a process of gene expression that is tightly regulated and allows the cell to respond rapidly and accurately to the signal.

Answers

Paleontologists have been debating the origins of modern behavior, language, and art for decades. This debate has recently been reignited by the discovery of tools and artifacts at the Blombos Cave in South Africa.

The artifacts found at Blombos suggest that modern behavior, language, and art appeared in Europe approximately 50,000 years ago. However, some paleontologists argue that these behaviors are likely to have appeared much earlier.

I believe that modern behavior, language, and art were likely present in Europe long before 50,000 years ago. Looking at the archaeological record, it is clear that behavior, language, and art have been evolving since the time of our early ancestor Homo erectus. Furthermore, the tools and artifacts found at Blombos are similar to those found in other parts of the world, suggesting that these behaviors were not isolated to Europe.

In addition to the archaeological evidence, there is also genetic evidence that suggests modern behavior, language, and art existed in Europe before 50,000 years ago. Genetic studies of modern humans suggest that all modern populations share a common ancestor who lived approximately 150,000 years ago. This suggests that modern behaviors, language, and art were likely present in Europe at least 100,000 years ago.

There are many reasons why going to Mars is important. First, Mars is the most likely planet for us to colonize. No matter how expensive, we need to work on getting there as soon as possible. Furthermore, the technology that we would need to develop to send humans to Mars would directly benefit our economy here on Earth. Just look at the money-making products that have already resulted from NASAs space efforts: invisible braces, water filters, and cordless vacuums, to name just a few.Although we have already sent robots to Mars, robots cant take the place of humans when it comes to studying the planet. A robot may break down. Also, it takes robots much longer to cover the same amount of ground than it would a human. Think how much faster we could learn about the planet if we sent humans to work alongside the robots! Finally, claims that there will be significant health problems for people who travel to Mars are wrong. Studies have shown that radiation levels on Mars are not lethal to humans. Sure, we would have to live in a dome at first, but over time, we could use science to change the atmosphere and make it possible to go outside, just like on Earth! The choice is clear. We need to go to Mars now!Article 2MarsA Waste of Time and MoneyBy Juniper SpringsWhile it might be fun to imagine traveling to Mars one day, now is not the time to go. For one thing, it is too dangerous. The atmosphere of the planet is more carbon dioxide than oxygen, and its very cold. While there are claims that the radiation levels on the planet are not lethal to humans, that does not mean they arent dangerous. We dont yet know what the long-term health effects will be. As of now, we do not have a solution for this problem. It is foolish to think a dome would be able to protect us from all of the radiation.It would also be impossible to build one large enough to house as many people as they would want to go. Also, going to Mars will be expensive. Why spend money traveling to a planet that is so dangerous and far away? That money could be better spent addressing problems here on Earth.Furthermore, it is unwise to think any inventions resulting from our race to Mars would make up for the cost of getting there. We are already able to send robots to Mars. It wont be long until our technology is so advanced that a robot can do the same tasks as a human. It is not necessary to go to Mars right now.Part 1 Graphic OrganizerFill out the Compare and Contrast Chart based on the two articles in this worksheet.Comparison Chart.
