why is non point source pollution of an aquatic ecosystem

Answers

Final answer:

Nonpoint source pollution accumulates from diverse areas, contributing to eutrophication in aquatic ecosystems. This form of pollution is more challenging to control than point source pollution because it does not have a single, identifiable origin.

Explanation:

Nonpoint source pollution (NPS) is contamination that does not originate from a single, identifiable source. In contrast to point source pollution, which enters the environment from well-defined, discrete locations, nonpoint source pollution accumulates from a wide array of sources over large areas and is often carried into water bodies through runoff.

Eutrophication is a process resulting from an overabundance of nutrients in water bodies, often due to runoff containing phosphates and nitrates. This nutrient overload supports excessive growth of algae and microorganisms, which can lead to oxygen depletion and negatively impact aquatic life.

It is essential to control both point and nonpoint source pollution to maintain water quality. However, nonpoint source pollution presents greater challenges for regulation and mitigation due to its widespread and diffuse nature.

Final answer:

Nonpoint source pollution is widespread and diffused aquatic ecosystem contamination from various small sources, leading to issues like eutrophication, which harms aquatic life by depleting oxygen.

Explanation:

Nonpoint source pollution of an aquatic ecosystem refers to contamination that accumulates from multiple, often diffuse sources rather than a single, identifiable location. In contrast to point source pollution, which might come from a single discharge pipe from a factory, nonpoint source pollution involves pollutants such as herbicides, pesticides, fertilizer, oil, and road salt being washed into water bodies from widespread areas like agricultural fields, cities, or abandoned mines. Eutrophication is a process where increased nutrients, particularly nitrogen (N) and phosphorus (P), lead to an overgrowth of algae and negative impacts on water quality and aquatic life, such as fish, by depleting oxygen levels. Since nonpoint source pollution is widespread and diffused, it's much harder to regulate and manage compared to point source pollution.

A 64 year-old man has a past medical history of two strokes and diabetes. his dementia started four weeks after his first stroke and got worse after in his next stroke. he is most likely afflicted with:

Answers

The answer would be vascular dementia

There are several causes of dementia, one of them is vascular. Vascular dementia happens because of damage to the blood vessels that cause reduced oxygen and nutrient to the brain. The cause could be hypertension, diabetes, or stroke. The patient in this problem has dementia that got worse after stroke, so it is more likely to be vascular dementia.

Final answer:

The 64-year-old man with a history of strokes and diabetes likely has multi-infarct dementia or post-stroke dementia, which are forms of dementia resulting from cumulative brain damage due to strokes rather than Alzheimer's disease.

Explanation:

A 64-year-old man with a past medical history of two strokes and diabetes, whose dementia started four weeks after his first stroke and worsened after a subsequent stroke, is most likely afflicted with multi-infarct dementia or post-stroke dementia. Alzheimer's disease is a common type of dementia that typically develops slowly and affects memory, language, and cognition. However, since this man's dementia symptoms developed shortly after his strokes and he has diabetes (a risk factor for vascular issues), it is more likely that his cognitive decline is due to the strokes rather than Alzheimer's disease. This is consistent with the fact that about 20% of individuals who experience an ischemic stroke will develop dementia within six months following the event. Both multi-infarct dementia and post-stroke dementia are linked to cerebrovascular problems, including transient ischemic attacks (mini-strokes), which cumulatively cause brain damage and cognitive decline.

How does cocaine induce a sense of exhilaration? by decreasing the activity of the main excitatory neurotransmitter in the brain by producing a long but mild sense of euphoria by increasing the higher social regulatory functions of the cerebral cortex by increasing the availability of dopamine and serotonin in synapses?

Answers

Cocaine induces a sense of exhilaration by increasing the availability of dopamine and serotonin in synapses. Cocaine is among the powerful stimulants which increase the release of neurotransmitters such as nor-epinephrine, dopamine and serotonin, that affect CNS and PNS activity. Cocaine administration constricts blood vessels that are absorbing it, son snorting it is a slow way to deliver it to blood stream and eventually the brain.

Final answer:

Cocaine creates a sense of exhilaration by preventing the reuptake of dopamine in the brain, which stimulates the pleasure centers leading to a euphoric "high". This is followed by a rapid depletion of dopamine, causing cravings for the drug.

Explanation:

Cocaine induces a sense of exhilaration by increasing the availability of dopamine and serotonin in synapses. It acts as a stimulant by preventing nerve cells from reabsorbing dopamine, thus allowing high levels of this neurotransmitter to stimulate the pleasure centers of the brain. This enhancement of dopamine action is responsible for the euphoric "high" associated with cocaine use, as well as its addictive properties. After use, dopamine levels are quickly depleted, leading to a craving for more cocaine to regain the pleasurable sensation.

What is the process of water moving through the soil called answers?

Answers

The process of water moving through the soil is called percolation or ground water recharge. In this process water oozes, seeps, or filter through the soil beneath the surface, without a defined channels, or in a course that is unknown and not discoverable from surface indications without excavation for that purpose. Percolation and infiltration are two related but different processes describing the movement of water through the soil. Infiltration involves the downward entry of water into the soil or rock surface while percolation is the flow of water through soil and porous or fractured rock.

Final answer:

Water moving through the soil is called percolation. This water can be used by plants for metabolism or evaporate from leaf stomata, in a process called evapotranspiration. Remaining water infiltrates the subsoil and bedrock, forming groundwater.

Explanation:

The process of water moving through the soil is referred to as percolation. During rainfall, significant water is lost through evaporation from plant surfaces. The remnant water reaches the soil and starts to move downwards. When the soil is saturated from a heavy rainfall, surface runoff occurs. Most of this soil water is absorbed by plant roots for the plant's metabolism. A substantial proportion of this water is lost to the atmosphere through a process called evapotranspiration, which involves water entering the plant's vascular system through the roots and evaporating from the leaf stomata. The water in the soil that does not evaporate and is not used by the plants can infiltrate the subsoil and bedrock, turning into groundwater.

how would relaxing the smooth muscles in arteries affect blood pressure ?

Answers

When you relax the smooth muscles in arteries, it affects the blood pressure quite a lot. If you're a up and running person, you're most likely not always relaxed. Although - if you manage to relax, it would cause your blood pressure to lower from a high rate, to a much lower rate. That's the main outcome of this.

Answer:

Relaxing the smooth muscles in arteries would lower down the blood pressure.

Explanation:

Smooth muscles are present in lining of blood vessels. Relaxing the smooth muscles in arteries causes vasodilation, that is, the cavity of arteries is widened. Dilated arteries allow more blood to pass through them and lower down the blood pressure. Constriction of smooth muscles of arteries causes vasoconstriction and increases blood pressure.

Some geologists hypothesize that the mass extinction of dinosaurs was caused by a large meteorite impact. These geologists think the meteorite impact significantly changed Earth's climate. How could a meteorite impact do this?

Answers

The meteorite was probably 10 to 15 km (6.2 to 9.3 mi) wide and affected the entire planet through a proces called "impact winter". As the name suggests, an impact winter is a period of low temperature produced by a huge cloud of ash and dust that blocks sunlight. Since sunlight is essential for plants to survive, if the sun rays are blocked by this cloud, all animals that depend on those plants (including dinosaurs) will die. The meteorite could have created such a cloud upon hitting the earth.

Infact the meteor only had a 13% chance to hit the earth and make ash and soot fly into the air

Increasing the number of windings and making them smaller will increase the strength of an electromagnet.

How often would a restriction enzyme such as not i which has 8 nucleotides?

Answers

how often would a restriction enzyme such as NotI, which has 8 nucleotides in its recognition sequence sites 5'-GCGGCCGC-3' cleave DNA on average? Explain.

It would cleave DNA on an average of once every 2050 base pairs because it is less common the higher number of base pairs in the recognition sequence

hope this helps

A restriction enzyme such as Not I, which recognizes an 8-nucleotide sequence, would be expected to cut a DNA molecule approximately once every 65,536 base pairs (bp), according to the mathematical probability of occurrence of a specific sequence of nucleotides in a random distribution of DNA.

Restriction enzymes are specialized proteins that identify specific, short sequences of DNA and cut the molecule at those precise locations. The frequency at which a particular restriction enzyme cuts the DNA depends on the length of its recognition sequence. Since there are four types of nucleotide bases (adenine, cytosine, guanine, and thymine), each position in the sequence has a 1 in 4 chance of being any particular base. Therefore, the probability of an 8-nucleotide sequence occurring is (1/4)8, or 1 in 65,536 for any random segment of DNA. The enzyme Not I, for instance, would theoretically generate a cut once in every 65,536 base pairs in a stretch of DNA. However, the actual frequency can vary due to non-random base composition and other factors like DNA methylation that can inhibit enzyme activity.

Nuclear dna can be extracted from bones and teeth to determine personal identification. if, however, the nuclear dna is degraded or damaged, there is another substance which is more plentiful and durable that can be analyzed. what is the name of this substance?

Answers

The name of the other substance that is more plentiful and durable that can be analyzed is the mitochondrial DNA. Nuclear DNA is located within the nucleus of eukaryotes cells and usually have two copies per cell, while mitochondria DNA is located in the mitochondria, which are organelles that convert energy from food into a form that cells can use.

Final answer:

When the nuclear DNA is degraded or damaged, mitochondrial DNA (mtDNA) is often used in its place for analysis. This is because it's more plentiful and durable. MtDNA is a crucial tool used in fields such as anthropology and forensics for studies related to human evolution, migration patterns, and personal identification.

Explanation:

In scenarios where nuclear DNA is degraded or damaged, mitochondrial DNA (mtDNA) can be analyzed. This is because mtDNA is more durable and plentiful compared to nuclear DNA. Since it is passed down from mothers to their offspring without recombination, mtDNA can be traced back to a common female ancestor known as 'Mitochondrial Eve'.

MtDNA is useful in determining the divergence of various human populations. Its mutation rate is higher than that of nuclear DNA, making it a good tool for tracking changes in a relatively short evolutionary timeframe. Hence, it's applied extensively in anthropological studies and forensics. Professionals in these fields can use mtDNA to gain a substantial amount of information about human evolution, migration patterns, and individual identification.

While nuclear DNA provides a genetic blueprint for individuals or species, in cases where it is damaged or unavailable - such as from ancient or degraded samples – mitochondrial DNA provides a reliable alternate source of genetic information.
