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.

What mineral is not included in children's multivitamin/mineral supplements because it is a major cause of unintentional poisoning deaths?

Answers

The correct answer is iron, because it is often not included in children's multivitamin/mineral supplements. Iron is an important element for our health. It is especially important for the proper functioning of our red blood cells and it is found in many foods. Although iron is essential, too much can lead to iron toxicity. Iron poisoning was the leading cause of death from the medicine overdose in children younger than 6 years until the ends of the 1990s. But the trend has since changed due to better warning labels, education of prescribers, changes in iron preparations, and consumer awareness.

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.

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.

_____ is a common nutrition-related sign or symptom of early pregnancy that occurs in many healthy pregnant women. question 19 options: fatigue hypertension gestational diabetes pernicious anemia

Answers

The right option is fatigue

Fatigue is a feeling of tiredness, lack of energy and motivation. Fatigue is a symptom of iron-deficiency anemia, which is common in pregnancy. During pregnancy, hormonal changes such as increased progesterone levels, physical changes and emotional changes occur in the body and this can contribute to decreased energy resulting in fatigue.

Final answer:

Fatigue, typically stemming from morning sickness due to elevated hormones, is a common nutrition-related symptom in early pregnancy. Hypertension and gestational diabetes usually occur later in pregnancy while pernicious anemia is not associated with pregnancy.

Explanation:

The common nutrition-related sign or symptom of early pregnancy mentioned in the question is likely fatigue. Fatigue can occur due to the body's reaction to the increased circulation of pregnancy-related hormones such as estrogen, progesterone, and hCG. These hormones can lead to symptoms such as nausea and decreased intestinal peristalsis, often referred to as 'morning sickness', which can persist all day and contribute to feelings of fatigue.

While hypertension and gestational diabetes can develop during pregnancy, they are not typically symptoms of early pregnancy. Pernicious anemia is not associated with pregnancy but is a condition where the body is unable to absorb vitamin B12 from the gastrointestinal tract.
