Answer:

Reducing the intensity of runoff.

Explanation:

Terrace farming prevent landslides and erosion to occur by reducing the intensity of runoff. This farming also reduce the risk of drought due to raising the moisture content in the soil and allowing water to slowly infiltrate into the soil. Due to terrace farming, the runoff water moves very slowly which causes less erosion of the soil as well as reduces the intensity of water flow which causes more infiltration.

Living organisms involved in the nitrogen cycle:

Nitrogen-Fixing Bacteria

Nitrifying Bacteria

Denitrifying Bacteria

Plants

Non-living components involved in the nitrogen cycle:

Atmospheric Nitrogen

Ammonia (NH3)

Nitrites (NO2-) and Nitrates (NO3-)

These living and non-living organisms work together in a complex web of interactions to facilitate the conversion and cycling of nitrogen throughout ecosystems, ensuring the availability of this essential element for various organisms.

The nitrogen cycle is a complex process that involves both living and non-living organisms.

Living Organisms:

1)Nitrogen-Fixing Bacteria: These bacteria, such as Rhizobium and Bradyrhizobium, convert atmospheric nitrogen (N₂) into ammonia (NH₃) through a process called nitrogen fixation.

They form symbiotic relationships with certain plants, like legumes, and reside in root nodules, providing plants with a source of fixed nitrogen.

2)Nitrifying Bacteria: Nitrifying bacteria, including Nitrosomonas and Nitrobacter, convert ammonia (NH₃) into nitrite (NO₂⁻) and then into nitrate (NO₃⁻).

This process is known as nitrification and provides usable forms of nitrogen for plants.

3)Denitrifying Bacteria: Denitrifying bacteria, such as Pseudomonas and Paracoccus, perform denitrification, a process that converts nitrate (NO₃⁻) back into atmospheric nitrogen (N₂), completing the nitrogen cycle. Denitrification occurs in oxygen-deprived environments.

Non-living Components:

1)Ammonification: Ammonification is the process of organic nitrogen compounds, such as proteins and urea, being broken down by decomposers (e.g., bacteria and fungi).

These organisms convert the organic nitrogen into ammonia (NH₃), which can be further utilized in the nitrogen cycle.

2)Lightning: Atmospheric nitrogen (N₂) can be directly converted into nitrogen oxides (NOₓ) through lightning strikes.

Nitrogen oxides eventually dissolve in rainwater, forming nitrate ions (NO₃⁻), which can be taken up by plants.

3)Abiotic Reactions: Nitrogen can undergo abiotic processes such as atmospheric deposition and runoff, where nitrogen compounds are transported from the atmosphere or terrestrial systems into aquatic ecosystems.

These inputs contribute to the overall availability of nitrogen for aquatic organisms.

Answer:

Explanation:

Meristems are regions in plants where active cell division occurs, resulting in the growth of new plant tissue.

Apical meristems are located at the tips of roots and shoots and are responsible for primary growth in plants.

Apical meristems are important because they are responsible for the growth of new tissues that give rise to leaves, stems, and roots, which are essential for plant growth and development.

The growth of new plant tissue is caused by the continuous activity of apical meristems, which divide and differentiate to form new cells and tissues.

The shoot apical meristem produces structures such as leaves, stems, and flowers as its cells divide by mitosis.

Tropism is the growth response of a plant to a particular environmental stimulus.

Two types of tropisms are phototropism, which is the growth response of plants to light, and gravitropism, which is the growth response of plants to gravity. In phototropism, plants respond to the direction and intensity of light by growing towards it, while in gravitropism, plants respond to the direction of gravity by growing either towards or away from it.

The main group of plant hormones are auxins, gibberellins, cytokinins, abscisic acid, and ethylene.

The main functions of plant hormones include regulating growth and development, controlling tropisms, responding to environmental stimuli, and coordinating plant responses to stress.

Auxin influences gene expression by binding to specific receptors in the nucleus of cells, which leads to changes in gene expression that regulate cell growth and differentiation.

Micropropagation is a technique used to produce large numbers of plants from a small amount of tissue.

Micropropagation is done by culturing plant tissue in vitro, under sterile conditions, and providing it with the necessary nutrients and plant hormones to stimulate growth and development.

Micropropagation is done for several reasons, including the production of disease-free plants, the preservation of rare or endangered species, and the rapid propagation of genetically identical plants for commercial purposes.

The presence of trees can have both erosive and protective effects on a mountain formation. Trees help to prevent erosion by providing shade, trapping sediment, and stabilizing the soil with their roots. On the other hand, their presence can also promote erosion by intercepting rainfall and increasing water velocity, thus increasing erosion. They can also cause the formation of gullies, which can lead to the erosion of deeper layers of soil.

Answer:

If trees were added to a mountain formation, they were likely added as a measure to prevent erosion rather than being an agent of erosion themselves. Trees have roots that can help stabilize soil and prevent erosion from occurring.

When rain falls on a bare mountain slope, it can cause the soil to erode and wash away, leading to landslides and soil instability. However, when trees are present, their roots hold the soil in place, making it less likely to wash away. The trees also help to absorb some of the water, reducing the amount of runoff that can contribute to erosion.

In addition to preventing soil erosion, trees can also help to prevent other forms of erosion, such as wind erosion. The leaves and branches of the trees can act as a barrier, slowing down the wind and reducing its ability to erode the soil.

In summary, trees are typically used as an agent to prevent erosion rather than as an agent of erosion. Their roots stabilize the soil, and their presence reduces the amount of water and wind erosion that can occur.

Answer:

The coefficient of interference, I, is 0.1 (10% expressed as a percent)

Explanation:

Available data:

The coefficient of interference, I, is complementary with CC.

I = 1 - CC

To calculate the coefficient of coincidence, CC, we must use the next formula:

CC= observed double recombinant frequency/expected double recombinant frequency    

Note:  

By knowing the positions of genes, we can estimate the distances in MU between them per region.

Now that we know the distances, we can estimate the recombination frequencies by dividing each distance by 100.

Now that we know the recombination frequencies in each region, we can calculate the expected double recombinant frequency, EDRF, like this:

EDRF = recombination frequency in region I x recombination frequency in region II.

EDRF = 0.13 x 0.06 = 0.0078

Now, by knowing the total number of individuals in the progeny (1000) and the number of double crossovers (7), we can calculate the observed double recombinant frequency, ODRF:

ODRF = number of double crossovers / total number of individuals

ODRF = 7/1000 = 0.007

Finally, with the values of EDRF and ODRF, we can calculate the coefficient of coincidence, CC.

CC = ODRF/EDRF

CC =  0.007 / 0.0078

CC = 0.9

And by knowing the CC we can also get the coefficient of interference, I.

I = 1 - CC

I = 1 - 0.9

I = 0.1 = 10% (expressed as a percent)

Both dichotomous keys and genetics (DNA) can be used as tools to classify organisms, but the accuracy of classification depends on the context in which they are used.

Dichotomous keys are useful for identifying and classifying organisms based on observable physical characteristics, such as their shape, color, size, and other morphological features. These keys work by providing a series of paired statements that help the user narrow down the possible identification of an organism until a final identification is reached. Dichotomous keys are particularly useful for identifying and classifying organisms that are difficult to differentiate based on external characteristics.

On the other hand, genetics (DNA) is a more accurate way to classify organisms at the molecular level. DNA analysis allows scientists to compare the genetic information of different organisms and identify similarities and differences in their DNA sequences. By comparing the DNA sequences of different organisms, scientists can determine their evolutionary relationships and classify them into different groups. DNA analysis is particularly useful for identifying and classifying organisms that are difficult to differentiate based on external characteristics or for organisms that have evolved to look similar to each other.

In summary, both dichotomous keys and genetics (DNA) are useful tools for classifying organisms, but DNA analysis is generally considered to be a more accurate way to classify organisms as it provides a more detailed and precise understanding of their evolutionary relationships.
