Artificial eutrophication is caused by humans through the discharge from farms, agricultural fields etc.

Eutrophication is basically defined as the process by which a water body or parts of a water body become enriched in nutrients and minerals like phosphorus and nitrogen. Due to this increase in the amount of nutrients, algal bloom in large amounts is observed.

Artificial eutrophication is caused by humans. The discharge from agricultural fields contains fertilizers. These fertilizers contain nutrients like phosphorus and nitrogen which increase the nutrition content in water and promote algal bloom. Another major cause of artificial eutrophication are the phosphates which are present in the dish washing liquids. Due to this, the amount of dissolved oxygen in the water decreases and this leads to the death of fishes living in it.

Natural gas only produces thermal oxides of nitrogen while coal produces both thermal and fuel oxides of nitrogen.

NO is a harmful gas that is produced as a byproduct of combustion and can lead to air pollution and respiratory issues when released into the atmosphere.

The higher the combustion temperature, the greater the amount of NO produced during coal combustion. In contrast, natural gas combustion does not produce as much NO because natural gas is primarily composed of methane and has a higher hydrogen-to-carbon ratio than coal, which results in less carbon dioxide and less NO production.

Natural gas combustion occurs at lower temperatures than coal combustion; hence, it produces less NO as a result. To summarize, the results of the study would be expected to show that natural gas combustion produces less NO than coal combustion, and this is attributed to the differences in the composition of coal and natural gas.

Answer:

#14. C and #15. A

Explanation:

In a glass of water, the most common ion found is the hydroxide ion (OH-) and the hydrogen ion (H+).

These ions are formed when water molecules dissociate through a process called self-ionization or autoionization.

In a glass of water, several ions can be found, originating from the dissociation of water molecules. The main ions present are hydrogen ions (H+) and hydroxide ions (OH-), resulting from the self-ionization of water.

Water molecules can break apart spontaneously into equal concentrations of H+ and OH- ions through a process called autoionization. This occurs when a water molecule donates a proton (H+) to another water molecule, forming H3O+ (hydronium ion) and OH-.

Additionally, other ions might be present in a glass of water depending on its source. For example, tap water can contain various dissolved ions like calcium (Ca2+), magnesium (Mg2+), sodium (Na+), chloride (Cl-), and bicarbonate (HCO3-). These ions come from minerals and other substances present in the water source, such as groundwater or surface water.

It's worth noting that the specific ion composition of water can vary depending on factors like location, treatment processes, and water source. However, the fundamental ions present in water are H+ and OH- resulting from the autoionization of water molecules.

Yes the Clements successional theory has been subjected to peer review and publication

Yes, the Clements successional theory been subjected to peer review and publication.

Plant succession was characterised by Clements as a developmental process that, during the course of a community, it went through a well-defined series of stages that, in the end, resulted in a mature community, also known as the climax community. The climatic conditions that determined the climax community's existence manifested themselves in the form of an indicator and an expression of that community.

His hypothesis of community formation, sometimes known as plant succession, is what brought Clements the most fame. Even after World War II, Clements' organicism and physiological perspective were still around, albeit in a watered-down version, despite the fact that it was extensively discredited by later ecologists.

A cell with 10 chromosomes undergoing mitosis and cytokinesis will produce two daughter cells with the same number of chromosomes as the parent cell.

During mitosis, the parent cell undergoes a series of steps to divide its chromosomes into two identical sets, which are then distributed to the two daughter cells during cytokinesis. Each daughter cell receives one set of chromosomes, resulting in two genetically identical cells.

Therefore, the two daughter cells produced by this process will each contain 10 chromosomes, the same number as the parent cell.

Mitosis is a process of cell division that occurs in somatic cells, resulting in the production of two daughter cells that are genetically identical to the parent cell.

During mitosis, the cell undergoes a series of steps that separate the chromosomes into two identical sets, which are then distributed to the two daughter cells during cytokinesis.

In the case of a cell with 10 chromosomes undergoing mitosis and cytokinesis, the cell would first duplicate its chromosomes during the S phase of the cell cycle, resulting in 20 chromosomes.

Then, during mitosis, the chromosomes would be separated into two identical sets, each containing 10 chromosomes. Finally, the cell would undergo cytokinesis, dividing into two separate daughter cells, each with the same number of chromosomes as the parent cell.

Photosynthesis and cellular respiration are essential processes that occur in living organisms. In this response, we will address several questions related to these processes and their experimental techniques.

5. Acetone is used as a blank for the chlorophyll absorption spectrum because it does not absorb light at the wavelengths of interest in the experiment. By using acetone as a blank, any absorbance detected at the wavelengths of interest can be attributed to the chlorophyll and not to other compounds that may be present in the sample.

6. The rate of photosynthesis is affected by the intensity of light because the process of photosynthesis requires energy from light to drive the chemical reactions that convert carbon dioxide and water into glucose and oxygen. As the intensity of light increases, the rate of photosynthesis also increases until a certain point is reached, beyond which the rate remains constant. This point is called the saturation point, and it is determined by the availability of carbon dioxide, water, and other factors such as temperature and the concentration of chlorophyll.

1. Cellular respiration is a metabolic process that converts glucose and oxygen into carbon dioxide, water, and ATP. The overall equation for cellular respiration is:

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

Fermentation is an anaerobic process that converts glucose into lactic acid or ethanol and carbon dioxide. The overall equation for fermentation is:

C6H12O6 → 2C2H5OH + 2CO2 (ethanol fermentation)

or

C6H12O6 → 2C3H6O3 (lactic acid fermentation)

2. To determine the hourly rate of CO2 production, the amount of CO2 produced over a certain time period is divided by the length of that time period. For example, if 50 mL of CO2 is produced in a 2-hour period, the hourly rate of CO2 production would be 25 mL/hour.

3. The difference in CO2 production between glucose and galactose in the yeast fermentation lab may be due to the different ways in which these sugars are metabolized by yeast. While both glucose and galactose are monosaccharides with the same chemical formula, they are metabolized by different pathways in yeast. Glucose is metabolized through the Embden-Meyerhof pathway, while galactose is metabolized through the Leloir pathway. The Leloir pathway requires an additional step compared to the Embden-Meyerhof pathway, which may result in a slower rate of fermentation and less CO2 production.

4. In the fermentation reaction, glucose is split into two molecules of pyruvate, which are then converted into either lactic acid or ethanol and carbon dioxide. It is the conversion of pyruvate into lactic acid or ethanol and CO2 that produces the CO2 in the fermentation reaction.
