The change to the investigation that would remove the source of the error noticed by the scientist is to test a fourth group, in which the participants do not receive the mineral supplement (option A).

A controlled experiment is an experiment designed to replicate the main experiment in every way, except in respect of the one variable that is being tested, so as isolate the effect of that variable.

In other words, a control is introduced in the experimentation process. A control is group of test subjects left untreated or unexposed to the independent variable.

According to this question, a company is testing the effect of a mineral supplement on common cold. The experimental procedure is okay except that they didn't include a fourth group, which will serve as the control.

Part 2: [Insert a line graph representing the height of each plant over the ten days. Title the graph "Plant Growth Over 10 Days."]

Conclusion:

The analysis of the data shows that the chemical fertilizer worked best, as the plant treated with chemical fertilizer grew to 5.2 cm in height, while the organic fertilizer plant grew to 3.8 cm. The plant with no fertilizer did not grow well, only reaching 0.2 cm in height over the ten days.

John's hypothesis that the organic fertilizer would make the plants grow taller was incorrect. The chemical fertilizer had a greater impact on plant growth than the organic fertilizer. To further test this investigation, John could use a wider variety of plants, different types or concentrations of fertilizers, or extend the duration of the experiment.

Questions:

1. A scientific experiment is reliable when it is:

  - **Replicable**: The experiment can be reproduced by other researchers with the same results.

  - **Controlled**: Variables are carefully controlled to reduce the impact of external factors on the experiment's outcome.

  - **Valid**: The experiment measures what it is intended to measure, and the results accurately reflect the effect of the variables being tested.

2. Using peer-reviewed evidence during a scientific investigation is crucial because:

  - It ensures the information is accurate and reliable, as it has been reviewed and approved by experts in the field.

  - It helps maintain high standards of research and reduces the likelihood of using incorrect or misleading information.

  - It promotes the sharing of knowledge among researchers and encourages collaboration, which can lead to more reliable and effective scientific investigations.

Conclusion Questions:

John's hypothesis was incorrect because the data showed that the chemical fertilizer made the plants grow taller than the organic fertilizer.

Based on the data in the table, the chemical fertilizer worked the best, as it led to the greatest increase in plant height (5.2 cm) after ten days.

The plant that did not grow well was the one with no fertilizer, as it only reached 0.2 cm in height after ten days.

Analysis Questions:

To improve this experiment, John could:

  - Test different types or concentrations of fertilizers to see how they affect plant growth.

  - Use a larger sample size of plants for each fertilizer type to account for any variability within each group.

  - Extend the duration of the experiment to observe the long-term effects of the fertilizers on plant growth.

This experiment can be beneficial in real-world applications by helping farmers, gardeners, and agricultural companies determine which type of fertilizer is most effective for promoting plant growth. By understanding the impact of chemical and organic fertilizers on plant growth, they can make informed decisions about the best fertilization practices for their crops and gardens.

Plant diseases are a significant threat to food security in Ghana, as they can cause significant damage to crops and reduce yields. The country heavily relies on agriculture for food and income, making it vulnerable to the impact of plant diseases on its crops.

One example of a plant disease that has affected food security in Ghana is the cassava mosaic disease, which has devastated cassava crops in several regions. Cassava is a staple food in Ghana, and its loss can have a significant impact on food security and income generation for farmers.

Other plant diseases that affect crops in Ghana include the maize streak virus, bacterial wilt, and black pod disease in cocoa. These diseases can lead to significant crop losses, reducing the availability of food and increasing the prices of agricultural products, which affects food access for low-income households.

Furthermore, the spread of plant diseases can also limit trade and exports, affecting the economy of Ghana. Plant diseases can limit the ability of farmers to meet the demand for crops, which can result in food scarcity and economic hardship.

Ghana has developed several initiatives aimed at reducing the incidence and impact of plant diseases, including research, education, and training programs. These initiatives aim to improve crop management practices, promote disease-resistant crop varieties, and increase the capacity of farmers to recognize and manage plant diseases.

In conclusion, plant diseases pose a significant threat to food security in Ghana, and the country needs to develop strategies to mitigate their impact. Investing in research and education programs, promoting disease-resistant crop varieties, and improving crop management practices are all essential steps towards ensuring food security in Ghana.

The three human activities that have a negative impact on the biodiversity within Amazon rainforests are captive breeding of organisms, introduction of invasive species and restoration of degraded land.

The unique biodiversity of the Amazon rain forest has been threatened by deforestation caused by clear-cutting forests for hardwood timber, and to provide pastureland for cattle and crop farms.

Biodiversity loss from habitat destruction is often driven by land grabbing and industrialized agricultural expansion, mining, logging, and large-scale infrastructure development, usually through deforestation.

Insulin is a hormone produced by the pancreas that regulates blood sugar levels in the body. After a meal, especially one that is high in carbohydrates, the body releases insulin to help move glucose from the bloodstream into the cells where it can be used for energy or stored for later use.

During the day, when people are more active and consuming food, their insulin levels tend to be higher in response to the meals they eat. This increase in insulin can cause blood sugar levels to drop after a few hours, which can lead to feelings of hunger and the desire to eat again.

At night, when people are typically less active and consuming less food, their insulin levels tend to be lower. Without the constant intake of food and insulin, blood sugar levels remain more stable throughout the night and do not drop as quickly as during the day. As a result, people may not feel as hungry at night and may be able to go longer periods of time without eating.

Therefore, the fluctuation in insulin levels during the day versus night can help explain why people tend to feel hungry a few hours after a daytime meal but not so quickly at night.

The Gibbs free energy available to do work for the reaction is approximately -15,427.20 kJ, rounded to two decimal places.

To calculate the Gibbs free energy (ΔG) available to do work for the given reaction, we need to use the formula:

ΔG = -nFΔE

where ΔE is the potential difference, n is the number of electrons transferred, and F is the Faraday constant (96.5 kJ/(mol e- × V)).

First, let's calculate the ΔE for the reaction by subtracting the reduction potential of the anode (NH4+ to NO2-) from the reduction potential of the cathode (O2 to H2O):

ΔE = E(cathode) - E(anode)

= (+0.82 V) - (+0.34 V)

= +0.48 V

Next, we need to balance the full reaction to determine the number of electrons transferred (n) when 440 moles of NH4+ are oxidized. The balanced equation is as follows:

8NH4+ + 6O2 -> 8H2O + 6NO3- + 16H+

From the balanced equation, we can see that for every 8 moles of NH4+ oxidized, 6 moles of electrons are transferred.

So, the number of electrons transferred (n) when 440 moles of NH4+ are oxidized can be calculated as:

n = (6 mol e- / 8 mol NH4+) × 440 mol NH4+

= 330 mol e-

Therefore, when 440 moles of NH4+ are oxidized, 330 moles of electrons are transferred.

Now, let's substitute the values into the equation:

ΔG = -nFΔE

= -(330 mol e-) × (96.5 kJ/(mol e- × V)) × (+0.48 V)

Calculating this expression, we find:

ΔG ≈ -15,427.20 kJ
