How would you improve this experiment?
As a real-world application, how can this experiment be beneficial?
John had a science fair project that he needed to do. He wanted to test the effects that organic and chemical fertilizers had on plant growth. John predicted that the organic fertilizer would make the plants grow taller. He used three pots, three of the same type of seed, soil, organic fertilizer, chemical fertilizer, water, and a ruler. John put soil in the pots. He added chemical fertilizer to the first pot, organic fertilizer in the second pot, and no fertilizer in the third pot. He then planted one seed in each pot. John had to water the pots daily. He also checked for growth and took measurements for a period of 10 days. He measured the height of the plants.
Days No Fertilizer (cm) Chemical Fertilizer (cm) Organic Fertilizer (cm)

2 0 0 0

10 0.2 5.2 3.8
John made a data table to record his measurements.
After the 10th day, John observed that the plant with the chemical fertilizer grew the most.

Data Analysis:
Part 1:
| Days | No Fertilizer (cm) | Chemical Fertilizer (cm) | Organic Fertilizer (cm) |
|------|--------------------|--------------------------|-------------------------|
| 1 | 0 | 0 | 0 |
| 2 | 0 | 0 | 0 |
| 3 | 0 | 0 | 0 |
| 4 | 0 | 0 | 0 |
| 5 | 0 | 0.5 | 0 |
| 6 | 0 | 1.3 | 0 |
| 7 | 0 | 1.9 | 0.3 |
| 8 | 0 | 2.2 | 1.6 |
| 9 | 0 | 4.5 | 3.2 |
| 10 | 0.2 | 5.2 | 3.8 |
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.

Since plant matter generates heat as it decomposes, where would a fire be most likely to start in the piles of grass?
Answers
Answer:
In the middle of the pile of grass.
Explanation:
The fire would be most likely to start in the middle of the piles of grass if spontaneous combustion occurs because the heat doesn't easily move through the medium due to the insulating nature of grass. A pile of grass can catch fire due to spontaneous and quick combustion in the middle of piles of grass. So the fire starts in the middle of the pile of grass.

Which type of mutation occurs only in gametes?
germline mutation
somatic mutation
point mutation
frameshift mutation
Answers
Answer:
Germline mutation
Explanation:
A germline mutation is a genetic change produced in the gametic-germline cells (i.e., male and female gametocytes). The mutations in the germline are inherited in the next generation, while changes in somatic cells are not inherited. Moreover, the germline mutations may occur either before the fertilization or during embryonic development (zygote morula, blastula and gastrula). This type of mutation may be induced by both endogenous (e.g., oxidative DNA damage) and exogenous (e.g., exposure to UV light) factors.
The type of mutation that occurs in gametes only is : ( A ) Germline mutation
Germline mutation is a type of mutation that occurs in the gametocytes ( male and female ) and is passed( inherited ) on to the offspring ( next generation ). while mutations occurring in somatic cells are not passed on to the next generation .
Germline mutation is induced by either endogenous factors or exogenous factors and this is because Germline mutations can occur before fertilization or after fertilization.
Hence we can conclude that the type of mutation that occurs in gametes only is Germline mutation.

How can histograms help you describe a population? Use the word bank above to help you explain your answer.
Answers
Answer: It shows the distribution of the population with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.
Explanation:
A histogram is a graphical representation of a variable using bars. In such a bar, its area is proportional to the frequency of the values represented. Thus, it shows the distribution of the population, or of the sample, with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.
In order to construct a histogram first we need to have a frequency table with all the information. On the abscissa axis (horizontal axis) the intervals are placed from smallest to largest. On the ordinate axis (vertical axis), the absolute frequencies of each of the intervals are represented. Then, the rectangular bars of equal width are drawn, and the height represents the absolute frequency. All bars touch the bars next to each other, unless an interval has zero frequency (the height of the bar will also be zero).
Thus, histograms are used to describe populations since they represent a variable and in what proportion of the population it is found.
The population can be given as the number of people living in a specific area. The histogram represents the population, with frequency as the function of the area.
What is a histogram?A histogram is the graphical representation of the data in the form of bars. The population is given as the number of people in an area.
