Data Analysis:

Part 1:

| Days | No Fertilizer (cm) | Chemical Fertilizer (cm) | Organic Fertilizer (cm) |

|------|--------------------|--------------------------|-------------------------|

| 1    | 0                  | 0                        | 0                       |

| 2    | 0                  | 0                        | 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.

The process of Glycolysis is a catabolic process  in which two molecules glucose goes through a ten- step pathway and yield two molecules of pyruvate . It is a major part of carbohydrate metabolism .

Mechanism Of Glycolysis

The glycolysis is also known as EMP pathway and it is involved in both aerobic and anaerobic conditions .There are two phases in the mechanism of glycolysis in which 5 reactions takes place in each phase and the process of glycolysis takes place in cytosol

Preparatory phase refers to the  generation of two molecules of  glyceraldehyde 3-phosphate from one molecule of glucose which further goes into the payoff phase . In this phase two molecules of ATP are used and two regulatory enzymes were involved in this reaction .

Payoff phase refers to the further break down of two molecules of glyceraldehyde3-phosphate to two molecules of pyruvate . In this phase four molecules of ATP and two molecules of NADH are generated . In this phase only one regulatory enzyme is involved which is the breakdown of PEP to pyruvate  .

Both the phases of glycolysis takes place in the cytoplasm and there are  three enzymes that involved in regulating the glycolytic pathway .This process is also known as the catabolic process .

Eubacteria and Archaebacteria are the two Kingdoms are nearly the same. The correct option is C.

Eubacteria are prokaryotic microbes that consist of a single cell that lacks a nucleus and contains DNA in the form of a single circular chromosome.

Eubacteria are gram-negative or gram-positive bacteria with economic, agricultural, and medical significance. E. coli, Lactobacilli, and Azospirillum are among them.

Archaebacteria are referred to as ancient bacteria, whilst the eubacteria are referred to as true bacteria.

Archaebacteria, unlike eubacteria, can survive in harsh environments.

The resemblances are that archaea and eubacteria are both prokaryotes, which are single-celled organisms without a nucleus or organelles.

Thus, the correct option is C.

Biomes are determined by their climate which is determined by percipitation and temperature

Explanation:

There are two main factors when scientists define a biome. One is the climate or the long-time average weather of a region. The other is the specific plants and animals in an area. The organisms in a biome often adapt to their environment. There are seven types of biomes based on these factors.

Answer:

Meiosis

Explanation:

The statement that a certain amount of kinetic energy is required to break the bonds between atoms and make a chemical reaction go is not entirely accurate.

The rephrased statement is:

For a chemical reaction to occur, a minimum amount of energy, called the activation energy, is required to break the bonds between atoms in the reactant molecules, and the likelihood of a reaction occurring increases with the number of molecules with sufficient energy to overcome the activation barrier."

A chemical bond is a strong attraction between atoms or ions that allows molecules and crystals to form. Ionic bonds and covalent bonds both form when two oppositely charged ions interact electrostatically.

For a chemical reaction to occur, a minimum amount of energy, called activation energy, is required to break the bonds between atoms in the reactant molecules. This activation energy can come from a variety of sources, including heat, light, or catalysts, and it is often provided by the thermal energy of the surroundings.

However, it is not true that if the molecules do not have at least that energy, then there will be no reaction within the substance at all. In reality, there will always be some molecules with enough energy to undergo a reaction, even at lower temperatures, due to the statistical distribution of kinetic energies among molecules.

Once alcohol enters the bloodstream, it can quickly cross the blood-brain barrier and affect the brain and nervous system. The effects of alcohol on the brain depend on the amount and rate of consumption, and can range from mild impairment of judgment and coordination to more severe effects such as loss of consciousness and even death in extreme cases.

Chronic alcohol use can also lead to long-term changes in brain function and structure, including cognitive impairment and increased risk of developing certain neurological and psychiatric disorders.
