Explanation:

Long answer: The scientific method is a systematic approach used by scientists to investigate and understand natural phenomena. It involves a series of steps designed to ensure that observations are accurate, experiments are well-controlled, and conclusions are valid. Here are the basic steps of the scientific method:

Observation: Begin by making observations about a specific phenomenon or problem. This could involve noticing something interesting, unusual, or puzzling in the natural world.

Research: Conduct background research to gather information and knowledge about the topic. This helps you understand what is already known and identify gaps in knowledge.

Hypothesis: Formulate a testable hypothesis, which is a proposed explanation for the observed phenomenon. A good hypothesis should be specific, clear, and capable of being tested through experimentation.

Experimentation: Design and conduct experiments to test your hypothesis. This involves manipulating variables, collecting data, and making careful observations. Experiments should be well-controlled to ensure that the results are reliable.

Data Collection: Collect and record data from your experiments. This may involve measurements, observations, or other forms of data depending on the nature of your research.

Analysis: Analyze the data you collected to determine if it supports or contradicts your hypothesis. Use statistical methods and tools to draw meaningful conclusions from the data.

Conclusion: Based on your analysis, draw a conclusion about whether your hypothesis is supported or not. If the results do not support your hypothesis, consider alternative explanations and further research.

Communicate: Share your findings with the scientific community and the public. This can be done through research papers, presentations, conferences, and other forms of communication.

Peer Review: Submit your work to scientific journals for peer review, where experts in the field evaluate the validity and quality of your research.

Repeat and Refine: Science is an ongoing process. If your hypothesis is supported, you may want to conduct additional experiments to further validate your findings. If it's not supported, you might refine your hypothesis, design new experiments, and continue investigating.

It's important to note that while these steps provide a general framework for the scientific method, the process is not always linear or strictly sequential. Scientists often go back and forth between steps as they refine their hypotheses, design experiments, and analyze results. The scientific method is a dynamic process that encourages curiosity, critical thinking, and a willingness to revise and expand our understanding of the natural world.

Short answer:

Observe: Notice something interesting or puzzling in the world.

Research: Gather information about the topic.

Hypothesize: Propose a testable explanation for what you observed.

Experiment: Design and conduct controlled experiments.

Collect Data: Measure and record information from your experiments.

Analyze: Study the data to draw conclusions.

Conclude: Determine if your hypothesis is supported by the data.

Communicate: Share your findings with others.

Refine: If needed, revise your hypothesis and repeat the process.

Remember, the scientific method is a flexible guide that helps scientists explore and understand the natural world.

Ifan animal's heart has three chambers and it lays amniotic eggs, it should be a reptile(e.g. pythons and monitor lizards). However, through amniotic egg, a protectiveadaptive sac inside the egg, it os useful for reptiles, amphibians, birds andmammals.

Ok so in this experiment what we want to find is the catalyst for the reaction. Our original reaction is the following. A + B --> C, therefore to find which of the unknown substances (X, Y, and Z) is the catalyst reaction we simply have to do the following:

A + B + X --> C

A + B + Y --> C

A + B + Z --> C

The reaction that produces C much faster than our original reaction A + B --> C will be our catalyst. The reason being that one of the substances will increase the rate of the chemical reaction.

I hope it helps, Regards.

Prepare three test tubes containing reactant A.  Prepare three test tubes containing reactant B.  Add one test tube of reactant B and one unknown to one test tube of reactant A. Repeat for the other two unknowns. Time the reaction until bubbling stops. The unknown that causes the reaction to occur the quickest is the catalyst.

1. Answer;

Lines of latitudes  

Lines on a map that run parallel to the equator are known as lines of latitude.

Explanation;

• Lines of latitudes are imaginary lines that run from east to west and measure north-south position between the poles.  
• Lines of latitudes are parallel to each other. The equator is zero degrees, while the North Pole is 90 degrees north and the South Pole is 90 degrees south.  
• Lines of longitudes or meridians on the other hand are imaginary lines that run between the North and South poles. They measure east-west position.

2. Answer;

B. astrophysics and planetary science

The two sub-specialties of astronomy are astrophysics and planetary science.

Explanation;

• Astronomy is a science that studies objects beyond the earth's atmosphere, such as planets, stars, asteroids, galaxies; and the properties and relationships of those celestial bodies.  
• Astrophysics involves the application of physics to understand astronomy. It involves the study of actual physical processes taking place in the universe, such as how they operate, etc
• Planetary science is the scientific study of planets, such as the earth and other planets in our solar system, moons, and planetary systems and the processes that form from them.

3. Answer;

D. a measure of gravitational force on an object.

Explanation;

• The weight of an object refers to the measure of the force exerted by gravity on the object. Weight will therefore depend on the gravitational force on a surface, and will vary from one place to another, such that the weight of an object on earth surface will be different on the moon’s surface.
• Weight is measured using a spring balance and is measured in Newton (N).

4. Answer;

D. The factor that's changed by the experimenter and impacts the dependent variable

Explanation;

• An independent variable is the variable that is changed or controlled by the experimenter in a scientific experiment to test the effects on the dependent variable.
• A dependent variable on the other hand is the variable being tested and measured in a scientific experiment. Dependent variable in an experiment changes from the manipulation of the independent variable.
• As the experimenter manipulates or varies the independent variable, the effect seen on the dependent variable is observed and recorded.

5. Answer;

B. Amount of silica it contains

Magma is classified as basaltic, andesitic, or rhyolitic based on the amount of silica it contains.

Explanation;

• Magma is defined as a molten and semi-molten mixture that is found under the surface of the Earth. Intrusive igneous rocks are formed from the magma that cools and solidifies within the earth’s crust, surrounded by an already existing rock.  
• Silica (SiO2) is the primary oxide present in magmatic rocks and serves as the basis of classifying magmatic rocks broadly.  

6. Answer;

Metallic bond

A metallic bond allows metals to conduct electricity.

Explanation;

• Metallic bonds are types of bonds or forces of attraction that occurs between the positive ions of metal and valence electrons known as sea of electrons that are constantly in motion around the positive ions.  
• The metal positive ions forms a lattice like-metallic structure that is held together by metallic bond. Metals conducts electricity as a result of mobile electrons which are free to move towards any direction.

7. Answer;

24  

There are 24 GPS satellites orbiting the Earth.

Explanation;

• The baseline satellite constellation contains 24 satellites which are positioned in six earth-centered orbital planes with four operation satellites and a spare satellite slot in each orbital plane.
• The 24 main GPS satellites orbit Earth every 12 hours, sending a synchronized signal from each individual satellite. A User will receive signals at slightly different times since the satellites are moving in different directions.

8. Answer;

B. dependent variable

Explanation;

• A dependent variable is the variable or a factor that is being tested and measured in a scientific experiment. An independent variable on the other hand is the variable or a factor that is changed or controlled by the experimenter in a scientific experiment to test the effects on the dependent variable.
• Dependent variable in an experiment changes from the manipulation of the independent variable.
• As the experimenter manipulates or varies the independent variable, the effect seen on the dependent variable is observed and recorded.
