Answer:
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.

c) Overall, the average surface temperature of the earth is increasing.
d) None of the above are true.
Answer:
the answer is a
Explanation:

Answer:
210
Explanation:
Frequency of dominant allele is represented by "p"
and frequency of recessive allele is represented by "q"
Given
Thus,
As per Hardy Weinberg's second equation of equilibrium -
Substituting the given values in above equation, we get -
So the total number of heterozygous individual is equal to
B. Solar energy
C. Electron energy
D. Chemical energy
Answer:
D. Chemical energy is the correct answer.
Explanation:
Chemical energy form is energy stored in at the end of photosynthesis.
At the end of photosynthesis energy from the sunlight is stored in the chemical energy.
Photosynthesis is a process through which organisms that contain chlorophyll pigment converts sunlight energy into chemical energy.
Plants produce food by photosynthesis utilizing light energy and chemical energy is that stores energy.
