Answer:
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
Explanation:
Answer and explanation;
The steps followed in an experiment include;
-Observation; this involves
taking note of something such as a curious phenomenon worth further thought and investigation
-Research; it involves forming a question so as to find out more about the natural phenomenon observed.
-Hypothesis, this is an informed guess as to the possible answer of the question.Its purpose is not to arrive at the perfect answer to the question but to provide a direction to further scientific investigation.
-Experiment, the hypothesis formed must be tested by conducting a well designed and controlled experiment. Its is an important step as it proves whether the hypothesis is correct or wrong.
-Analysis; it entails taking down the results and analyzing it together with the data and suing it to draw conclusion regarding the strength of the hypothesis.
-Conclusion; From the analysis a conclusion about the hypothesis can be drawn, explaining why the phenomenon occurs.
-Publish; the results may then be published as a reference and for future use and comparison.
The steps followed in an experiment are as follows: Observation, Research, Hypothesis, Experiment, Analysis, Conclusion, and Publication.
1. Observation: This involves noticing and identifying a curious phenomenon or event that requires further investigation.
2. Research: Conduct background research to gather existing knowledge and information related to the observed phenomenon. Formulate a question or hypothesis based on this research.
3. Hypothesis: Develop an informed guess or prediction about the possible answer to the research question. The hypothesis provides a direction for the experiment and serves as a tentative explanation for the observed phenomenon.
4. Experiment: Design and conduct a well-controlled experiment to test the hypothesis. Plan the procedures, identify variables, establish control groups, and collect data through systematic observations and measurements.
5. Analysis: Analyze the collected data using statistical or analytical methods. Look for patterns, trends, and relationships in the data to determine whether the hypothesis is supported or refuted.
6. Conclusion: Based on the analysis of the data, draw conclusions about the hypothesis. Explain the findings and discuss their implications in relation to the original research question. Assess the strength of the hypothesis and its alignment with the observed data.
7. Publication: Share the results of the experiment by publishing them in a scientific journal or presenting them at conferences. This allows other researchers to review, replicate, and build upon the findings, contributing to the scientific knowledge and understanding of the phenomenon.

Answer:
Multicellularity
Autotrophy
Membrane-bound Nuclei
Explanation:
This kingdom of plantae comprises of the more familiar green plants. They are multicellular organisms which contain the green light-trapping pigment called chlorophyll. They make their own food from carbon dioxide, water and mineral salts using sunlight energy, a process called photosynthesis. Thus plants are said to autotrophic.
