What is the role of a control group in an experiment?

• The control group is used as a benchmark to measure how the other tested subjects do, ensuring that the results are due to the independent variable.

• The control group is the group that receives the treatment being tested.

• The control group is used to manipulate the independent variable in the experiment.

• The control group is the group that is not observed during the experiment.

What is photosynthesis?

• Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

• Photosynthesis is the method by which animals convert food into energy.

• Photosynthesis is the way in which plants absorb water from the soil.

• Photosynthesis is the process of respiration in plants.

What is the independent variable in an experiment?

• The factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

• The variable that remains constant throughout the experiment.

• The outcome that is measured in response to changes in the independent variable.

• The variable that is manipulated to observe its effect on the control group.

What is natural selection?

• Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

• Natural selection is the method by which species become extinct due to environmental changes.

• Natural selection is the phenomenon where all organisms have an equal chance of survival regardless of their traits.

• Natural selection is the practice of breeding organisms with desirable traits to enhance their survival.

What are homologous structures?

• Anatomical features in different species with similar structures and functions.

• Anatomical features in different species that have similar structures but different functions, indicating a common ancestry.

• Structures that perform the same function in different species but have different origins.

• Anatomical features that are identical in structure and function across different species.

What is the dependent variable in an experiment?

• The factor that is manipulated by the researcher.

• The factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

• The constant factor that remains unchanged throughout the experiment.

• The variable that is kept the same in all trials.

What is the function of ribosomes in a cell?

• Ribosomes are responsible for energy production in the cell.

• Ribosomes are involved in the breakdown of waste materials.

• Ribosomes are the cellular structures responsible for protein synthesis.

• Ribosomes help in the transportation of nutrients within the cell.

What is adaptive radiation?

• A process where organisms remain unchanged over time.

• A method of reproduction in plants.

• The process by which organisms diversify rapidly into a wide variety of forms to adapt to different environments.

• A technique used in genetic engineering.

What is the scientific method?

• A systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

• A random approach to solving problems without any structured methodology.

• A method used exclusively in laboratory settings for conducting experiments.

• A philosophical approach to understanding the universe without empirical evidence.

What is the difference between prokaryotic and eukaryotic cells?

• Prokaryotic cells have a nucleus and membrane-bound organelles, while eukaryotic cells lack these features.

• Prokaryotic cells are larger and more complex than eukaryotic cells.

• Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.

• Prokaryotic cells reproduce sexually, while eukaryotic cells reproduce asexually.
