Scientific Method
What is the main purpose of the Scientific Method?
To answer scientific questions using observation, investigation and evidence.
According to cell theory, all new cells come from these.
what are existing cells
What is DNA, genes, and chromosomes?
DNA is made up of chromosomes, which produce genes
True or False? Prokaryotic cells do not have a nucleus
True
What type of cell division produces two identical daughter cells for growth and repair?
What is meiosis
What is a testable explanation for an observation that scientists investigate through experiments?
What is a hypothesis
Which theory states that all living things are made up of cells
What is the Cell Theory
What type of cell has a nucleus that contains its DNA?
What are eukaryotic cells
This is a well-supported scientific explanation backed by extensive evidence, while a hypothesis is a testable explanation for a specific observation.
What is a scientific theory
What are the three main principles of Cell Theory?
1. All living things are made of cells
2. Cells are the basic units of life
3. All cells come from pre-existing cells
Define and explain what Chromosomes are
Chromosomes are made of DNA, that contain genes
(more to be added)
What structures inside eukaryotic cells perform specialized jobs, such as producing energy and making proteins?
What are organelles
What type of cell division produces four genetically different haploid cells, each containing half the number of chromosomes as the original cell?
Name the 7 steps of the Scientific Method in the correct order.
1. Ask a Question to be researched
2. Do background research and Observe
3. Form a Hypothesis to test
4. Conduct an experiment
5. Analyze the results
6. Draw a conclusion
7. Communicate the results
Which molecule stores genetic information?
What is DNA
These 2 groups of organisms are made of prokaryotic cells.
what are bacteria and viruses
What happens when cell division goes out of control?
Cells grow too quickly which causes cancer.
After analyzing the results of an experiment, a scientist discovers that the data do not support the original hypothesis. What should the scientist do next?
What is revise the hypothesis and conduct further experiments?
This theory explains how traits are passed from parents to offspring through units of heredity that contain genetic information.
What is gene theory
Name the order of stages of cell division of Eukaryotic cells.
Prophase
Metaphase
Anaphase
Telophase
