Answer:
1. Define a Question to Investigate
As scientists conduct their research, they make observations and collect data. The observations and data often lead them to ask why something is the way it is. Scientists pursue answers to these questions in order to continue with their research. Once scientists have a good question to investigate, they begin to think of ways to answer it.
2. Make Predictions
Based on their research and observations, scientists will often come up with a hypothesis. A hypothesis is a possible answer to a question. It is based on: their own observations, existing theories, and information they gather from other sources. Scientists use their hypothesis to make a prediction, a testable statement that describes what they think the outcome of an investigation will be.
3. Gather Data
Evidence is needed to test the prediction. There are several strategies for collecting evidence, or data. Scientists can gather their data by observing the natural world, performing an experiment in a laboratory, or by running a model. Scientists decide what strategy to use, often combining strategies. Then they plan a procedure and gather their data. They make sure the procedure can be repeated, so that other scientists can evaluate their findings.
4. Analyze the Data
Scientists organize their data in tables, graphs, or diagrams. If possible, they include relevant data from other sources. They look for patterns that show connections between important variables in the hypothesis they are testing.
5. Draw Conclusions
Based on whether or not their prediction came true, scientists can then decide whether the evidence clearly supports or does not support the hypothesis. If the results are not clear, they must rethink their procedure. If the results are clear, scientists write up their fi ndings and results to share with others. The conclusions they draw usually lead to new questions to pursue.
Answer:
The DNA molecule is a polymer of nucleotides. Each nucleotide is composed of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group. There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine). A DNA molecule is composed of two strands.

Saturated fatty acids are different to unsaturated fatty acids because they have no C=C double bonds.
<h3>What are the differences between saturated and unsaturated fatty acids?</h3>
- Saturated fatty acids do not have C=C double bonds, while in unsaturated fatty acids there is at least one C=C double bond in the fatty acid chain.
- Saturated fats are usually solid at room temperature and are derived from animal sources, whereas unsaturated fats are usually liquid at room temperature and are from plant sources.
- One must reduce the amount of saturated fat in their diet and consume more unsaturated fats like olives, seeds and nuts.
- Unsaturated fats can be monounsaturated (contains only C=C double bond) or polyunsaturated (contains two or more C=C double bonds).
