The male gamete, sperm, is a smaller, mobile cell that meets up with the much larger and less mobile female gamete, egg or ova. Both sperm and egg are only haploid cells. They only carry half of the chromosomes needed.

I have never heard of the four phases of research, but I know that the scientific method can be summarized in four steps.
1. Observe something in nature.
2. Make a hypothesis (prediction) based on that observation.
3. Design and undergo and experiment to test the validity of your hypothesis.
4. Draw a conclusion about your hypothesis based on the results of your experiment.
Saturated fats are solid at room temperature, while unsaturated fats are liquid at room temperature. This is because saturated and unsaturated fats differ in their chemical structures.
Saturated fats have no double bonds between the molecules , which means there are no gaps and the fat is saturated with hydrogen molecules. Unsaturated fats have double bonds, which break up the chain of hydrogen molecules and create gaps, allowing the fats to liquefy at room temperature.
Saturated fats are found mainly in animal food such as meat and dairy products, while unsaturated fats are found in plant food and fish.
