Answer:
Most protists move with the help of flagella, pseudopods, or cilia. Some protists, like the one-celled amoeba and paramecium, feed on other organisms. Others, such as the one-celled euglena or the many-celled algae, make their food by photosynthesis. ... Theyuse pseudopods to move away from bright light or to trap food.
The binomial nomenclature system of classifying organisms was developed by <u>Linnaeus</u>.
Binomial nomenclature- Binomial nomenclature is a method of naming biological entities that consists of two terms: the first one designates the genus of the organism, and the second one designates the species.
Genus- Genus is the biological categorization that comes after family & species, consisting of isolated species that demonstrate exceptional differentiation or a group of structurally and phylogenetically related species (monotypic genus).
Species- A species is a group of organisms made up of similar individuals that are potential of interbreeding or gene exchange. The most fundamental unit of classification in biology is the species, which also serves as a taxonomic rank.

The two main variables in an experiment are the independent and dependent variable.
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.
A dependent variable is the variable being tested and measured in a scientific experiment.
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.
For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light is controlled by the scientist. This would be the independent variable. How the moth reacts to the different light levels (distance to light source) would be the dependent variable.
When results are plotted in graphs, the convention is to use the independent variable as the x-axis and the dependent variable as the y-axis.
