What is the difference between independent and dependent variables

Biology
1 answer:
trasher [3.6K]4 years ago
4 0

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.

Question 3(Multiple Choice Worth 4 points)
salantis [7]

Answer:

Domains

Explanation:

Living organisms are divided into three domains:

Archaea

Eubacteria

Eukarya

Organisms are divided into these three domains based on genetic similarities or closeness. Archaea and Eubacteria are domains that consist of prokaryotes or prokaryotic cells.

Prokaryotes in the domain Archaea differ from those in Eubacteria because of certain characteristics like their ability to live in extreme environments and the absence of the peptiglycan in their cell walls.

Prokaryotes in the Eubacteria domain have peptidoglycan walls and RNA unique to them.

Organisms uner Eukarya, as the name suggests, have eukaryotic cells meaning the have an enclosed or membrane-bound nucleus.

nexus9112 [7]

Answer:

The answer is a) simple diffusion.

Explanation:

Osmosis is more similar to simple diffusion due to the fact that it doesn't require a protein or channel to facilitate its movement through the membrane. Also, it doesn't require any energy, but it does mostly depend on a chemical, or sometimes electrical, gradient.
