What is the difference between independent and dependent variables
trasher [3.6K]

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.

The secondary structure of proteins results because of _____ bonding between molecules in the protein molecules' backbone.
topjm [15]

Answer:

Hydrogen bonding

Explanation:

The newly synthesised proteins as a result of the process of translation are linear structures formed by linear arrangement of amino acids.

The linear structure of a protein is known as the primary structure which changes its conformation and take the shape of either the helix or the pleated sheet. This helical or pleated sheet structure is known as a secondary structure.

The secondary structure is formed due to the bond formed between the hydrogen of the carbonyl group and the amino group which form the backbone of the protein structure. The hydrogen bond causes the linear polypeptide to form spiral helical or bend pleated sheet.

Thus, Hydrogen bonding is the correct answer.
