In an experiment, shara feeds her rat different brands of rat food (brands x, y, and z) each for 2 weeks and weighs the rat over several days during the period of each diet. what is the independent variable

The variables are defined as the factors in an experiment, which are liable to change. The variable can be dependent or independent. The Independent variable is a variable, which is unaffected by the changes in the other variables.

In this case, the brand of the food Shara feeds to the rats is independent factor, but it is changes in the system, so, it is an independent variable.

The effect on the weight of the rat is dependent on the brand of food they are consuming. So, the weight of rats is dependent variable.

sorry, but you do not have posted the diagram.

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
