A group of scientists are studying the effects of different fertilizers on the growth of pea plants. They began their study with 10 pea plants. They gave each plant a different type of fertilizer and tracked their growth over a period of 2 months. What’s the independent variable in this experiment?

Answers

Answer 1

Answer: The answer is a type of fertilizer.

An independent variable is variable that is not affected in the experiment. It is what experimenter controls. On the other side, a dependent variable is called dependent because it depends on the independent variables. It is what is affected during the experiment.
In this case, the growth of pea plants depends on different types of fertilizer. So, the growth of pea plants is the dependent variable and different type of fertilizer is the independent variable.

Which is a part of the cell theory? cells come from pre-existing cells cells have a nucleus organisms with one cell must be seen with a microscope organisms must have more than one cell to live

Answers

A part of the cell theory is cells come from pre-existing cells. The correct option is A.

What is the cell theory?

The cell theory is the conclusion of many scientists. There are three postulates of the cell theory. They are: all organisms are made up of cells. New cells are made up of old cells, and the cell is the basic structural and functional unit of life.

The cell is the smallest and basic unit of life. All functions of the body are performed by cells. It contains a cell organelle that has different functions and structures.

A nucleus is present in the cell and microscopic organs must have a single cell, they are not a part of cell theory, this is more related to the organism, not cells.

Thus, the correct option is A. cells come from pre-existing cells.
