Answer:
<u>independent variable:</u> size of soccer ball
<u>dependent variable</u>: period of time the balls stay in the air
<u>control variable</u>: parts of the body used to juggle the ball
Explanation:
The independent variable is the manipulatable variable supplied into an experiment. It is a variable that directly affects the dependent variable.
The independent variable is the outcome variable. It is the variable that is primarily measured from experiments whose value depends on the value of the independent variable.
The control variables are those that are kept constant throughout the course of experiments. In other words, they do not directly affect experimental outcomes.
Hence, in the illustration;
<u>independent variable</u>: size of soccer ball
<u>dependent variable</u>: period of time the balls stay in the air
<u>control variable</u>: parts of the body used to juggle the ball

Answer:
The correct answer will be option- adhere to cell surfaces.
Explanation:
The bacterial fimbriae are the cellular appendages which help the bacteria to attach to a substratum. This attachment property of the fimbriae is due to the presence of a protein called adhesins.
The fimbriae are also known as the attachment pilus of the bacteria which are thinner than a flagellum. The bacteria posses many fimbriae to adhere to the surface like to receptors, another bacteria or any other substratum.
Thus, option- adhere to cell surfaces is the correct answer.
