Hello. Your question is incomplete. However, when researching, I managed to find a question like yours and found that you forgot to mention that the question wants you to determine which is the best reference point in this scenario.

Answer:

The best point of reference is the starting position of the toy car.

Explanation:

To study the movement of the car it is necessary for Sudhi to establish a reference point, so that she can calculate all the variables associated with this movement. The best variable in this scenario is the starting position of the car, when it is still on the ramp. Thus, Sudhi needs to determine the distance between the car and the ground, that is, what the car's starting position is. She will be able to discover this when determining the height of the ramp.

C. Read the hypotheses below, and identify the
tiny-mole [99]

Answer:

Independent variable: Salinity/Salt concentration

Dependent variable: hatching rate

Explanation:

As rightly stated in this question, INDEPENDENT VARIABLE, in an experiment, is the variable that the experimenter changes or manipulates in order to bring about a measurable response while the DEPENDENT VARIABLE is the variable that the experimenter measures in an experiment. Dependent variable as the name implies is dependent on the independent variable.

In this question where an hypothesis was given as follows: "Hatching brine shrimp is related to salinity (how salty the water is), then the greater the salt concentration, the higher the hatching rate". The hypothesis relates the independent and dependent variables i.e. it tells us how the independent variable affects the dependent variable.

Hence, according to the hypothesis, it is telling us how a change in SALINITY OR SALT CONCENTRATION will affect HATCHING RATE. Therefore;

Independent variable: SALINITY/SALT CONCENTRATION

Dependent variable: HATCHING RATE
