Drive the car and see if the mpg is accurate to what the manufacturers say it is. U might have to drive the car for a while but that’s the most accurate way to do it. Because all cars are different. Even if it’s the same model & brand.
Answer : The correct answer is - C) The left and right sides of the body are symmetrical.
Explanation -
Bilateral symmetry is a body plan of a life form, according to which the organism can be divided into two equal halves (right and left half) only when cut through central axis/midline of the body (also called saggital plane).
Example of bilaterally symmetrical organisms- insects like coackroach, butterfly.
Thus, option C) is the right answer.
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
The answer is A because the subject is responding to something that is going on outside of it, if that makes any sense :)
Hope this helps! Have a great day!
