It is true i’ve had this on my test before
please give brainliest i wanna reach next rank
thanks!!
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
Answer: B. Vacuoles, cell membrane, nucleus, mitochondria
Explanation:
Cell walls only belong to plants, and chloroplasts also only belong to plants. Besides that everything else belongs to both, and that means that B is the only right answer. And I have a advise for you If they ask you a question like something like this In both plant and animal cells, the need to produce energy is carried out by the function of the: the answer is mitochondria
Hope it helps
