Answer:
Fish, water pH and the water itself
Explanation:
Fish affect the freshwater system since they live and excrete their waste in the water
pH levels of water should not be below 6 or above 8 for a healthy drink
Also, algae affects the freshwater system
Answer:
This question is incomplete; the question is asking to identify variables such as the DV, IV, Constants etc
Independent variable (IV): Type of flowers
Dependent variable (DV): Growth of flowers
Constants: the same amount of sunlight, same amount of water
Explanation:
The independent variable is the variable that an experimeter changes or manipulates deliberately in order to bring about an effect in another variable. In this experiment, the TYPE OF FLOWER on each soil is changed by Alex, hence, it is the independent variable.
Dependent variable is the variable that is being measured in the experiment. It is the variable that responds to the changes made to the independent variable. In this case, the dependent variable is the GROWTH OF THE FLOWERS measured.
Constansts or control variable is the variable that the experimenter keeps constant or unchanged throughout the experiment in order to maintain the outcome of the experiment. In this case, the constants are the same amount of light, same amount of water
Answer:
occurrence
Explanation:
Probability is a mathematical construction that determines the likelihood of occurrence or nonoccurrence of events that are subjected to chance factor. Thus the farmers are interested to know the probability of occurrence of rain before and after spraying. ... In this regard probability plays a great role
It allows us to determine not only how and why organisms have become the way they are, but also what processes are currently acting to modify or change them !
