Answer:
550 milliliters of water is needed.
Explanation:
the student will need 550 milliliters of water for completing the whole experiment. 250 milliliters of water is needed for boiling purpose while on the other hand, 100 milliliters of water is needed for one process which can be repeated three times so the process needs 300 milliliters of water so by combining the 250 milliliters and 300 550 milliliters of water we get 550 milliliters of water for the whole experiment so we can say that the student needs 550 milliliters of water for the experiment.
Answer:
Ferns do not have true leaves as many plants do, but structures called fronds. These fronds are split down into leaflets called pinnae. These fronds are green and the fern gets its food via photosynthesis. Ferns reproduce by spores in an alternating generations.
Explanation:
i studied ferns for years
The scratch test.
The scratch test is used by scientists and people who study rocks and minerals to determine the strength of the rock. They have the scratchers numbered one through ten and scratch the rock or mineral until the scratcher makes a mark in the mineral then they know the strength of the rock.

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
