Answer:
Hypothesis is ''With the increase of algae in the aquarium, fish population decreases''.
Explanation:
The main problem was that there is no need for 2 aquarium because there is no need for aquarium 1 which has no fish and aquarium 2 which has fishes but no algae. With the increase of algae in the aquarium, fish population decreases is the hypothesis for this experiment. Concentration of algae is the independent variable of the experiment because there is no effect on it in the experiment.
D) male
Most mammals use the X and Y system to determine sex.
Males have 1 X chromosome and 1 Y chromosome while females have 2 X chromosomes.
The question states that there are 2 different sex chromosomes, so this rabbit must be male.
The greenhouse effect that keeps the thermal excursion to a minimum and grants a warm temperature
Answer:
(3) completing a data table of expected results
Explanation:
Observation and research of the available literature about the process under study are some of the tasks done before experimentation. The data table of expected results is not to be made before any research.
Research and discussion on the basic information about the enzyme under study, the search of any experiments done on the same enzyme earlier gives insight about the enzyme. This is followed by making a hypothesis and setting the experiment to test the hypothesis.
Answer:
enzymes are biological moleucles that significantly speed up the rate of virtually all of the chemical reactions that take place within cells.
