It occurs during Anaphase II, Telophase II, and Cytokinesis, when the sister chromatids separate so that there is 1 allele per gamete.
Decrease as the more frogs there are the more flies will be eaten so that means the flies will decrease.Also if the flie population gets low enough the frog population would shrink too to balance it.
Independent variable: FERTILIZER.
This is the variable that you think affect your dependent variable and so you change it and use different types of it to confirm your prediction.
Dependent variable: COLOR.
That is the variable you are interested in.
Hypothesis: THE TYPE OF FERTILIZER USED IN CULTIVATING HYDRANGEA FLOWER AFFECT THEIR COLOR.
An hypothesis is a generalized statement which predicts the relationship between the variables you are examining.
Control group: THE GROUP THAT DID NOT GET ANY FERTILIZER
The control group is the group that does not receive any treatment.
Experimental groups: THE GROUPS THAT RECEIVED FERTILIZERS.
The experimental group is the group that receives treatment.
Constants: TYPES OF SOIL USED, MORNING SUNLIGHT, WATER AND THE NO OF DAY THE EXPERIMENT LAST.
The constants are the inputs into your experiment which you give to all the groups.
It is the scrotum, indeed.
