Answer:
Meiosis
Explanation:
In a process of meiosis a sing cell divides twice to produce four daughter cells which contains half the amount of. genetic information These cells are sex cells. These four daughter cells consists of half the number of chromosomes of the parent so they are haploid. This is the reason in maple tree the chromosome decreased from 52 to 26.
The answer should be C, a plain.
Contour lines are used to indicate the height of the land in a map. The closer the contour lines are, the steeper the land will be, as the height of the land changes rapidly.
Therefore, if the contour lines are drawn far apart from each other, most likely the height of the land doesn't changes that much, it remains the same for a larger area, which means a plain should be the answer, as its height doesn't change as much as the other hills, cliff, or valley does.
Answer:
The correct answer is -
the independent variable - if fertilizer added or not,
the dependant variable - the height of the plant and
the standardized variable - 200ml water
Explanation:
In this study, the student wanted to see the effect of the fertilizer on the growth of the plant so the independent variable is the treatment of the fertilizer as manipulated or the independent variable is the factor which is affected or changed purposely during an experiment while other variables remain constant.
The dependent variable is the factor that is based or depends on the independent variable and measured to see the effect which is the height of the plants in this case.
The standardized or the control variable is the variable that remains constant throughout the experiment, 200 ml water treatment is the control variable in this experiment.
Im pretty sure its chemical energy because there also non renewable
