A baseline measurement, or control variable, is important in scientific investigations because:

1. It allows you to compare the independent variable to the normal variable.

2. It allows you to test how effective the independent variable was.

3. It is easier to draw conclusions with a base line or control

4. In anything, a base line always allows you to formulate your goal.

A bad line measurement (aka control) is set up so that you can compare your results from each test against so it gives the values a meaning as it shows how they differ from eachother

Which value is being measured in the columns labeled fraction remaining and percentage remaining

ahrayia [7]

Question:

Which value is being measured in the columns labeled "Fraction remaining” and "Percentage remaining”?

years of decay
quantity of energy
number of stable atoms
amount of material that has not decayed

Answer:

"Amount of material that has not decayed" being measured in the columns labelled "Fraction remaining” and "Percentage remaining”

Explanation:

The table shown below having explains about the half life , the amount of sample in both fraction and percentage. The first column named half life elapsed tells us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.

The fraction remaining column gives the amount of sample that is left behind after the half life particular number of half life has completed. similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over $\frac{1}{16} th$ of the sample remained. In percentage it is 6.25%

which structure in the female reproductive system is comparable to the external reproductive organs in males

Oksi-84 [34.3K]

They are the same in that most of the reproductive organs of both sexes develop from similar embryonic tissue, meaning they are homologous. Both systems have gonads (male have testes and female have ovaries) that produce gametes (testes produce sperm and ovaries produce egg or ovum) and sex organs.
