A scientist wanted to see if the number of eggs in a nest varied according to latitude. She decided to study a specific species of bird found in both tropical and temperate zone areas. One hundred nests were examined, in each of the 3 temperate zone areas (300 nests)and 3 tropical zones areas( 300 nests) for a total of 600 nests. In each case, the number of eggs were counted. In this investigation, what is the:. A. Question bejng asked?
B. Independent variable?
C. Dependent variable?
D. Constant?
E. Hypothesis?
F. Sample size?
G. Repeated measure?

A. Does the number of eggs in a nest of this bird species vary with the latitude of the area the bird lives in?

B. The latitude of the area

C. The number of eggs

D. The species of the bird

E. The number of the bird eggs in a nest in a temperate zone area will be greater than that of a tropical area.

F. 600 nests

G. The number of eggs

Explanation:

A. In the investigation, the scientist wanted to see if the number of eggs in a nest varied according to latitude, therefore, the question she will be seeking an answer to is: does the number of eggs in a nest of this bird species vary with the latitude of the area the bird lives in?

B. The independent variable is the variable that is not affected by the other variables being measured in an investigation. In the investigation by the scientist, the latitude of an area is the independent variable in that it is independent of changes in the other variable- the number o eggs- in the investigation.

c. The dependent variable is the variable that is affected by changes to the other variable in an investigation. The number of eggs is expected to vary according to latitude, is therefore, it is the dependent variable.

D. The constant is the factor that does not change during the experiment. The bird species is the constant as it does not change in the investigation.

E. A hypothesis is a specific statement predicting the result of an investigation or study.

In this study, the hypothesis could be: The number of the bird eggs in a nest in a temperate zone area will be greater than that of a tropical area.

F. The sample size gives the the total number of subjects,  individuals or observations in a study. In this case, the subjects are bird nests, and the sample size is 600 nests.

G. The number of eggs in all the nests were counted; therefore, it is the repeated measure.

the titanic would be the correct answer
