called constants
The "control" factor. (The factor being tested is referred to as the "treatment" factor.)
A constant factor is one maintained unchanged throughout an experiment so that it does not affect the outcome. These are also referred to as controlled variables.
The ratio of value change of a portfolio to any paricular factor that drives the change
Resisting any change.
I don't think there is any beliefs of science that can't be changed, but we typically treat the scientific laws as certain.
"Rhesus factor" refers only to the presence or absence of the RhD antigen, symbolised by negative (absence) or positive (presence). Because it is caused by genetics, it cannot be changed by any artificial means, although it may change naturally - there are several documented cases of people changing bloodtype.
If you change the scale factor of a geometric figure by a factor "x", that is, keeping the new figure similar to the old one, the perimeter (which is also a linear measurement) will change by the SAME factor "x".Note that any area will change by a factor of x squared.
If you are asking how the perimeter of an object changes if the whole object is proportionally changed: The perimeter changes by the same factor as the change in proportion of the whole object. For example: given a square that is 2 units by 2 units, changed by a factor of four, the new size would be 8 units by 8 units. The original perimeter was 2+2+2+2=8. The new perimeter is 8+8+8+8=32. So, multiplying the original perimeter, 8, by the factor of proportional change, 4, we get 8x4=32. For any object, multiply the original perimeter by the factor of proportional change to arrive at the new perimeter.
controlled variable is the factor that leaved unchanged to investigate any only one factor that has been changed in the other experiment and the effect of not altering this factor.
