Answer:
Part 1. The amount of calcium is independent variable.
Explanation:
An independent variable is a variable in an experiment which is changed to see its effects on dependent variable.
In this experiment, to know about the causes of osteoporosis, the Ca level in blood or calcium intake in changed.
So the concentration of calcium will be independent variable.
Part 2.
The risk of bone fractures is could be changed with calcium.
Explanation:
In this experiment osteoporosis or risk of bone fracture is dependent variable.
Dependent variable are results of experiment which can be changed by independent variable.
As in experiment, Calcium concentration is independent variable.
So the risk of osteoporosis depends can change with calcium.
Answer:
Archaeologist.
Explanation:
I believe this is the only on of the four that deals with post-mortem study of bones, other than a forensic odontologist, who studies teeth and bitemarks, but not bones in general.
Answer:
Option C, Each subpopulation is linked to all other subpopulations by dispersal.
Explanation:
Each sub-population with in a metapopulation is not only connected by the dispersal distance travelled by an organism but also by the distance between the patches on which two sub population live. There are several other factors that limitise the concept of connection of subpopulation by dispersal factor and these vulnerable factors are – properties of terrain between the patches and its adverse affect on the dispersal behaviour of dispersing agent/species.
Hence, option C is correct.
