The theory regarding the transition occurring in a population in a country or a region.
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:
The three main types of lipids are - triglycerides, diglycerides, and steroids.
Explanation:
Lipids are organic compounds that are fatty acids or their derivatives. Lipids are insoluble in water but soluble in organic solvents (alcohol, ether). The three common lipids are triglycerides, diglycerides, and steroids.
An ester derived from glycerol and three fatty acids is a triglyceride. These are the main component of body fat in the vertebrates as well as the vegetable fat.
A Glyceride consisting of 2 fatty acid chains bonded to a glycerol molecule covalently through ester linkages is a diglyceride.
Biologically active organic compounds with four rings arranged in a specific molecular configuration are steroids.
Centrioles is only found in animal cells but not in plant cells.

True is the answer but i don't know why
