Rachael wants to test how sunlight impacts plant growth over time. She will add varying amounts of light to different sets of pl
Mrrafil [7]

Answer:

Independent variable: varying amounts of light

Dependent variable: plant growth

Explanation:

The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.

The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).

Answer:

Osteoclasts are the multinucleate bone cell that are responsible for absorbing bone tissue during healing and growth while osteoblasts are the cell responsbile for formation of new bones.

If there will be greater amount of osteoclasts than osteoblasts than the osteoclasts will allow calcium, present in bones to get dissolve which causes deformity of bones known as Osteoporosis (demineralization of the bones).

<em>Due to this the calcium level will increase in the kidney and can cause kidney stone as well.</em>
