Answer:
The periosteum is one source of precursor cells which develop into chondroblasts and osteoblasts that are essential to the healing of bone. Other sources of precursor cells are the bone marrow (when present), endosteum, small blood vessels, and fibroblasts.
Because it causes them to move, and so they weather that way. Buut the acid rain can leak into the rock and slowly break down the atoms, causing it to chemically weather faster. Also, just regular water/rain can wash away some covering sediment.
1) Mice not radio waved.
2) Radio
3) Strength of mice
4) Maybe inconclusive.
5) Improves strength
Explanation:
- Control Group - Mice not radio waved.
- Independent Variable - radio.
- Dependent Variable - Strength of mice.
- What should Bart's conclusion be? Maybe inconclusive.
- How could Bart's experiment be improved? Improves strength
Experimental setup
setup that is testing a hypothesis using a variable. In most cases only one variable should be tested at a time.
Control Setup
setup that is identical to the experimental setup, only it does not contain a variable.
Independent Variable
The one factor that is change by the person doing the experiment
Dependent Variable
The factor which is measured in the experiment
Constant
all the factor that stay the same in an experiment.
Cohesive. This means that the water is attracted to other particles of itself, so they stick and bead up.
