When skin cells are damaged by ultraviolet radiation from the sun, they are replaced by new ones. Explain how this fact provides evidence that supports one or more parts of cell theory?

The cell theory states that:

1.  All living things are composed of cells (or cell products)

2.  The cell is the smallest unit of life

3.  Cells only arise from pre-existing cells

Explanation:

Cells removed from tissues can survive independently for short periods of time

Nothing smaller than a cell has been found to be able to live independently

Experiments by Francesco Redi and Louis Pasteur have demonstrated that cells cannot grow in sealed and sterile conditions

Movement:   Living things show movement, either externally or internally

Reproduction:   Living things produce offspring, either sexually or asexually

Sensitivity:   Living things can respond to and interact with the environment

Growth:   Living things can grow or change size / shape

Respiration:   Living things use substances from the environment to make energy

Excretion:   Living things exhibit the removal of wastes

Nutrition:   Living things exchange materials and gases with the environment

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
