<span>Epithelial tissue is densely packed cells that used most in the area where protection is needed. This cells mostly used in skin, some with more keratin which will increase their ability to protect. In bone, the main protective layer is calcium mineral which was deposited by osteocytes. Because this bone doesn't really need more epithelial cells. Bone tissue only needs a good vascularization and connective tissue to support it.

Answer:
The concentration of solution that contains a large amount of solute in the solvent could be described as concentrated
Explanation:
The concentration of solution that contains a large amount of solute in the solvent could not be described as diluted because i have just a little amount of solute.
The concentration of solution that contains a large amount of solute in the solvent could not be described as polar because polarity has a relation between molecules and its charges. Solvents or solutes are polar or not.
The concentration of solution that contains a large amount of solute in the solvent could not be described as unsaturated because unsaturated means that the mass of solvent is greater than solute.
Answer:
Independent variable: Adding/not adding soil.
Dependent variables: Does the plant grow? Amount of leaves, plant length.
Controlled variables: Type of plant used, amount of sunlight received, pot used for plant, amount of water given, temperature of soil, etc.
Explanation:
Independent variable: The thing that you want to change. To see if plants need soil to grow, you would need to either add or remove soil altogether.
Dependent variables: The thing that is being measured. By adding your independent variable, you should be able to answer certain questions.
Controlled variables: Things you want to keep the same for each experimental group. For example, if you used different plants, your results could be affected negatively as some plants might rely on soil less than others/grow at a slower or faster pace.
