Answer:
C-None of these are found in an observational study
Explanation:
(A.) controlled variables are a part of what's found in a controlled experiment. (B.) manipulated variables are a part of what's found in a controlled experiment. (C.) Answer choice A. or Controlled variables, Answer choice B. or Manipulated variables, and Answer choice D. or Control groups are a part of what's found in a controlled experiment. (D.) Control groups are a part of what's found in a controlled experiment. Therefor this only leaves one answer and that answer is Like I said C-None of these are found in an observational study.

Answer: different structures and different functions
Explanation:
Plasma membrane is also name as cell membrane. It is a structure that surrounds the cell from the outside. it controls what enters and leaves the cell. Every cell has a plasma membrane.without the plasma membrane the content of the cell will not work as the system.Plasma membrane is made up of phosopholipid bilayer
Cell wall is a layer outside the cell membrane and it also provides support to the cell's structure. it gives the plant it's actual shape.it determines what can enter and exist the cell. The cell wall also makes sure that the cell does not burst if there is more water in the plant than its requirement. The cell wall also protects the cell from any pathogens or insects that can harm the plant
Answer: Option C.
Explanation:
Tumor suppressor genes are genes that help to control cell growth or division. It cause the production of protein which is important in cell growth. It encode protein that slow or inhibit progression in a specific stage of cell cycle leading to DNA repair or cell adhession. If the cells grow uncontrollable, it leads to cancer. When there is mutation of tumor suppressor genes,it result in reduction in its function.
