All cells are surrounded by a cell membrane (option B).
A cell membrane is the semipermeable membrane that surrounds the cytoplasm of a cell.
Living organisms are made up of cells- a lot of them. These cells are the simplest unit and they contain smaller substances that perform different functions called organelles.
However, the cell and its internal organelles are surrounded by a structure called the cellmembrane.
The cell membrane functions to protect the cell from external hazards but also serves as a gateway for substances to enter the cell, hence, it is called semi-permeable.
Hence, the correct option is B.
The complete options are as follows;
A. Vacuole
B. Cell membrane
C. Cell wall
D. Nucleus

Answer:
the end results of mitosis and meiosis are completely different: Mitosis: One diploid cell → two diploid cells. Goal is cell division. Meiosis: One diploid cell → four haploid cells.

Answer:
Nuclear physics is related to chemistry in some way but it is rightly placed under the branch of physics.
Nuclear physics is the field of physics in which atomic nuclei are studied. As in chemistry reactions are studied, nuclear physics also studies the reactions of the atomic nuclei. Hence, in this way, these two fields might co-relate but there are more differences than similarities in the field of chemistry and nuclear physics.
