In cell biology, the cytoplasm is the material or protoplasm within a living cell, excluding the cell nucleus. It comprises cytosol (the gel-like substance enclosed within the cell membrane) and the organelles – the cell's internal sub-structures. All of the contents of the cells of prokaryote organisms (such as bacteria, which lack a cell nucleus) are contained within the cytoplasm. Within the cells of eukaryote organisms the contents of the cell nucleus are separated from the cytoplasm, and are then called thenucleoplasm. The cytoplasm is about 80% water and usually colorless.[1]
It is within the cytoplasm that most cellular activities occur, such as many metabolic pathways including glycolysis, and processes such as cell division. The concentrated inner area is called the endoplasm and the outer layer is called the cell cortex or theectoplasm.
Movement of calcium ions in and out of the cytoplasm is a signaling activity for metabolic processes.[2]
In plants, movement of the cytoplasm around vacuoles is known as cytoplasmic streaming.
Answer:

Answers:
1) Photons are absorbed by hot gas atoms.
2) Energy is transferred through large-scale movement of material.
3) Energy is released into the photosphere.
The Sun interior is divided into three regions: the inner core, the radiative zone and the convection zone.
The inner core is the central region of the Sun and all solar energy is produced in the core by nuclear fusion.
Radiative zone is around the inner core and in this area energy is transported by radiation.
The convection zone is the outer-most layer of the interior and in this area energy is transported by convection.
Explanation:
In order to find the molecular formula, we have to find the empirical formula first of all.
It is known that is a styrofoam, elements present are carbon and hydrogen atoms.
Element % Atomic mass Molar ratio Simple ratio
C 92.25 12.01 
= 7.68 
= 1
H 7.75 1.008 
= 7.68 = 1
As empirical formula of styrofoam is C_{x}H_{x}.
Hence, empirical mass = (12.01 + 1.008) g/mol = 13.018 g/mol = 13.0 g/mol (approx)
Molar mass given is 104 g/mol.
So, 
= 
= 8
Thus, we can conclude that molecular formula of the given styrene is 
.
