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:
The fundamental principle involves the formation of equilibrium and separation into distillate and bottoms governed by the equilibrium composition curve , number of stages and the purity with which the distillate is required.
Explanation:
Distillation is a type of the separation process by physical means of a mixture on basis of its difference in boiling point or vapor pressure .
Where we can just heat the mixture and separate out the components i.e the component with lower boiling point will form vapor easily and can be later condensed whereas the component with higher boiling point will remain as residue.
In case of a distillation column the same principle is applied at different stages to separate multiple components .The stages are known as trays or plates . In general , there is a certain liquid on each of the plate, and the arrangements are made for the ascending vapors to pass through the liquid and make contact with it . The fundamental principle involves the formation of equilibrium and separation into distillate and bottoms governed by the equilibrium composition curve , number of stages and the purity with which the distillate is required.
Answer:
c. Boundary where air masses meet and cold air rises above warm air.
Explanation:
If you wanted to find a sample of fermium,which has an atomic mass of 100 I would look deep under the earth
Metal solids contain a positively-charged cation surrounded by a "sea" of delocalised, negatively-charged electrons.
The electrons are able to move freely, and hence transfer kinetic energy throughout the implement at a much quicker rate than non-metals.
Plastic is made of non-metals (Mostly carbon and hydrogen) and therefore is a poor thermal conductor.
Therefore, by coating the metal utensil in plastic, the rate of heat energy transfer to the person in contact's hand is decreased.
