Answer: Scientists use what is called the Fluid Mosaic Model to describe the cell membrane's structure and function.
Explanation:
The cell membrane is selectively permeable, or "semi-permeable", meaning that the membrane only allows certain substances to enter or leave the cell.
Answer:
Cytoplasm: Fluid between the cell membrane and the nucleus. helps protect organelles
Nucleus: A part of the cell containing hereditary information and is responsible for growth and reproduction; the "command center" of the cell.
Ribosome: A small particle in the cell that can make proteins.
Endoplasmic Reticulum: A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
Golgi Apparatus: A cell structure that helps make and package materials to be transported out of the cell or for storage inside the cell.
Lysosome: Cell organelle filled with enzymes needed to break down certain materials in the cell, such as large food particles or old parts of the cell. May be found only in animal cells.
Vacuole: Saclike storage structure in the cell. can store water, nutrients, and even toxic substances.
Mitochondrion: An organelle containing enzymes responsible for producing energy. (Metabolism/respiration)
Chloroplast: An organelle found in the cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis).
Cell membrane: The thin, flexible barrier around a cell; controls what enters and leaves the cell.
Cell wall: The structure outside of the cell membrane that is used to provide support and protection. Present in plants, algae, fungi, and many prokaryotes.

Explanation:
Bronchial/Tracheal cells are from the lining of the bronchi/trachea, the network of tubes used to convey air to the lungs. Bronchial/Tracheal cells are responsible for producing lubricating mucus to keep the airways functional and they are a type of epithelial cell, a term used generally to refer to cells lining the inside or outside of the body. These cells generate mucus and a number of other compounds, which play an important role in respiration.

Answer:
With a warm front, boundary between warm and cold air is more gradual than that of a cold front, which allows warm air to slowly rise and clouds to spread out into gloomy, overcast stratus clouds. Precipitation ahead of a warm front typically forms into a large shield of steady rain or snow.
