Answer:
Cell division
Explanation:
Everything starts from the union of a sperm and an egg, which gives rise to a cell, which has to become an adult organism. For this, this cell divides in such a way that in each division exactly the same genetic information is maintained. The cell is the reproductive unit of living beings. Throughout its life the cells are nourished and increase in size. When a cell reaches the appropriate size, it usually gives rise to two cells similar to the original cell. Cell Theory is one of the fundamental bases of biology and it is where the base of the constitution of living beings and the fundamental role of cells in them is summarized. It is formulated in the first place thanks to observations and formulations of Theodor Schwann ( physiologist) and Matthias Schleiden (botanist).The current third principle of cell theory, formulates that a cell comes from another cell, by cell division or by formation from stem cells. The oldest and most primitive cells in the world are prokaryotes (without a cell nucleus).
It transfers from being to being, from the sun, where it starts, to every other being after.

Answer:
It is important that he human trachea is reinforced with cartilaginous rings to keep the passage open as pressure keeps fluctuating during the process of breathing.
Explanation:
The trachea is reinforced with cartilaginous rings as it doesn't allow the trachea to collapse in our day to day lifestyle. It also keeps the air way passage open in spite of the continuous pressure changes during breathing.
The rings are not complete posteriorly to provide another advantage, that is it allows the esophagus to expand anteriorly ( inside the body) when we swallow food.
The ribosome binds RNA to synthesize protein.
The nucleus is the core of a cell, giving it its functions.
The endoplasmic reticulum is basically the brain of a cell which distributes throughout the cell.
The golgi apparatus transports lipids and creates lysosomes.
None of these organelles are correct.
However:
The lysosome has digestive enzymes that break down and recycle waste products in the cell.
The cell membrane separates the waste from all cells to the outside, which will eventually be taken away by some other external force, like blood flow or scratching.
Hope that helped.
