The correct answer is option B, that is, all living organisms are composed of one or more cells, which came from pre-existing cells.
A scientific theory refers to a well-substantiated illustration of some characteristic of the natural world, on the basis of a number of facts, which have been repeatedly confirmed via the experiment and observation. Such fact-supported theories are not hypotheses, however, are reliable explanations of the real world.
During the late 1830s, the zoologist Schwann and the botanist Schleiden were examining tissues and postulated the unified cell theory. According to the unified cell theory, all the living things comprises of one or more cells, the cell is the fundamental unit of life, and the new cells originate from the pre-existing cells.
It's called puberty. The moment in time where a children most likely go from kinda ugly to less ugly. LOL. You are all amazing. !!!!!!
The correct option is : "Golgi apparatus"
What is endoplasmic reticulum?
Endoplasmic reticulum (ER), a continuous membrane structure in biology, is vital for the synthesis, folding, modification, and transport of proteins. It forms a series of flattened sacs within the cytoplasm of eukaryotic cells. An endoplasmic reticulum can be found in all eukaryotic cells (ER). The ER typically makes up more than 50% of the cell's membranous composition in animal cells. The two forms of ER, known as rough ER and smooth ER, can be distinguished by differences in certain morphological and functional properties.

Due to the ribosomes connected to its exterior (cytoplasmic) surface, rough ER is so named because of its rough look.

Only eukaryotic cells have membrane bound organelles. Prokaryotes organelles just float in the cytoplasm.
The explanation regarding the advantage of reproduction that represents the graph should be described below.
Advantages of reproduction:
Here the graph represents the bacteria population that should be raised as the time passes. At the time of 1st hour, the bacteria population should be 50 per ml.
In the second hour, the population should be doubled. In the third hour it should be 200 per ml and in 3 and half hours, the population should be 300 per ml. So here we can see that the population should be doubled with every hour.
