Which statement is an example of a scientific theory?
sergiy2304 [10]

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.

She notices that the muscle cells are loaded with mitochondria while the macrophages have abundant lysosomes. why is this so?
Kaylis [27]

The muscle cells are loaded with mitochondria to allow large amounts of ATP production while the macrophages have abundant lysosomes to digest the debris and dead organisms like bacteria.

Mitochondria are known as the powerhouse of a cell. This is because most of the ATP production used by various systems in their operation is produced by mitochondria. A chemical called NADH is produced in the mitochondrial matrix through the Krebs cycle. The enzymes embedded in the mitochondrial membrane use this chemical to produce Adenosine Triphosphate, generally known as ATP.

Macrophages are phagocytic white blood cells involved in engulfing and killing pathogens. They are involved in the innate immune response of the body. Lysosomes have specialized enzymes that can kill these pathogens.

Muscle cells need to contract or expand for which they require energy. Thus, they have abundant mitochondria. Whereas, the macrophages have abundant lysosomes to help them kill disease-causing pathogens like a virus or bacteria.

To know more about ATP production in mitochondria, refer to the following link:
