History of the Atom Reading Comprehension is stated below.
The Greek word atoms, which implies unable to cut or divide, is where the name "atom" originates. The atom was believed to be invisible at that time. In contrast to Democritus, Aristotle presented his own theory regarding the nature of matter. Democritus' thesis provided a clearer explanation of the situation, but Aristotle's ideas won out because of his greater stature.
According to his ethics, the only way to acquire eudaimonia—a state of bliss or contentment that is the highest form of human life—is by becoming wonderful. Dalton eventually looked more closely at gases as a result of his fascination with atmospheric pressures. John Dalton is well recognized for his contributions to human optics and for introducing the atomic theory to chemistry.
After discovering the electron, Thomson went on to suggest a model for the atom's structure. In Thomson's "plum pudding" atom model, a positively charged "soup" was surrounded by negatively charged electrons. Thomson made this discovery after his research assistant Francis Aston used a mass spectrometer to fire ionized neon through a magnetic and electric field and noticed two unique deflections. Thomson came to the conclusion that neon existed in two isotopes with distinct masses.

Answer:
Biological evolution refers to the cumulative changes that occur in a population over time. These changes are produced at the genetic level as organisms' genes mutate and/or recombine in different ways during reproduction and are passed on to future generations.
Explanation:
A/Cell membranes and cell walls are selectively permeable and aid in communication.
Explanation:
Cell Membranes or cell wall have phospholipid bi layer which functions
as a selectively permeable barrier that separates an internal
environment from an external one. They are selective permeable through
passive process (concentration gradient) allowing certain molecule
diffuse into cells
Answer:
C. Absorbency, because all soil does not absorb water, such as sand. The other components such as clay, silt, and organic matter are much smaller and absorb much more.
