Answer:
True
Explanation:
During the evolution of eukaryotic cells, the complexity of size and their functions increased, so that a proportional increase in the surface of the <u>cell membrane</u> would be necessary, making it possible for the cell to perform several functions at the same time.
Through differentiations of the structures, it was possible to develop intracellular membranes in the form of organelles capable of performing various functions at the same time, such as cellular respiration and digestion.

Answer:
Due to mixing of particles present in the upper layer of limestone with sandstone during deposition.
Explanation:
The parent layer was limestone layer which is older than sandstone layer. This sandstone layer spreads on the limestone layer because of wind. The wind moves these sandstone from other region and their deposition occurs on the limestone layer. During deposition of sandstone, some particles of limestone which are present at the surface mixes with the sandstone so that's why in sandstone layer, small and weathered pieces of limestone are present.
