A channel protein serves as a tunnel across the membrane into the cell. More specifically, channel proteins help molecules across the membrane via passive transport, a process called facilitated diffusion. These channel proteins are responsible for bringing in ions and other small molecules into the cell
D, because cells create roots. B would work, but it is not directly responsible.
Answer:
Option D, erosion, deposition, compaction, cementation
Explanation:
Sedimentary rocks are formed from the eroded soil. Therefore, erosion is the first step in formation of sedimentary rocks.
The eroded soil or rock is carried by carrier agents such as wind, water etc. and deposited at some place where it gets compacted under its own weight. After deposition and compaction, physio-chemical processes take place to produce chemical bonding between the deposited granular particles. Chemical interactions causes cementation of the compacted material
Hence, option D is correct
Called bioconversion although it can also be referred to as bio transformation
