Hi
Well, firstly, <span>Root hairs allow the plant's roots to cover more ground,in this way, giving it the opportunity to extract more nutrients and water from the soil. That's how it works</span>

Explanation:
Cell membranes are barriers which protect and regulate the movement of substances in and out of the cells. It is a semi-permeable and selective structure.
In the passive transport system, substances move along a concentration gradient and it doesn't require energy. The examples of passive transports include; simple diffusion which transports carbon dioxide and oxygen, osmosis and facilitated diffusion which transports charged molecules like ions, sucrose etc.
In active transport, substances move against the concentration gradient. This requires energy. The two main types are: primary active transport, which uses direct metabolic energy e.g Na+/K+ pump, and the secondary active transport system which couples the transported molecules with another molecule moving along the gradient, example the Na+/glucose transporter.

The correct answer is by composition and texture. Composition is that minerals that the rock are made of. Texture refers to the grain size of the different components of that rock. Texture has to do with sizes of mineral grains and other constituents in a rock and how the sizes and shapes relate to each other.
Just follow the rock cycle.
<span>(1) Rock is broken down </span>
<span>(2) Regolith is eroded/transported </span>
<span>(3) Regolith is dumped </span>
<span>(4) Layers begin to compact </span>
<span>(5) Sedimentary rock is buried and turned into metamorphic rock </span>
<span>(6) Metamorphic rock melts to magma </span>
<span>(7) Magma resurfaces as igneous rock</span>
