Sam drives an excavator at an open surface strip coal mine. which type of coal is he most likely to collect closest to the surfa
gizmo_the_mogwai [7]

Sam drives an excavator at an open surface strip coal mine. He has the most tendency to collect the lignite coal which is found in the outermost surface of the earth.

<h3>What is Lignite?</h3>

The brown coal known as lignite, which is found in the topmost layer of the earth's crust, is frequently referred to as such and is essential for commercial use due to the fact that these coals are the only ones used for the majority of applications.

Electricity produced from lignite is plentiful, affordable, dependable, and environmentally friendly. Lignite is a flammable mineral that ranges in color from dark brown to black and was created over millions of years by the partial decomposition of plant matter under conditions of elevated pressure and temperature in an atmosphere devoid of air.

For water to enter the ground there must be?
elena-s [515]

Answer: Percolation

Explanation: It is the ability of water to sip in into the ground. Percolation is the process wherein the ground absorbs water up to the amount it can hold. When the soil or ground is saturated with water it loses its ability to absorb water and causes it to run off. Unsaturated ground can absorb more water through percolation process.

A protein domain is another phrase describing what type of structure of a protein?.
dlinn [17]

Answer: A protein domain is a region of the protein's polypeptide chain that is self-stabilizing and that folds

independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains.

One domain may appear in a variety of different proteins. Molecular evolution uses domains as building blocks and these may be recombined in different arrangements to create proteins with different functions.

In general, domains vary in length from between about 50 amino acids up to 250 amino acids in length.

The shortest domains, such as zinc fingers, are stabilized by metal ions or disulfide bridges. Domains often form functional units, such as the calcium binding EF-hand domain of calmodulin.

Because they are independently stable, domains can be "swapped" by genetic engineering between one protein and another to make chimeric proteins.
