Both coal and diamonds are forms of elemental carbon. Coal is brittle while diamonds are considered to be the hardest Of all sub
Art [367]

arbon, as with many elements, can arrange its atoms into several different geometries, or "allotropes." In pure diamond, every carbon atom is covalently bonded to exactly 4 other carbon atoms in a very specific and energetically favorable geometry. The diamond cannot be broken or scratched unless many covalent bonds are broken, which is difficult to do. In another common allotrope, graphite, every carbon atom is covalently bonded to only 3 other carbon atoms, and the atoms are arranged in sheets that are not covalently bonded to each other. The sheets can be broken apart easily, ultimately meaning that graphite can be easily scratched. Coal is composed of particles of different allotropes of carbon, and some "amorphous carbon," which has no defined geometry in its atomic structure. Without a continuous network of covalent bonds, coal is easily scratched (i.e. it is not hard).

The lengthy small intestine receives secretions from the ____________ and ____________, completes digestion of the nutrients in
vitfil [10]

Answer:The lengthy small intestine receives secretions from the ______pancrease______ and ______liver______, completes digestion of the nutrients in _________chyme_______, absorbs the products of digestion, and transports the remaining residues to the ________large________ intestine.

Explanation: digestion of food is necessary for absorption of nutrients. In this process food is broken down into forms that can be absorbed by the body . food is broken down by the teeth and the enzymes in saliva,when it is in the mouth. From there it moves to the stomach through the oesophagus. In the stomach, the content is further mixed with enzymes and the churning breaks down food further.From the stomach food moves to the small intestine. In the small intestine, digestive enzymes from the pancreas and liver acts on food. The small intestine is where digested food is absorbed.it has a large surface area and finger-like projection called villi to carry out the function of absorbing nutrients.

From there, undigested food us passed to the large intestine from where it is passed out through the anus

List the sequence of events involved in the alternation of generations in land plants
Keith_Richards [23]
<span>The sequence of alternation of generation is; gametes->zygote->sporophyte->spores->gametophyte->gametes. The attached diagram shows clearly this looped cycle. Alternation of generation occurs in a more advanced land plant that has distinct haploid and diploid phases in their life cycle. The diploid phase usually involves the sporophyte while the haploid phase involves the gametophyte</span>

Earth has a great variety of surface features that are caused by weathering and erosion. Which of the following describes a chan
Sidana [21]

Answer:

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

 

Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.

 

Weathering and erosion constantly change the rocky landscape of Earth.
