Answer: Coal seams refers to those distinctive thin beds of coal that are found to be existed in between two sedimentary rock layers. It is easily distinguishable because of its characteristic color such as dark brownish or blackish in color.

Coal is obtained from the dead remains of plants and trees that were buried millions of years ago, due to action of extreme pressure and temperature conditions. The process by which these vegetative matters are converted into coal is known as the carbonization.

This coal has extensive use such as the generation of electricity as well as in the production of steel and are obtained by two methods, such as the open cast mining and underground mining.

Coal seams are far deep underground to be considered for opencast minings. These coal seams require underground mining. Since it is too deep underground, it can be used for mapping and correlation of sedimentary rocks or as a key bed.

Which tissue predominantly contains fibers that form a netlike support structure?

inessss [21]

The tissue that predominantly contains fibers that form a netlike support structure is the connective tissue.

<h3>What is the connective tissue?</h3>

Connective tissue is one of the types of primary tissues which has the function of supporting and integrating the rest of the cells since it is the tissue that gives a union of different tissue elements that make up the organs.

This tissue helps move nutrients to the cells they contain in order to give them nutrition, they can also transport other types of substances. Within the types of connective tissue are cartilage, adipose tissue and blood.

Therefore, we can confirm that the tissue that predominantly contains fibers that form a netlike support structure is the connective tissue.

Deficiencies of carnitine, carnitine acyltransferases, or carnitine/acylcarnitine translocase affect the metabolism of long‑chai

vovikov84 [41]

Answer:

CPT-1 deficiency can cause:

Symptoms of low blood sugar (hypoglycemia)

Liver problems, such as an enlarged organ

Damage to the nervous system, caused by liver (liver) problems

Coma and sudden death

Heart failure

CPT-2 deficiency can affect each person differently, depending on how well the CPT-2 protein is working. Symptoms can be mild to severe. For certain periods, people with this deficiency may not have any symptoms. Very serious forms can affect newborns or babies. These are rarer.

The myopathic form of CPT2 deficiency causes milder symptoms. It does not cause heart or liver problems. People with this form generally have a normal life expectancy. Symptoms can start at any time up to age 60. They can appear if you skip meals, exercise a lot, or get sick. Symptoms may include:

Symptoms of low blood sugar (hypoglycemia)

Temporary muscle pain

Muscle damage

Muscular weakness

Dark urine

So, it can be said that the myopathic form is the least severe and is characterized by recurrent episodes of rhabdomyolysis, muscle pain and weakness triggered by prolonged physical exercise, fasting, viral illness or extreme temperatures. The severe infantile form is characterized by severe intolerance to fasting, leading to metabolic disorders such as hypoketotic hypoglycemia and hepatic encephalopathy. The neonatal lethal form presents with symptoms of the infantile form as well as dysmorphic manifestations (eg, cystic renal dysplasia).

Explanation:

Carnitine palmitoyltransferase (CPT) deficiency is a rare condition that causes muscle weakness and other symptoms. It occurs due to a problem with one or two enzymes, CPT1 or CPT2.
