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.

Discuss and explain the correlation between thirst and kidney function​
Pachacha [2.7K]

The correlation between thirst and kidney function is the following:

Thirst is the regulator of the state of hydration, necessary to eliminate the osmotic load, it can help preserve kidney function.

The instantaneous perception of osmolarity in the blood allows us to generate the sensation of thirst.

In other words, this sensation is in turn caused by a high concentration of osmolytes (compounds that affect osmosis, or the way it is measured, osmolality or osmolarity) or by hypovolemia.

The receptors that control cellular dehydration are called osmoreceptors and are located in the lateral preoptic area.

Osmoreceptors detect this decrease in cellular water and trigger thirst, as well as the release of Anti-Diuretic Hormone into the bloodstream.

Antidiuretic hormone helps regulate the amount of water in the body by controlling the amount of water excreted by the kidneys.

Therefore, we can conclude that the sensation of thirst appears the sodium concentration is higher than normal, when drinking water, the concentration gradient is reduced, which allows the normal functioning of kidney function.

What type of syndrome is this Karyotype
Ira Lisetskai [31]

Answer:

Patau's syndrome

Explanation:

Patau's syndrome is a genetic disorder caused by one additional chromosome 13, and therefore it is an aneuploidy caused by an extra chromosome (i.e., a trisomy). Individuals with Patau's syndrome have 47 chromosomes instead of 46 in some or all their somatic cells. This syndrome seriously affects fetal development, usually resulting in miscarriage, stillbirth or in neonatal death. The incidence of this syndrome is around 1/5,000 births.

Which type of cell is most likely to have the most mitochondria? muscle cells in the legs of a marathon runner nondividing cells
MatroZZZ [7]

Answer:

muscle cells in the legs of a marathon runner

Explanation:

Mitochondria are the powerhouse of cells and serve as a site for the aerobic stage of cellular respiration. Cellular respiration is complete oxidation of nutrients in the presence of oxygen to produce a large number of ATP molecules. Therefore, the cells that require more ATP molecules as an energy source would most likely have a greater number of mitochondria.

Muscle cells are responsible for body movement. Muscle cells in the legs of a runner would require a constant supply of ATP during running since muscle contraction requires ATP. To sustain the continuous muscle contraction during the marathon, the muscle cells in the legs of the runner would have most number of mitochondria.
