Since igneous rocks form at high temperatures, and under pressure conditions ranging from one to several atmospheres. However, the conditions at the Earth's surface are somewhat different than the conditions at which most rocks and minerals form. Therefore, the materials are no longer at equilibrium when they are exposed to surface conditions. Under these conditions, there is a tendency for all ordered systems to seek lower levels of energy or order. This is all done through weathering.

Answer:
A biochip or DNA chip or DNA microarray is a slide that contains the different fragments of DNA . The DNA microarray technique is used to study the expression level of various genes simultaneously. For this the researcher:
A. Attach the fragments of DNA about 500 to 5,000 bp that are produced by the controlled growth of the nucleotides by providing the narrow beam of light and synthesised by the PCR technique on to the slide in the form of dots or spots.
B. In dots, the reporter oligos or probes are attached which are used to hybridize the cDNA to the microarray. The cDNA is labeled with the fluorescent molecules called fluorophore.
C. After hybridization, the probe-target hybridization is detected by placing the washed array in the confocal fluorescence microscope which observes the pixel and helps calculate the fluorescence intensity.
Answer:
What little is known is that the Earth's magnetic field creates the so-called A "magnetic shield" that protects against other dangerous forms of radiation, namely cosmic rays and solar wind.
While there is no danger of losing the Earth's gravitational field, the Earth's magnetic field is declining faster than any other geophysical phenomenon. This continuous loss of the Earth's magnetic field, and the associated increase in harmful radiation, are beyond human control.
In addition to the growing problems of Earth's environment, there are other conclusions that can be drawn from the weakening of its magnetic field:
1) C-14 carbon dating should be reconsidered;
2) There is an age restriction for both the Earth's magnetic field and the Earth itself.
Explanation:
Electromagnetism is a branch of classical physics that investigates the causes and interconnections of electrical and magnetic phenomena, explains the light phenomena and laws of optics, and all other types of electromagnetic waves.
The development of electromagnetism began in the early 19th century with the experiments of HC Ørsted and M. Faraday. reached in A. Einstein's special theory of relativity.
On a global scale, two important force fields connect to planet Earth: Earth's gravitational field and Earth's magnetic field. The gravitational field draws us towards the earth, keeping us from flying into space at Earth's rotation. It also prevents the atmosphere from leaving our planet. The atmosphere, on the other hand, provides protection against some types of cosmic healing. For example, ozone in the atmosphere protects from ultraviolet rays, a deadly form of radiation.
Aquaporins would be expected to increase in numbers when there is an insufficient amount of water present in the blood.
Aquaporins are a type of proteins which are present in the integral membrane of the cells. They act as channels and help in the transport of water and small solutes across the membrane.
Whenever there is insufficient amount of water present in the blood, the antidiuretic hormone or the ADH responds. The aquaporins increase in number in the blood. They allow the transcellular reabsorption of water. Due to this fact, more water is able to escape from the collecting tubules and enter the blood.
