B snow melting because it turn to solid t liquid which is more energy<span />
B. An atom whose nucleus is unstable and emits particles and and energy. This is a Radioactive isotope.
The atomic nuclei of constituent atoms of the same element include the same number of protons but different numbers of neutrons. Radio isotopes are an element's radioactive isotopes. They can alternatively be described as atoms with an excess of energy in their nucleus or atoms with an unstable ratio of neutrons to protons. A radioisotope's unstable nucleus can form either spontaneously or as a result of a deliberate alteration of the atom. Radioisotope production can occur using either a cyclotron or a nuclear reactor. Molybdenum-99, which has a high neutron content, can be produced most effectively in nuclear reactors, whereas fluorine-18, which has a high proton content, can be produced most effectively in cyclotrons. Uranium is the most well-known illustration of a radioisotope that is found naturally. Uranium-238 constitutes all naturally occurring uranium with the exception of 0.7%.

Answer:
The correct answer is statement A.
Explanation:
The procedure of purifying ocean water, that is, the saline water so that it can become suitable for drinking is termed as desalination. Almost 70 percent of the Earth is covered with water and of this only 3 percent is used for drinking purposes. On a huge scale, the process of desalination would require the boiling of water, which would eventually require an enormous amount of energy.
Reverse osmosis and electro-dialysis are the methods used for desalination. However, these procedures are very costly and cannot be performed on a huge level as it can affect the economy of various countries.
A mother passes on her mt(DNA) or mitochondrial DNA which sometimes includes genetic material but a father only passes down a Y chromosome if he has a son. No genetic material.

<h3>Interphase</h3>
<h2>
Explanation:</h2>
<h3>The cell cycle is the period of time from the beginning of one cell division to the beginning of the next. The longest stage of the cell cycle is called interphase. Interphase is the stage that occurs in between cell divisions. During interphase, the cell grows and develops and performs its functions.</h3>
