FIRST ONE
Explanation:
add energy in the form of heat to get the change in the state of matter.
<span>Enhanced Periglacial
Geomorphic processes resulting from seasonal thawing of snow in permafrost areas where the runoff refreezes in wedges, fissures, cracks and other structures. Periglacial areas can be enviroments where freezing and rethawing significantly restructure or modify the surrounding environment.</span>
Answer AND Explanation:
The variations that Darwin regarded as raw materials for the process of evolution have been traced to changes that occur at the gene level or the chromosome and these changes are called mutations. Organisms with beneficial mutations are able to pass them on to their offspring during reproduction. Transmission of such mutations through many generations could lead to the emergence of new species. The emergence of new species requires a long time and is also affected by the rate of mutations that a particular species undergoes. This leads to evolution.
ATP is like a charged battery, while ADP is like a dead battery. ATP can be hydrolyzed to ADP and Pi by the addition of water, releasing energy. ADP can be "recharged" to form ATP by the addition of energy, combining with Pi in a process that releases a molecule of water.
The right answer is C. I think, a. and d. are obviously not serious. B is not true, because Ag and Au are in the same group in the periodic table and therefore have the same number of electrons in the last level. So, they form ions with the same charge. C is true beacause Ag and Au have different numbers in the periodic table and different amount of protons and neutrons in their nucleuses.
