The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. ... Or, igneous rock can form above ground, where the magma cools quickly.
The Tectonic Cycle is the process in which tectonic plates are created at rift zones where molten material pushes plates apart and destroyed at subduction zones as oceanic plates descend into the mantle. But only oceanic plates are subducted.
The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Ice and snow can sublimate directly into water vapor. ... Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff.
The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbon dioxide from the air and use it to make food. Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration
The nitrogen cycle involves three major steps: nitrogen fixation, nitrification, and denitrification. It is a cycle within the biosphere which involves the atmosphere, hydrosphere, and lithosphere. ... Instead, they depend on a process known as nitrogen fixation.
Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil.
A point mutation can either be silent, missense, or nonsense. In silent mutations, the codon is changed but the encoded amino acid is not changed. This is because different codons code for the same amino acids. Missense mutations will have a significant effect on the protein because the amino acid is replaced by another. A nonsense mutation will result to a fragmented protein because the mutation will lead to the formation of a stop codon which will stop the translation process.
Answer:
It's solid and hard.
Explanation:
The form of apatite use in toothpaste is hydroxyapatite which is a natural occuring minerals that is made up ofcalcium phosphate. The majority of the enamel and dentin in your teeth is made from a form of hydroxyapatite. It form hexagonal crystals. Toothpastes that contain hydroxyapatite can help remineralize the enamel, reducing the risk of cavities and erosion. It's physical properties to know ( solid and hardness) help to strengthen or make the teeth bone strong and also give the bone rigidity.
