Answer:
Explanation:crystal size in igneous rocks is determined by how quickly magma or lava cooled to form it.
Answer:
Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive. ... Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.
These three (3) chemical reactions include Hydrolysis, Carbonation, and Oxidation.
• Hydrolysis is a chemical reaction caused by the water in which water responds with the rock and changes the size and chemical arrangement of the minerals that reduces opposition to weathering.
• Carbonation is an involvement of water with carbon dioxide to create carbonic acid. It appears when the rock minerals respond with fragile carbonic acid made when water associates with carbon dioxide in the air that deeds on the rock by breaching and disbanding the mineral substances.
• Oxidation is recognized as rusting, a procedure whereby the rock minerals misplace one or more ions or atoms in the occurrence of oxygen. Once minerals in the rock rust it will develop less opposition to weathering. The oxygen associates with other constituents via oxidation method given that rise to ion or atom lose.
A bacterial infection of the periodontium that causes rapid attatchment loss and poor response to periodontal therapy has a grade of Aggressive periodontal disease
<h3>Periodontium </h3>
The cementum, gingiva, periodontal ligament (PDL), and alveolar bone make up the complex structure known as the periodontium. The periodontium's main purposes are to protect the underlying structures of the tooth from the oral microflora and to enable the tooth to connect to the bone.
An orthokeratinized or parakeratinized stratified squamous epithelium makes up the gingival epithelium. The gingiva, which has connective tissue and epithelial components, covers the supracrestal root surface and the alveolar bone. As it lines the gingival sulcus close to the tooth surface (enamel or cementum) and subsequently joins to it with hemidesmosomes, the gingival (oral) epithelium develops into the sulcular epithelium and junctional epithelium.
