Answer:
Low - The generation of nitrates (NO 3-) requires oxygen, so the oxygen levels will be low
Explanation:
Nitrates are formed when the ammonia react with oxygen present in water. The oxygen which react with ammonia is not the oxygen of water molecule, it is the dissolved oxygen. This oxygen is used by aquatic animals for breathing. If nitrates are formed so the concentration of dissolved oxygen will be lowered which causes suffocation and bad impact on marine organisms and the whole ecosystem will be disturbed.
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.

Bones: they lose calcium, becoming crispy
Muscle: they lose mass
Cartilage: becomes stiffer, but it does not make airway more rigid
D) connective tissue: It includes bone, blood, and lymph tissue, giving support to the skin and internal organs, becoming increasingly stiff when aging.
It should be connective tissue.
