Answer:
Neutral; protons (H+)
Explanation:
At neutral pH, the hydroxide and proton ions are equal.
Answer:
An acid is a chemical that dissociates releasing free hydrogen ions.
Explanation:
The chemical equation for an acid is HA⇄A- + H+
The free hydrogen ion (H+) is what gives the substance the quality of acid.
Answer:
By analyzing the pelvis bone (sex determination) and the length of the diaphyseal bone and nonsynovial joints (age determination of non-adult skeletons and adult skeletons, respectively)
Explanation:
Bioarchaeologists are professionals that study human skeletons from archaeological sites. Bioarchaeologists can estimate the age and sex of human skeletons and thus determine the health and dynamics of past human populations. In regard to sex determination, the pelvis is a bone that can be used to estimate the sex of an individual with an accuracy higher than 95%. In regard to the age, characteristics associated with bone growth such as, for example, the length of the diaphyseal bone, can be good indicators to estimate the age of non-adult skeletons, while nonsynovial joints (i.e. joints without a synovial membrane) which are commonly called synarthroses or solid joints, can be used to estimate the age of adult skeletons.
