The correct answer is C. When two species separated from a shared ancestor

Explanation:

In biology, the term "molecular clock" refers to a technique biologist use to study the origin of mutations that made one; species led to others. This implies through the molecular clock scientist can determine the evolution and species and the time in which two species separated from a shared ancestor or diverged. This technique relies mainly on biomolecular information based on sequences of DNA as differences in DNA between two species with a common ancestor marks the divergence of these species, also molecular clocks use the comparison of fossils to confirm evolutive divergence. Therefore, it can be concluded biologist use molecular clocks to try to measure "when two species separated from a shared ancestor".

Nikitich [7]

Answer:

a. destroyed

b. osteoclasts

c. proteolytic enzymes

d. hydrochloric acid

e. blood

f. low

Explanation:

Resorption is the loss of substance from any mineralized tissue, mediated by cellular and humoral systems of their own. The four mineralized tissues of our economy, bone, cement, dentin (mineralized fraction of the dentino-pulp functional complex) and enamel, offer different degrees of resistance to resorption. The bone has the greatest lability and the enamel the least. The fact that the bone tissue is the least resistant to resorption is used to move and reposition teeth by controlled forces (orthodontics); and the fact that the enamel is the most resistant has led to think that it does not suffer from resorption.

Osteoclasts They are the spring cells par excellence; they belong to the lineage of the monocitomacrophages. They are large, multinucleated mobile cells, with a clear area and a rough brush border that live for about two weeks and disappear by apoptosis (cell death programmed by fragmentation in membrane particles that allows their phagocytosis without inflammation). They are responsible for the destruction of the organic and inorganic parts of the mineralized bone fraction. They are active both in the processes of the physiological renewal of the bone and in those of its pathological loss.

Naily [24]
The observation that indicates that it is a living thing that is multicellular because it has membrane-bound organelles. The correct answer is option B. Multicellular organisms' cells are macroscopic which are naked to the visible eye. These organisms are eukaryotic so this means that their cells contain membrane-bound structures.
