Dmitri Mendeleev first organized the periodic table by atomic mass. Later, Henry Moseley improved the design of the periodic table by organizing the columns into families.

<h3>How was the periodic table created?</h3>

Dmitri Mendeleev (1834-1907), in 1869, while in Russia, had the same idea as Meyer, who was studying in Germany. He more meticulously arranged a periodic table where the 63 known chemical elements were arranged in columns based on their atomic masses.

With this information, we can conclude that Dmitri Mendeleev first organized the periodic table by atomic mass. Later, Henry Moseley improved the design of the periodic table by organizing the columns into families.

Which of the following is not a physiological mechanism regulated by timing?

Lady_Fox [76]

Answer:

Viral reproduction in a host cell.

Slow down its metabolic rate and lower its body temperature

Explanation:

Viral reproduction in a host cell is not associated with the physiological mechanism regulated by timing. The viral reproduction occurs in the host cell whenever the virus enters the host cell. The virus attaches itself to a host cell and injects its genetic material into it. For reproduction, virus use resources of the host cell to make more viruses and spreads in the neighboring cells. This reproduction does not depend on the specific time, it occurs when it penetrates in the host cell. Skunk slow down its metabolic rate and lower its body temperature when there is extreme cold and food shortages during the long winter months
