The answer is molecular clocks.

Molecular clocks use rates of mutation to measure evolutionary time. This technique is based on the fact that mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages and vice versa.

During which stage of mitosis do the centrioles move to the opposite poles of the cell?

noname [10]

During the cell cycle, the centrioles are made during interphase. The centrioles move to opposite sides of the cell and spindle fibers form a bridge between them during prophase, which is one stage out of the four stages in mitosis.

a small volcano is erupting lava with high amounts of silica what type of volcano is likely to build up from these eruptions

Lelu [443]

Shield volcanoes,This is caused by the highly fluid lava they erupt, which travels farther than lava erupted from stratovolcanoes.

The steady accumulation of broad sheets of lava Low volumes of such lavas layered over long periods of time are what slowly constructs the characteristically low, broad profile of a mature shield volcano

Which statement about the balanced equations for nuclear and chemical changes is correct? (1 point) Both are balanced according

grigory [225]

Both nuclear and chemical equations are balanced according to the total mass before and after the change.

In every equation or reaction, the total mass of the reactants must be equal to the total mass of the products. In other words, all reactions - be they chemical or nuclear - must obey the law of conservation of mass.

The law of conservation of mass states that mass can neither be created nor destroyed, but can be converted from one form to another during a reaction.

Thus, in order to balance reactions involving chemical or nuclear reactants, the total mass before the reaction must be equal to the total mass after the reaction.
