812.5/1.25=650
So it will take 650 years to widen another 812.5 centimeters

Answer:

This is a simple math problem, and for that, the rule of three can be used.

Explanation:

The rule of three in this case will work like this, we have three informations on the question, and we're searching for the fourth one, so by that let's do the rule of three below:

1,25cm - 1 year

812,5cm - X

After that we multiply 1,25 with X and 1 with 812,5, the result is this:

1,25X = 812,5

X = 812,5/1,25

X = 650

So the answer to the question is 650 years to widen another 812,5 centimeters.

Answer:

In addition to biology, evidence drawn from many different disciplines, including chemistry, geology, and mathematics, supports models of the origin of life on Earth. In order to determine when the first forms of life likely formed, the rate of radioactive decay can be used to determine the age of the oldest rocks (see optional problems C and D, below) exposed on Earth’s surface. These are found to be approximately 3.5 billion years old. The age of rocks can be correlated to fossils of the earliest forms of life. A. The graph compares times of divergence from the last common ancestor based on the fossil record with a "molecular time" constructed by comparing sequences of conserved proteins to determine a mutation rate (after Hedges and Kumar, Trends in Genetics, 2003). Explain how such a molecular clock could be refined to infer time or the evolution of prokaryotes. B. Using a molecular clock constructed from 32 conserved proteins, Hedges and colleagues (Battistuzzi et al., BMC Evol. Biol. 2004) estimated the times during which key biological processes evolved. A diagram based on their work is shown. Connect the time of the origin of life inferred from this diagram with the age of the oldest fossil stromatolites and the age of the oldest exposed rock to show how evidence from different scientific disciplines provides support for the concept of evolution. Evaluate the legitimacy of claims drawn from these different disciplines (biology, geology, and mathematics) regarding the origin of life on Earth. The oldest known rocks are exposed at three locations: Greenland, Australia, and Swaziland. The following application of mathematical methods provides essential evidence of the minimum age of Earth.

Kitty [74]

The appropriate response is Facilitated Diffusion. It is the procedure of unconstrained detached transport of atoms or particles over a natural film by means of particular transmembrane indispensable proteins.
In the cell, cases of atoms that must utilize facilitated diffusion to move all through the cell film are glucose, sodium particles, and potassium particles. They pass utilizing transporter proteins through the cell film without vitality along the fixation slope.
