Answer:

The correct answer is "Charles Darwin and Alfred Russel Wallace".

Explanation:

Charles Darwin and Alfred Russel Wallace are two of the most prominent scientists regarding evolutionary biology. In 1859, the famous book "The origin of the species" by Charles Darwin explained that species develop new traits along several generations, where the traits that are advantageous for the species remain. Alfred Russel Wallace, as well as Charles Darwin, was a naturalist that performed many research expeditions. These two men shared many letters and both concluded that variation of traits might provide better odds of survival in certain environments, where natural selection works as a selector of traits.

Lynna [10]

Answer:

250 N/m2

Explanation:

Shear stress on cells lining the walls of the blood vessels  is equal to 2020 dyne/cm2

In terms of Newton/square meter, shear stress is equal to

20*\frac{dyne}{cm^2}  (\frac{10^{-5}N}{1 dyne} )*(\frac{1 cm^2}{10^{-4}*m^2} )\\= 2.0 N/m2

Shear modulus is equal to shear stress divided by shear strain

Thus, shear modulus is equal to

= \frac{2.0}{0.008} \\= 250N/m2

Answer:old earth:

At its beginning, Earth was unrecognizable from its modern form. At first, it was extremely hot, to the point that the planet likely consisted almost entirely of molten magma. Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed.The early Earth's atmosphere had a very low concentration of oxygen compared to today. 2.4 billion years ago, the oxygen concentration in the atmosphere was less than one part per billion and the iron concentration in the ocean was much higher than today.At its beginning, Earth was unrecognizable from its modern form. new earth:

"Today's Earth (TE)" is JAXA's land surface & river simulation system developed under the joint research with University of Tokyo. The system distributes & visualizes various hydrological products and their magnitudes for disaster monitoring and hydrological research.

The early Earth was very different from our Earth today. The early Earth experienced frequent impacts from asteroids and meteorites and had much more frequent volcanic eruptions. There was no life on Earth for the first billion years because the atmosphere was not suitable for life.
