A scientist cites fossil evidence to argue that modern whales evolved from relatively small, land-dwelling mammals. The scientis

t claims that a variety of fossil findings can be ordered in a sequence that demonstrates the evolutionary lineage.
Which analysis of the fossils would be most useful to support the scientist's claim?

A. width and length measurements, which should be the same for homologous bones
B. mineralization analysis, which would identify the specific minerals in each fossils
C. radiometric dating, which would show the absolute age of each fossil
D. biogeography, which should show that all the species lived in the same region.

What causes an ecosystem to move from a primary successional stage towards a relatively-stable mature ecosystem?
Gnoma [55]

Answer:

The correct answer is "secondary succession, an ecological succession step where an area previously occupied by living beings is disrupted".

Explanation:

In ecological succession, an ecosystem changes and develops through a series of steps. The first step, is the primary successional stage where rocks or other sedimentary structures are colonized by microorganisms. The second step, where the ecosystems changes towards a relatively-stable mature stage, occurs when an area previously occupied by living beings is disrupted. This step is named secondary succession, and the most clear example of this phenomena occurs when wildfire clears oak and hickory forests.

This confused me.

The answer is A, denature.

As each type of enzymes has its own optimum temperature, like the temperature that they work fastest at, so if the temperature goes too high above the optimum, the 3D structure of the enzyme breaks apart and deforms and they can no longer bind with substrates thus no longer works. In this scenario, we say the enzyme is denatured.

Note that only if the temperature is too high can make the enzyme denature, if the temperature is too low, instead, the enzyme would be inactive, but once the temperature goes back to normal, they work again. Unlike denatured enzymes, which does not work even if the temperature goes back to normal.
