Lina20 [59]

<span>Answer:  a)  a series of anatomical traits that distinguish Cro-magnon features from Neandertals.</span>

<span>Neanderthals (Homo neanderthalensis) were first discovered in Germany in 1856 and are believed to emerged between 100,000 and 200,000 years ago. </span>

<span>Significant differences found in the human and </span>Neanderthal includes<span>: 1) their DNA, 2) the brain of a Neanderthal had a raised larynx and was also bigger, and  3) Compared to modern humans, Neanderthals had bigger and muscular body but with shorter legs.</span>

Cro-magnon is<span> the earliest known Western European example of our species who lived  35,000 and 10,000 years ago. They are believed to be actually modern in every anatomical respect. They are much like us.</span>

<span>Neanderthal and Cro-magnon were believed to overlap in Europe for a thousand years but long-term interbreeding was not seen. </span>

The characteristics of the active site microenvironment of an enzyme can be largely independent of individual catalytic mechanis
Valentin [98]

Answer: (1) Providing an optimized orientation of the substrate.

(2) Decreasing the ∆G in reaction.

(3) Excluding excess water.

Explanation: The active sites of enzymes increase the rate of reaction because they decrease the activation energy of the reaction,and the physical microenvironment provides an optimal orientation of the substrate relative to reactive functional groups while excluding excess solvent,such as water.

Although some active sites may have amino acids that form salt bridges with the amino acids from a substrate,not all do, so this is not a generic strategy of active site microenvironments
