The populations living on a rough, steep mountain would have a higher rate of speciation than this living in a large, open grass
exis [7]

The correct answer is option C, that is, have a wider range of environments.  

It has been known that geographic isolation is a general way for the initiation of the process of speciation, like the rise of mountains, rivers changing course, migration of organisms, continental drift, due to this what was once a steady population gets differentiated into two or more kinds of smaller populations.  

A mountain range, due to distinctions in temperature and precipitation as a result of different altitudes, can lead to a higher rate of speciation. Due to these differences, a single mountain range can exhibit an enormous array of biodiversity and climate zones.

When muscle tissue is exercising under anaerobic conditions, the production of ______ is important because it ensures a continuo
MatroZZZ [7]

Given what we know about the biological mechanisms behind anaerobic exercise, we can confirm that the production of lactate ensures a continuous supply of NAD.

In order for us to undergo any physical exercise, it is imperative that we are able to produce energy within our cells. The energy used by cells is in the form of a molecule by the name of ATP, which is produced primarily through a process known as <em>Glycolysis</em>.

This is relevant given that in order for glycolysis to happen, a key protein is required known as NAD+. Lactate is produced from pyruvate only under anaerobic conditions because these are conditions that lack oxygen which is the only other source of NAD+, therefore, pyruvate must be converted to lactic acid to make it possible to continue glycolysis and the production of ATP.
