The main purpose of alcohol fermentation is to produce ATP, the energy currency for cells, under anaerobic conditions
Explanation:
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.
Answer:
1: 7.8 cm
2: .7 cm
3: 5.55 cm
For the other questions, you have to use a ruler yourself and measure using cm. :)
1 cm = 10 millimeter. To convert, just add a 0 to the end of cm to find the mm (or move the decimal one place to the right.)
For example, 2.6 cm = 26 mm / 5 cm = 50 mm. Hope this helps!
