The desert biome is the driest where common floras are cacti, and faunas are snakes and lizards. This is commonly seen as a barren area of land where rain rarely occurs. The living conditions within this biome is very hostile for both plant and animal life. Animals survive by hiding under rocks and soil to protect themselves from the excessive heat of the sun.
The digestive system is the system of organs that help you digest foods and extract nutrients that your body uses
Poop. I don't really know what you are asking but the excretory system removes the stuff from our stomach that we cant use or stuff that already has all of the nutrients that we need removed. Hope this helps
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.
In humans gene flow usually comes about through the actual migration of human populations, either voluntary or forced. Although gene flow does not change allele frequencies for a species as a whole, it can alter allele frequencies in local populations.
Hopefully this helps.
