Elephants have multiple copies of the p53 genes that play an important role in the control of cell division.
<h3>What is the role of p53 genes in elephants?</h3>
P53 is an important regulator of the DNA repair processes and controls uncontrolled cell proliferation. When DNA is harmed, the protein becomes active and aids in orchestrating a response that stops DNA replication and fixes any incorrect copies of the cell. The oncogene MDM2 E3 ubiquitin ligase, another protein, is responsible for deactivating the p53 repair activity in duplicated cells with intact DNA since it is not required.
A human with only two alleles from a single gene has much fewer molecular anti-cancer interactions than an elephant, which has 40 alleles, or versions, from its twenty p53 genes. Although the elephant may appear to have excessive genetic diversity, each of its 40 alleles is structurally slightly different.
I understand the question you are looking for is this:
Compared to humans, elephants have a dramatically low instance of cancer. Elephants have multiple copies of the _____ genes that play an important role in the control of cell division.

Of the total Earth's surface, approximately 20 percent is covered with deserts. The majority of the desert takes place in the area band situated along the 30 degrees latitude in North and 30 degrees latitude in the south. Even some of the deserts are also situated in the regions of mountains.
There are four prime kinds of desert found in the planet. These are:
1. Subtropical deserts: They are the hottest deserts. They are found in Africa, Asia, North America, and South America.
2. Coastal deserts: They occur in cool to warm regions along the coast like the Atacama Desert in Chile and Namib Desert in Africa.
3. Cold winter deserts: They are also known as semi-arid deserts. The Great Basin, the Colorado Plateau, and the Red desert are all cold winter deserts.
4. Polar deserts: They are found in the Antarctic and Arctic regions.
OK so basically they use binary fission to into two halves producing two new cells.
Answer:
Because there is barely any sunlight (warmt)
