Wegener proposed the hypothesis of continental drift, which suggested that continents are in constant motion on the surface of Earth. Over time Pangaea began breaking apart, and the continents slowly moved to their present positions.
<h3>What is Continental Drift ?</h3>
The theory of continental drift is most associated with the scientist Alfred Wegener.
- Wegener's continental drift theory introduced the idea of moving continents to geoscience. He proposed that Earth (opens in new tab) must have once been a single supercontinent before breaking up to form several different continents.
- The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones' locations.

Answer: For decreased chances of rejection
Explanation:
The three higly polymorphic MHC 1 genes in human beings are HLA-A, HLA-B and HLA-C.
These determine the compatibility of the organ or tissue in the recipient's body each by the help of many alleles that segregates in a population.
There are very less chances that a random chosen donor will match the a recipient six allele genotype.
This is the reason parent may be the best donor for organ transplantation or tissue transplantation.
During acclimatization over a few days to weeks, the body produces more red blood cells to counteract the lower oxygen saturation in blood in high altitudes. Full adaptation to high altitude is achieved when the increase of red blood cells reaches a plateau and stops.Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). ... At the beginning of exercise, your body removes the parasympathetic stimulation, which enables the heart rate to gradually increase.
D)all of them
So the similarity of the planets and the dwarf planets are they are both mostly round because they have sufficient gravity to flatten their own surfaces into a sphere. The differences are that planets are big enough to clear the whole region of space where they orbit the sun whereas dwarf planets do not.
