Answer:
The comparatively fast evolution of various species from a single common ancestor is known as adaptive radiation. It usually takes place when an organism enters a novel region and distinct traits influence its survival. The island chain offers suitable conditions for adaptive radiation to take place as when an organism of a certain species comes to an island together and get disperse all through the chain, and each of these organisms getting settle into distinct niches and exploiting various food resources in order to minimize the competition, thus, resulting into adaptive radiation.
The three germ layers are the endoderm, the ectoderm, and the mesoderm. Cells in each germ layer differentiate into tissues and embryonic organs. The ectoderm gives rise to the nervous system and the epidermis, among other tissues. The mesoderm gives rise to the muscle cells and connective tissue in the body.
Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.
Photic zone
Explanation:
The photic zone is the zone where light reaches. It extends from the region of the continental shelf downward to the continental slope.
There is rich biodiversity in this region due to the presence of light for the process of photosynthesis.
The photic zone is the closest part of the ocean to land. This region marks the boundary between the continental crust and oceanic crust.
A resort will be most suitable in this region because the water is shallow.

This is because some of the trisomies (one extra chromosome, three instead of two) are fatal, births cannot survive.
Theoretically, trisomies can occur with any chromosome, but often result in miscarriage.
The types of autosomal trisomy that survive to birth in humans are:
Trisomy 8 or Warkany syndrome 2
Trisomy 9
Trisomy 13 or Patau syndrome
Trisomy 18 or Edwards syndrom
Trisomy 21 or Down syndrome.
