Answer:
Explanation:
The host's immune response to the transplanted graft, which is commonly exhibited as pericapsular fibrotic overgrowth (PFO), is one of the key causes of defective encapsulated islets in (PFO).PFO creates a barrier upon this capsule surface that inhibits and impedes oxygen and nutrients from entering, resulting in islet cell deprivation, hypoxia, and/or death. This host immune response was missing under in vitro circumstances, which explains why glucose sensing and insulin release were more efficient than in vivo circumstances. Nonetheless, utilizing nanoporous encapsulation or modifying the microcapsular shape and geometry can solve these issues.

The answer is terracing.
Terracing is a type of landscaping characteristic for steep slopes and mountains. Graduated terraces are used to farm on this kind of terrain to reduce erosion. This way crops are planted on graduated level areas and not on steep terrain, and risk of surface runoff is reduced.
The number of covalent bond an element can form depends on the number of electrons it has in its outermost shell (valence electrons). Carbon has four valence electrons, therefore, it can form maximum of four covalent bonds in an organic compound.
