Reason why leopard and lion can't breed yet they belong same genus

Leopard and lion both have 38 chromosomes, so chromosomal incompatibility is not an obvious barrier. Wild occurrences of this crossbreeding have been reported from hunting derived pelts which show the typical hybrid blending but are presumably rare due to ecological and behavioral barriers.

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
