parts per million (ppm)
This is equivalent to g of lead for each million grams of blood
Numerically, it can be represented as -

Lead in g of blood grams
Answer:
Extrinsic regulatory mechanisms are external and depend on the firing of some factor outside the population itself. Among them are interspecific competition, food and space restrictions, very strong climatic variations, weathering and inharmonious relationships with other populations (parasitism and predatism).
Good examples of interspecific competition appear when rabbits, caves, rats compete for the same plant, or different fish and birds, such as the heron, vie for the same species of smaller fish. This is because these different species keep their populations in the same ecological niche. Competition is often so strong that some species eventually, as one example of an extrinsic homeostatic mechanism overriding an intrinsic homeostatic process is their disappearance or migration to other regions.
In this competition, the presence of adaptations among individuals in the population that promote better food search, speed, vision, and others can make the difference between elimination and survival.
The correct option is E.
The Ripariana zone is an interface between land and a body of water, especially rivers and streams. The riparian zone is home to many animals which move between land and water. The riparian zone provides many recreational and environmental benefits to streams, underground water and downstream land areas. <span />
