c disruption of animal habitats

Explanation:

One of the likely effect of large scale infrastructural development is that it can lead to the disruption of animal habitats.

To develop new infrastructure, new areas have to be cleared to install the facilities and this can lead into encroachment of animal habitats.

  • Oil drilling projects are capital intensive ventures undertaken by exploration and production companies.
  • The oil is usually found in geologic formations deep within the earth crust.
  • To access this fuel, large drilling ventures must be undertaken in order to accommodate to technology and man power.
  • New areas have to cleared and this can push the habitat of organisms backward

Reil [10]

Naphthol AS-D chloroacetate esterase (specific) is usually positive in <u>Granulocytic</u> cells, and alpha naphthyl acetate esterase (nonspecific)is useful for identifying blast cells of <u>monocytic</u> lineage.

  • White blood cells known as granulocytes have tiny granules. Proteins are present in these granules.
  • Granulocytes can be classified as neutrophils, eosinophils, or basophils. The body uses granulocytes, particularly neutrophils, to fight bacterial infections.
  • A monocyte is a subtype of phagocyte and a type of white blood cell.
  • The role of the monocyte-macrophage cell lineage in acute and chronic allograft immunopathology is becoming more widely acknowledged.
  • It is linked to lower graft performance and survival when this lineage of cells predominates in tissue that is rejecting an allograft.
