5. Dentritic cells
They are also known as <em>Langerhans cells</em>. They can be found in two layers of the epidermis: the stratum spinosm; and stratum granulosm. They are what you call macrophages that come from the bone marrow. They serve as immune cells that provide protection against toxins, microbes and other pathogens that try to penetrate the skin.

How does contour plowing in farming help to prevent pollution?
wel

D) Contour plowing is used to reduce erosion and sediment pollution.

Explanation:

Contour plowing in farming helps to prevent pollution by reducing surface erosion of topsoil and preventing sediment pollution.

Contour plowing is a farming technique in which crops are planted along the slopes of hills or contoured areas.

  • The rate at which rain water and precipitation moves along slope terrain is very fast.
  • This causes the washing off of the the topsoil on hills to eroded very fast.
  • Contour plowing breaks the slope and farming is done along movement on the contour.
  • This prevents topsoil erosion.
  • It also prevents sediment pollution in nearby streams and water bodies that are located around the valley at the base of the hill.
