Aregion experiences frequent landslides from heavy rains. how can the local residents lower the frequency of landslides in the region?
a start contour plowing on the slopes where landslides happen.
b plant vegetation on the slopes that experience landsides.
c encourage deforestation in the regions that haven’t suffered landslides.
d divert water so it flows into the affected region.
e reduce the slopes where landslides occur.

There are two possible effective choices

A. Start contour plowing on the slopes where landslides happen.

E. Reduce the slopes where landslides occur.

Explanation:

Plowing can help flow water through the slopes instead of it all building up in one area all at once. But reducing the slopes can slow landslides due to the smaller incline, but will not completely get rid of them.

the cytokine-activated janus kinase (jak)-signal transducer and activator of transcription (stat) pathway has an important role in the control of immune responses. dysregulation of jak-stat signaling is associated with various immune disorders.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
