Which of these regions is most likely to develop into the Drosophilia's head? The Drosophila embryo is divided into 5 parts marked from A to E. These parts are arranged in the order of decreasing concentrations of the bicoid protein. Letter A marks a part with the highest concentration; letter E marks a part with the lowest concentration.

Part-A will lead toward the head development of Drosophila.

Explanation:

A morphogen is a substance that governs the pattern of tissue development in the process of morphogenesis or pattern formation, Pattern formation is one of the core processes in the development of Drosophila's body. Bicoid was the first protein demonstrated to act as a morphogen. Bicoid is a gene whose protein concentration gradient patterns the anterior-posterior (A-P) axis during Drosophila embryogenesis. Although Bicoid is important for the development of Drosophila's head. Bicoid concentration is high in the anterior side or in part-A of the Drosophila that will become the head. Bicoid concentration is low at the posterior side or part-E of the Drosophila that will become the tail.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion

b. lithosphere, asthenosphere, mesosphere   is the answer most likely
