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.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
