Answer:
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.
Answer:
Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called the stomata. The lower part of the leaf has loose-fitting cells, to allow carbon dioxide to reach the other cells in the leaf.
Explanation:
To establish causation sociology, there are three key factors namely correlation, time order and ruling out alternative explanations. correlation gives the difference between the alternatives to be considered, time order gives the occurrence of events chronologically, finally, the ruling out alternative explanation gives one the chance to get the best alternative
Answer:
Due to average population density.
Explanation:
The population density of Canada is the average population density of the whole Canada whereas the population density of city of Montreal refers to the population density of one city only. There are some regions in the country usually in the rural areas where population density is very low while on the other hand, the population density of cities are very high due to more job opportunities so that's why the population density of Canada is lower as compared to the city of Montreal.
