B amniotic eggs which is one of the similarities they share with birds (one of the many similarities and cause birds and reptiles to be on the same branch)
Answer:
It is diffusion
Explanation:
The dye is moving through the paper without the use of energy and is going from areas of high concentration to areas of low concentration
By using the legend below the diagram, you can assume that Phase 1 indicates that meiosis has occurred because of the color of the arrow. The dark gray indicates haploid, and haploid is the result of meiosis. Diploid is the result of mitosis.
Another indication is the presence of sex cells or gametes in Phase 1. Meiosis produces gametes and in phase 1, you can see that egg cells and sperm cells were produced.
It is present at high concentration at the anterior end and low concentration at the posterior end.
Gene bicoid (and its product-bicoid protein) organizes anterior development in Drosophila.
During oogenesis, bicoid mRNA is actively localized to the anterior of the Drosophila egg.
Bicoid genes together with Hunchback genes are the maternal effect genes and that are most important for patterning of anterior parts of the Drosophila embryo such as head and thorax.
