When you say small dissolved particles I am going to say endocytosis.
For any terrestrial planet in the solar system, the core would be the densest layer, and the crust would be the least dense layer.
The body temperature of the mammal will be higher than that of the reptile. this is because the mammal body temperature does not depend on its environmental temperature while a reptile does not have a stable body temperature and depend on the temperature of its environment.
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.
