I believe, from a population that is uniformly distributed through its habitat a biologist can infer that it has reached it's carrying capacity. Population distribution describes how the individuals are distributed, or spread through out their habitat. Population size and population measure are important measures of the population. When the population is uniformly distributed, it means that they are evenly spaced over the area they occupy, thus the individuals compete for a scarce environmental resources, such as water in a desert.

Prophase is the right answer
Water and Carbon dioxide combine during photosynthesis to make glucose and oxygen.
