Climates are determined mostly by precipitation and temperature. Climates are determined mostly by temperature. Climates vary from year to year and organisms adapt to the variation in climate. The earth has many climates. You are interested in the evolution of dioecy from hermaphroditism using a phylogenetic approach.
Dioecious plants have male and female flowers on each individual.
Scientists want to figure out how to regenerate the growth of axon after injury. They called this protein the NOGO protein. To prove that this protein did block axonal outgrowth, they made antibodies against the protein. In a petri dish in the presence of NOGO antibodies and positive factors the experimenters observed good axonal outgrowth. However when the experimenters did a spinal transection in a mouse, and injected NOGO antibodies, the mouse could only poorly move its legs.
