Sister chromatids of a duplicated chromosome are joined by cohesions. Assembling tubulins to form spindle microtubules
Prophase. Prophase, the first stage of mitosis, sees the recruitment of condensin and the start of the condensation process that lasts until metaphase. The chromosomes decrease and thicken during prophase. Chromatids split across the centromere and migrate to opposing poles during anaphase. Telophase: Following the reorganization of nuclear envelopes surrounding each cluster of chromosomes, two nuclei are created by cohesion. Prophase, Metaphase, Anaphase, & Telophase are the four fundamental stages of mitosis by cohesions. Cytokinesis, the process of splitting the contents of the cell to create two new cells, begins in either anaphase or telophase and occurs in this exact sequential manner.

The squirrels are attuned in their brains to understand that owls are a threat because it is a predator. This is visual stimuli that evolved over many years to elicit a conditioned response. This is an innate behavior (meaning that it has been pre-programmed into an animal's genes) and offspring are naturally born with it.
