Final answer:
In the context of migration, planning involves initial assessments, preparation entails gathering resources and physiological readiness, and migration is the act of moving. The G₁ phase of the cell cycle is for preparing DNA synthesis, and propulsion is a digestive process occurring in the alimentary canal.
Step-by-step explanation:
Migratory Phases and Cellular Processes
During a migration, the activities you mentioned fall into the following phases:
- a) Planning: This involves the initial assessments and strategizing that occur before any action is taken. It can involve physiological changes and behavioral changes as organisms anticipate seasonal changes.
- b) Preparation: This phase includes the process of gathering resources, physiological preparation, and packing, if referring to human migration. This is when organisms or humans prepare for the actual act of migration.
- c) Migration: This is the execution phase where organisms or humans physically relocate from one place to another.
- d) Not part of the migration process: This option can be selected if any activity listed does not fit within the migration context.
Regarding the cellular process, the phase b) G₁ is characterized by preparation for DNA synthesis, as cells prepare to enter the S phase where DNA is replicated.
In the context of human digestion, the process of b) propulsion occurs throughout most of the alimentary canal.
