• Cell Division (A80): One of the phases of the cell cycle. Mitosis and Cytokinesis.

• Nucleus (A20): The structure that the genetic material is stored in. In the center of the cell.

DNA (A74): A chemical that contains information for an organism's growth and functions.

• Cell Cycle (A80): Normal sequence of development and division of a cell.

• Chromosome (A75): DNA is wrapped around proteins like thread around a spool and compacted into structures called chromosomes.

Explain how an organism can maintain homeostasis.
Organisms use energy to distribute materials throughout their bodies, and then transport and eliminate the wastes produced by their bodies. The sense and respond to certain stimuli, defend themselves from predators, and grow/reproduce.

11. Explain how different defensive behaviors of animals help them to survive (ex: tightening of quills on a porcupine, making the body larger).
Defensive behaviors such as making the body appear to be bigger help an animal survive by scaring off prey. When an animal makes their body appear to be larger, or tighten quills, or make loud noises the predator animals get spooked and leave them alone.

12. Describe the behavioral cycles of organisms (hibernation, migration, dormancy).
Hibernation: Hibernation is a sleeping state, which lasts for long periods of time. ANimals like bears, eat lots before entering hibernation so that their body has enough fuel to live. They enter hibernation during winter, because during winter there is no food for them to eat, and if there is it is very scarce.
Migration: Animals migrate during certain times of the year, for reasons like food, temperature, or breeding. One example of migration is the migration of Canadian Geese. They migrate to the south in large numbers, for the warmer climate. Once it gets warmer, they begin returning to colder …show more content…

This helps organisms to conserve energy.

13. Compare symbiotic and competitive relationships within the environment (mutualism, predation, commensalism, parasitism, cooperation).
In all symbiotic relationships, one of the species involved in benefited. In Mutualism, both are benefited, in Parasitism one is harmed by the other’s gain, is commensalism one is not affected by the other’s gain. In a Cooperative relationship, both are working together to achieve a common goal. In Predation, one organism is preyed upon by another, who will most likely use the organism for food.

14. Describe how human introduced invasive plant and animal species can harm ecosystems.
A species that is introduced to an ecosystem by humans can harm ecosystems in many ways. Animals that are introduced into a new area, could hunt a main food source for some animals, causing that population to decrease. Plants could be poisonous, or need to feed off of other plants. Species introduced into an ecosystem by humans through off the natural balance of the wildlife.
