• These are factors in the environment that influences the behavior of an organism.

  Stimulus
• It is an abnormal condition where there is an excessive production of growth hormone by the pituitary gland.

  Gigantism
• Part of neuron or nerve cell that carry impulses away from the cell body.

  Axon

  Central nervous system
• Endocrine gland responsible for producing insulin and glucagon in the body.

  Pancreas
• It connects the central nervous system to the organs and limbs.

  Peripheral nervous system
• Part of the nerve cell that carries impulses going toward the cell body.

  Dendrites
• It is considered as the master of all glands.

  Pituitary gland
• Endocrine gland that is responsible for preparing the body for action by releasing adrenaline.

  Adrenal gland
• It is a hormonal imbalance that results to decrease release of growth hormone in the body.

• It regulates body metabolism and causes storage of calcium in bones.

  Thyroid Gland
• These are organisms produced asexually from a single parent.

  Clone
• It is considered as the basic and functional unit of the nervous system.

  Nerve Cell
• These are changes in the genetic make up resulting in a new characteristic inherited by the offspring.

  Mutation
• It is a process by which a molecule of DNA is being copied.

  DNA replication
• These are chemical substance produced in the body that controls and regulates the activity of cells or organs.

  Hormone
• These are organisms whose genetic information has been altered.

  Genetically Modified Organism
• The male reproductive organ responsible in producing androgen and testosterone.

• It occurs when the last member of a species dies.

  Extinction
• It refers to species in which the number of individuals falls so low that extinction is possible.

  Endangered species
• These are the factors that control the growth of a population.

  Limiting factors
• It refers to the variety of life in a given area.

  Biodiversity
• It is the total number of organisms belonging to the same species in a particular environment.
