28. Postembryonic period - direct development and metamorphosis, raging and death.

Question 1

Postembryonic period:

• starts with birth or hatching and ends with death
• growth and development using substances from the environment
• the development can be direct or indirect (metamorphosis)

Answer 1

Question 2

Metamorphosis - development involving a conspicuous and relatively abrupt change in the animal’s body structure through cell growth and differentiation

Answer 2

Metamorphosis - development involving a conspicuous and relatively abrupt change in the animal’s body structure through cell growth and differentiation

Question 3

Incomplete or partial metamorphosis:

• hemimetabolous development
• immature stages are called nymphs

Complete metamorphosis:

• motometabolous development
• including a pupal or resting stage between the larval about forms

Answer 3

Incomplete or partial metamorphosis:

• hemimetabolous development

Complete metamorphosis:

• motometabolous development
• including a pupal or resting stage between the larval about forms

Question 4

Aging - A progressive deterioration of physiological function hypothesis:

• decreased function of the immune system
• errors in replication
• change in colloidal system of cells (decrease of metabolic processes)

Answer 4

Aging - A progressive deterioration of physiological function hypothesis:

• decreased function of the immune system
• errors in replication
• change in colloidal system of cells (decrease of metabolic processes)

Question 5

Death - end of individual development

Clinical death - cessation of life support functions (breathing and circulation) Biological (brain) death: electrical activity of the brain decreases

Answer 5

Death - end of individual development

Clinical death - cessation of life support functions (breathing and circulation) Biological (brain) death: electrical activity of the brain decreases
