  - water level above some arbitrary point in the river and is commonly measured in feet
* last for few weeks
  - months

* measure of discharge.
* occur during third years
* refers to the extent of the cancer
  - extent, or the size, of the cancer
  - spread of the cancer
  - tumor's size and whether the cancer has spread to other organs
* span million years
+ Child development, Child Development Theories, Psychocosocial Theory
  * The ego was important because it lets children become an individual and add to society. Erikson ended up with eight stages in his theory. Every stage has a problem between two different feelings. A child's personality is shaped by how they fix each problem.

### period | stage:

Embryonic stage
* is where product is developed and launched and has yet to get widespread acceptance.
* last for weeks.

Immature stage
* are aquatic with larvae and pupae usually attached to submerged substrates
  - important as food for small fish
* develop as a parasite of earthworms.
* vary in color from black for very small nymphs to green for larger nymphs.

### period | stage:

Larval stage
* Some larval stages have legs.
* are aquatic, benthic, sedentary or sessile
  - found in the open water of bays and estuaries
  - maggots which crawl on the leaf surface in search of aphid prey
* can most likely be found at shallower depths, then later move to deeper waters.
* concentrate on feeding and growth.
* develop and reproduce in the internal organs of the snail.
* extend upto three months and the pupal period for nearly three months.
* feed on the roots and tubers of plants.
* is characterized by soft, elongated body with bumps on the skin
  - the longest stage in development of the Hercules beetle
* last from few months
* serve as food for fish in the aquatic habitat.

Life stage
* All life stages are capable of causing plant injury.
* All life stages are present during the whole year
  - through the growing season
  - can exist simultaneously as generations overlap
  - feed on blood
  - have chewing mouthparts
  - occur together on the undersurface of leaves on sycamore, ash and hickory
  - remain in the soil, feeding at or near root tips

Nymphal stage
* are similar but lack fully developed wings
  - yellow and wingless
* resemble adult earwigs in shape but have reduced wings and cerci.

Prophase
* occupies over half of mitosis.
* sets in as cell cycle factors operating in regulating cell division events are ready to go.

Tumor stage
* is clearly important in anticipating the clinical course of a given patient's disease.
* refers to how advanced the tumor is in the entire body.
