### condition:

Environmental condition
* Most environmental conditions affect behavior
  - evaporation
  - gene expression
  - survival
  - water evaporation
* Most environmental conditions are experienced by individuals
  - mothers
  - change over time
* Most environmental conditions exist in countries
  - other countries
  - require excretion
* Some environmental conditions affect ability
  - fitnesses
  - pathogen replication
  - kill plants
  - lead to death
  - limit crop production
  - stimulate broodiness
* add to the irritation of a toxicant.
* affect areas
  - development
  - performance
  - the survival and behaviour of plants and animals
* are conditions
  - critical in determining the frequency of indirect transmission
  - extremely important in disease development
  - factors in fatigue and illness
  - important for the development of the disease
  - one of the factors contributing to pesticide spray drift
* are the key factor in hybrid-herbicide interactions
  - variety-herbicide interactions
* become more hospitable for humans and larger mammals.
* can affect grain composition
  - group size and composition
  - the yield of sugar
* can cause two major problems with regard to evaporation
  - waste
  - influence reaction rate and therefore how fast pesticides break down
  - modify the appearance of plants
* change in time and space
* determine migration behavior
  - variation
  - which mode of nutrition they use
* enable certain species of plants and animals to colonize habitat borders.
* have a direct correlation on public health issues and the economy.
* have an impact on many living organisms
  - important influence on the development of spider mite populations
  - major effects on the health, opportunity, and security of poor people
  - more influence on watering than any other factor
* impact health.
* influence life history strategies
  - the process of flowering and setting of pods
* limit growth.
* permit the maintenance and transfer of pathogenic foodborne microorganisms.
* play a key role in estimating stock abundance
  - large role in the value of a trait
  - an important role in the establishment of many natural enemies
* promote development.
* require enhance excretion

### condition:

Erection
* are a reaction to a sexual signal
  - structures
  - the result of a neurovascular event triggered by cognitive or tactile stimulation
* begins when a man receives sensory and mental stimulation.
* begins with sensory and mental stimulation
  - or mental stimulation, or both
* bridge that connects people.
* demonstrate that the nerves to the penis are normal.
* is caused during arousal by more blood flowing into the penis than flows out
  - construction
  - essentially a vascular phenomenon which is under neural control
  - in with teens love having sex
* occur in males of all ages, including babies and old men
  - response to stimulation
  - when the penis gets stiff and hard - sometimes for no reason
* occurs after a period or arousal
  - due to the action of specific nerves known as the nervi erigentes
  - when pellet is absorbed
* occurs when the blood flow to the penis increases when a man becomes sexually aroused
  - spongy tissues of the penis are engorged with blood
* parasympathetic function.
* start in the mind.
