Astronomers use light years to measure distances in space because space is so massive and distances so far that conventional numbering is inadequate and unmanageable. One light year is a distance measurement equivalent to six trillion miles.
Explanation:
Primary succession starts off with the modification of a previously unoccupied area along with increasing variation- this occurs in barren areas devoid of life like sand dunes, and lava flows. Communities in a primary succession include:
-barren rock
-bacteria and fungi
-mosses and lichen
Further Explanation:
Succession involves small scale changes within a community that occur repeatedly over the life of that community.
Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:
- colonizing species exploiting uninhabited areas (Primary succession)
- becoming a habitable and increasingly complex community
- there is increased diversity of organisms (Secondary)
The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.
However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.

I think the nurse should asses the blood pressure, skin color, and moisture. Sinus bradycardia may be defined as a sinus rhythm with resting heart rate of 60 beats per minute or less. However few patients become symptomatic until their heart rate drops to less than 50 beats per minute. Intervention for sinuses bradycardia should be based on assessment of the clients condition. The patient may remain asymptomatic, the nurse may choose to increase the IV flow rate, administer atropine, or notify the Rapid Response Team depending on the severity of the symptoms.
A scientific theory changes when there is more information available about what the theory covers.
