The answer is Body temperature
Circadian rhythm will regulate the daily circle of an organism. There is many biological aspect that could be regulated such as the hormone secretion, blood sugar, body temperature, and sleepiness. The migration of birds would be happen annually, not daily. The female menstrual cycle would be happened monthly too.
Mirror neurons are activated by performing an action or seeing another perform the action. They were found by chance during experiments with monkeys, when researchers discovered that the same neurons that fired while performing a behavior also fired while observing the behavior. Mirror neurons have been linked to motor skill development, imitating another's behavior, feeling empathy for another, understanding or comprehending social behavior, and language development. Answer for E2020
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.
