Delayed phase preference.
Its when teenagers begin to stay up later on average about 2 hours later. It is initially caused by melatonin; its a chemical that makes us sleepy but in teenage melatonin levels rise about 2 hours later than in pre-teens, so teenagers do not get sleepy. When combined with stimulus to stay awake tv, texting or surfing the web or whatever teenagers go to bed much later.

MA_775_DIABLO [31]

III only (floods and drought) is an example of density-independent factor affecting population growth.

<h3>WHAT IS DENSITY-INDEPENDENT FACTOR?</h3>

Certain factors affect the growth and multiplication of living organisms in populations. These factors can either be;

  1. Density-dependent
  2. Density-independent

Density-independent factors are those factors that are not dependent on the density of the population to affect them. These factors are usually physical factors of the environment like;

  • Disasters
  • Flood and drought
  • Earthquake etc.

Therefore, III only (floods and drought) is an example of density-independent factor affecting population growth.
