True/False
andrezito [222]

Answer:

This is true

These are the 3 factors:

  • Planet's Distance To Sun
  • Planet's Reflectivity
  • Planets Surface (Through Greenhouse Effect)

The thickness of the atmosphere, seems to be part of it, and I belive that is true, as it plays a role in temperature, determening wether if it can help with how warm or cold a planet is.

A planet's distance from the sun definitly plays a role, becuase depending on how far or close a planet is to the sun, the warmer it can be.

Planet's Surface goes through the process of greenhouse effect, causing a(n) planet to be able to get hotter

  • Planaria is a genus of planarians in the family Planariidae.
  • When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual.
  • Currently the genus Planaria is defined as freshwater triclads with oviducts that unite to form a common oviduct without embracing the bursa copulatrix and with an adenodactyl present in the male atrium.
  • The testes occur along the whole body.
  • Planaria originally have habitats in dark, murky water which results in such sensitivity .
  • They are also sensitive to other stimuli such as chemical gradients, vibration, magnetic and electric fields .
  • Their central nervous system includes the anterior (head, brain and eyes) and middle (abdominal trunk and pharynx).
