Terrestrial gastropod
* Most terrestrial gastropods are hermaphrodites.
* Some terrestrial gastropods conserve water.

### herons:

Blue heron
* Most blue herons adapt to habitats
  - wetland habitats
  - feed on insects
* Most blue herons have feathers
  - neck vertebrae
  - plumages
  - white plumages
  - live for years
  - nest in colonies
* Some blue herons live in aquatic habitats

### heterogeneous material indeed:

Interstellar dust
* Most interstellar dust is made of silicates, the same molecular materials as sand.
* absorbs and reddens light in a way that astronomers understand very well.
* acts in similar ways to dust in our planet's atmosphere.
* blocks visible light.
* heterogeneous material indeed.
* is an unknown
  - produced in the envelopes around red supergiant stars
  - the fine haze of smokelike particles which is distributed between the stars

Heterotroph
* All heterotrophs are Animalia.
* Most heterotrophs absorb food
  - are completely dependent on autotrophs for food
  - use energy
* Some heterotrophs eat autotrophs and use the energy in the autotroph's stored food.
* Some heterotrophs obtain food
  - nutrients
* are organisms.
* depend either directly or indirectly on autotrophs for nutrients and food energy.
* eat other plants, animals, and some eat remains of dead animals
  - ready - made complex organic food
  - to obtain energy from the breakdown of organic molecules in their food
* get organic molecules from other organisms.
* includes cell membranes
  - cells
  - corpi
  - cytoplasm
  - nuclei
  - plasma membranes
  - sections
  - vacuoles
* is an organism
* obtain the food molecules prepared by plants and other producers
  - their food from other organisms, living or dead
* survive by feeding on organic matter produced by or available in other organisms.

Hexane
* are very volatile.
* can be toxic by inhalation, ingestion, or absorption through the skin.
* deadly poison.
* has a six carbon chain and is nonpolar
  - no structures on it
