What fats are called saturated?
a). fats that contain no double bonds in fatty acid chains
b). fats that have some double bonds in fatty acid chains
c). fats that have triple bonds in fatty acid chains
d). none of the above

A

Explanation:

Fats are made up of several carbon chains – of different lengths- per molecule. An example is triglyceride with 3 fatty acids connected to glycerol.  When several chains without double bonds are brought together – they attract each other tightly through the numerous hydrogen bonds they share between the chains. Presence of double bonds in the chains  form kinks within the chains and disrupt the hydrogen bonds shared between chains. It is therefore common that solid fats are saturated fats because they bond so tightly they require higher temperatures to get to meting point as compared to unsaturated fats.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
