Some diatoms are benthic and live on mud, seaweeds , and other surfaces . what type of adaptions to this particular habitat you expect them to have ?

Had to find that :/

Some of the diatoms are able to stay afloat and some of them lies at the bottom of the water bodies.

The can easily float because they have a large surface area and they can extend their body parts and makes them sink much slower.

Other types of the diatoms remains attached to the benthos and because they do not have appendages and they sink in the bottom of water.

Some of the diatoms that live on mud have the appendages for crawling.

the denominator has a very specific role.

after receiving a stimus, the sensory receptors send(s) signals to the appropriate area of the body.  

the must be sensory neurons.  

hope its .
