Compare the arrangement of muscles in earthworms to amphioxus
mafiozo [28]

Earthworms have two muscles which is used in locomotion. Both muscles are circular and longitudinal (inner layer of the series of muscles). The diameter of the earthworms body is reduced when the circular muscles are contracted which makes them appear to be thin. The worm appears short when the longitudinal muscles contract thus, its length is reduced.

 

Amphioxus on the other hand,  have two unique muscle fiber types. This includes  deep fibers and smaller but mitochondria-rich superficial fibers. E<span>ach of which has its own innervation.</span>

motikmotik

<u>Answer:</u>

NaHCO_{3} is an inorganic compound.

<u>Solution:</u>

  1. Firstly, all the known definitions of organic compounds excludes Carbonic acid and it's salt from organic compounds except if 'C' is present in the cation.  
  2. Secondly, Sodium is a metal which organic compounds cannot posses as a compound.  
  3. Lastly, there is absence of C-H bond which is present in all the organic compounds.

Hence, we can conclude that NaHCO_{3}is an inorganic compound though there is presence of Carbon atom in it.

An element has a half-life of 30 years. If you start with 10g of this element, how many grams of this element would remain after
drek231 [11]

After two half-lives or 60 years, 7.5 g of the element will be left.

<u>Explanation:</u>

<u>Half-life:</u>

  • In simple words, Half-life can be defined as the amount of time needed for a quantity to fall to half its value as contained at the beginning of the time period.
  • In this problem the half-life of the element is thirty years, then after thirty years half of the sample would have decayed and half would be left as it is.
  • After thirty years (The first half-life ) 30 /2 = 15 g declines and 15 g remains disappeared.
  • And after another sixty years (The two half-lives) 15 /2 = 7.5 g declines and 7.5 g remains disappeared.
  • After two half-lives or 60 years, 7.5 g of the element will be left.
