Answer:
The smaller object will move at 30 m/s
Explanation:
From the principle of conservation of linear momentum,
Momentum of objects before collision = momentum of objects after collision.
where 
are the masses and velocities of the objects 1 and 2 respectively before collision.
Hence, the object will move at 30 m/s
Answer:
Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do.
Explanation:
Cell function depends on cell structure because different cell types have different structures, as well as functions. Prokaryotic cells have no nucleus, and they are unicellular. Eukaryotic cells have a nucleus and are multi-cellular. Both have organelles. Hope this helped :)
