The Semi-fluid layer moves in circular movements based on the temperature and density of it's particles. When the particles become less dense, the semi-fluid rises. Once it reaches the bottom of the crust, the particles become dense, and go back to the inner core. Once it's at the inner core, the particles temperature heats up again and causes the circular movements to proceed.
Since you forgot to put capital letters i assume it's like this:
1)A <span>Cross between YyLl (heterozygous parent with dominant traits) and yyll (homozygous parent with recessive traits).
</span><span> 2)offspring YyLl: 400, Yyll: 100, yyLl: 100 and yyll: 400
</span>The recombinant offspring are allele combinations that are not directly inherited from the parents.
The parents combinations:<span>YyLl and yyll,
</span>The recombinant combinations: Yyll and yyLl
The other types are exacly like the parents so they are not recombinant.
answer: Yyll and yyLl
When you spin around, you lose balance because of fluid spinning around in the C) semicircular canals.
