Question

Define the following terms :

a) Cold blooded animals .
b)Bilateral symmetry
c)Radial symmetry

Answer 1

 a) Cold blooded animals :

they can change their body temperature anytime according to the outer environment.
so they dont maintain a constant or a regular body temperature throughout their life.

b)Bilateral symmetry:
when you cut a body in any one direction where you see both the parts equal and same ,it is called as bilateral symmetry.

ex: we humans show bilateral symmetry.


c)Radial symmetry:
 if you try cutting a body into many parts in any direction, all the parts look the same.this is called radial symmetry.

ex: starfishes show  radial symmetry.
