<span>A bilaterally symmetrical animal, like a lobster, fish, or human, can only be cut in one way to get equal halves. Bilateral symmetry leads to cephalization; that is, sensory organs and the brain get moved to the head end of the animal. This is good for predators, for chasing their prey, etc. But it may make it harder for them to detect animals going after them.

Answer:
6f + 3
Step-by-step explanation:
so in order to get a equation that is equivalent to 4f + f2 + 3 is you have to simplify the expression by adding numbers to numbers and variables to variables.
so we are going to add 4f and 2f together:
(4f + f2) + 3
And you get the expression:
6f + 3
I hope this helps you!!
