Step-by-step explanation:
<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:
Step-by-step explanation:
(a)
For the quadratic equation of the form ,
The discriminant is given as:
Simplifying the given quadratic equation:
[(x-7)^2] - 62 = 19
∴ (x^2) - 14x + 49 = 81
∴ (x^2) - 14x - 32 = 0
Comparing with the standard form of quadratic equation:
a = 1; b = -14; c = -32
∴ Discriminant = (b^2) - 4ac = 196 + 128 = 324
Since Discriminant > 0,
The roots will be real and distinct.
(b)
This equation can be factored as:
(x - 16)(x + 2) = 0;
∴ x = 16 ; x = -2, are the two roots of the equation.
