In the early stages the embryos of four different species will look the same .For example, fish embryos and human embryos both have gill slits. In fish they develop into gills, but in humans they disappear before birth. That what makes them different.
Your answer would be A because none of the others make sense, Hope that helps!
Answer:
(x - 1)(x - 2)(x + 3)
Explanation:
f(x)=x3-7x+6 Since (a + b + c + d = 0), then f(1) = 0 --> one factor if (x - 1).
After division -->
f(x)=(x-1)(x2f2+x-6). The trinomial in parentheses can be factored.
Find 2 numbers knowing sum (1) and product (-6). They are -2 and 3.
Therefor, f(x)=(x-1)(x-2)(x+3)
