Q: The difference between protostomes and deuterostomes is
A: The major difference between protostomes and deuterostomes are how they develop in the early embryo stages. In protostomes the mouth opening is the first to be formed later followed by the anus. [ In deuterostomes the anus forms first followed by the mouth. This all occurs in the gastrulation stage. ]

User: A coelom is _____.

User: If the ordinate is three more than twice the abscissa and x {-1, 0, -}, which of the following sets of ordered pairs satisfies the given conditions

Weegy: {(-1, 1), (0, 3), (-1/3, 7/3)} is the set of ordered that pairs satisfies the given conditions.

User: Given: x + y = 6. If x {-15, -6, -1}, then which of the following sets of ordered pairs are solutions?

Weegy: Graph the equation x-y=6 Answer: First rewrite the equation in the form, y = mx + c That is ..... y = x-6 Now give arbitrary values for x and hence find the corresponding values of y That is... When, x = 6, y = 6-6 = 0 When, x = 5, [ y = 6-5 = 1 When, x = 4 y = 6-4 = 2 when x = 3, y = 6-3 = 3 and so on The you will get the coordinators as follows... (6,0), (5,1), (4,2), (3,3) and so on ]

User: Given: 2x + 3y = 6. What is the y-intercept?

Weegy: Sub x = 0 into the equation 2(0) + 3y = 12 y = 4. Therefore the y-intercept is 4
