Answer:
An enzyme speeds up a chemical reaction in the cell, but it can only be used once.
Explanation:
The future of the Universe will be determined by the struggle between the momentum of its expansion and the pull of gravity. ... The vertical scale indicates the size of the Universe. For the next several billion years, the expansion of the Universe gradually slowed down due to the effects of gravity on matter.
So the equation is 2x^2 + 7x + 3 = 0, let’s factor this out: 2x^2 + 6x + x + 3 = 0, so 2x(x+3) + 1(x+3) = 0, so (2x+1)(x+3)=0, so x = -1/2 or -3
