Do organisms with higher fitness mean that they have survive to an advanced age? why or why not?

No. Having a higher fitness in biology means surviving  to reproductive age, finding a mate, and producing offspring. The more offspring an organism produces during its lifetime, the greater its biological fitness, regardless of how long the organism lives. If an organsim produces 5 offspring during their lifetime and dies at an early age, they would still be considered more fit than an organism that lived a long life and did not produce any offspring.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
