The mass of a cylinder of beetroot was 2.5 g. If its final
mass was 2.7 g, what was the
increase in mass in per cent?
Answer: The percent increase in the mass of cylinder of beetroot is 8%.
Explanation:
To calculate the percent increase in the mass of cylinder, we use the equation:
[tex]\%\text{ increase in mass}=\frac{\text{Final mass - Initial mass}}{\text{Initial mass}}\times 100[/tex]
We are given:
Final mass of the cylinder = 2.7 g
Initial mass of the cylinder = 2.5 g
Putting values in above equation, we get:
[tex]\%\text{ increase in mass}=\frac{2.7-2.5}{2.5}\times 100\\\\\%\text{ increase in mass}=8\%[/tex]
Hence, the percent increase in the mass of cylinder of beetroot is 8%.

how does a beneficial trait increases an organism's survival and potential reproductive success.
Answer:
This cumbersome trait significantly decreases the male's chances of survival. ... natural selection: that is, that organisms better adapted to their environment would benefit from ... the individual's reproductive success, even at the expense of their survival (Darwin 1871). ... A successful male can potentially sire many offspring.
Explanation:
The beneficial trait increase the survival and potential reproductive success of the organism as they help organism to thrive in their unfavorable changing environment.
Natural selectionThe natural selection can be defined as the differential survival and reproduction of those organisms which have beneficial traits over others.For example, the color change in chameleon helps them to remain undetected from predator population as well as from prey so it helps in increase in rate of survival of chameleon also helps them to reproduce and increase in number.Hence, beneficial traits increase the rate of survival and reproduction of organisms.
