Answer:
C. Age of Mammals
Explanation:
Cenozoic is derived from Greek word meaning NEW LIFE. The Cenozoic Era witnessed the disappearance of Dinosaurs which made Mammals to thrive and giving a new life to mammals. During this early stage as new life is beginning, majority of the animal species are relatively small comprising of the small mammals, birds, reptiles and amphibians.
Ratio of osmosis is calculated via equation rate = (change in mass)/(time), which means that
Ratio of osmosis in cucumber is: (12-14 g) / 5 min (300 s)= -0.006 g/s
Percentage change in mass would be= (14 – 12) ÷ 12 × 100 = 2 ÷ 12 × 100 = +17%
The effect is that Frank's 10% sucrose bag will be heavier than that of others.
<h3>Osmosis</h3>
Water molecules move from the region of lower solute concentration to the region of higher solute concentration.
Thus, water will continue to enter into a 10% sucrose bad dropped in a beaker of water until an equilibrium is established between the 2 media.
This means that the longer the bag stays in the beater containing water, the more the water will enter, and the heavier it will weigh.
