(SC.912.N.1.1) An osmosis investigation was conducted using 20 chicken eggs to represent cells with semipermeable membranes. The eggs were first soaked in vinegar to dissolve the shell. The eggs were then transferred to corn syrup for 24 hours and then to distilled water for 24 hours.

The table below shows the average mass of the eggs at each step of the investigation. Based on this experiment, which of the following should be inferred about cells with semipermeable membranes?

Water enters the cell when placed in environments of high water concentration.

(SC.912.L.17.5) The number of pythons found throughout Everglades National Park has increased in recent years. These huge snakes are not native to Florida and are believed to have been released into the wild by pet owners. Wildlife biologists have initiated attempts to capture and remove these pythons. Which statement best explains the biologists’ reason for removing these pythons from the Everglades?

The pythons could prey on native organisms and cause native populations to decline.

In Siamese cats, the fur on the ears, paws, tail, and face is usually black or brown, while the rest of the body fur is almost white. If a Siamese cat is kept indoors where it is warm, it may grow fur that is almost white on the ears, paws, tail, and face, while a Siamese cat that stays outside where it is cold, will grow fur that is quite dark on these areas. The best explanation for these changes in fur color is that ___.

the gene for fur color is modified by interactions with the environment

the location of pigment-producing cells determines the DNA code of the genes

skin cells that produce pigments have a higher mutation rate than other cells
