Selectively Permeable means that some things can move across the cell membrane while others cannot.
Here is a sentence: Because of the selectively permeable membrane, the germs were kept out while the food went in.
Answer:
d = 1.53 g/mL
Object will sink into water
Explanation:
Given data:
Mass of object = 14.8 g
Initial volume of water = 25.0 mL
Final volume after adding object = 34.7 mL
Density of object = ?
Density of water = 1.00 g/mL
Solution:
Volume of object = Total volume - volume of water
Volume of object = 34.7 mL - 25.0 mL
Volume of object = 9.7 mL
Density of object;
d = mass/volume
d = 14.8 g / 9.7 mL
d = 1.53 g/mL
The density of water is 1.00 g/mL which means object is heavier than water thus object will sink into the water. The object with density less than water are float in it.

Answer: Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment. If each of the two atoms shares an electron with the other atom nearly equally, the bond is called covalent.
