A) spines
A herbivore, or a plant eating animal, will be much less likely to go after a plant that is covered in spines. Spines make the plant painful and difficult to eat.
Answer:
temperature
Explanation:
Temperature is the only factor that affects the solubility of all solutes whether they are solid, liquid or gaseous.
Solubility of solutes is temperature dependent.
When one substance dissolves in another, they are said to be soluble in it.
Pressure as a factor only affects the dissolution of gases.
Volume and number of moles do not affect solubility
Explanation:
No of molecules=0.500×6.023×10²³=3.011×10²³ molecules
Answer:
Let x moles of silicon contains 2.8x10^24 atoms. 6.02x10^23 atoms are present in 1 mole of Si. Therefore 2.80x10^24 atoms are present in = 2.8x10^24/6.02x10^23 = 4.65 moles of Si.
