The hypothesis is an educated guess, so it cannot be used as a firm statement. In an experiment, the hypothesis is just a guideline that is tested & may or may not be true based on the results.
Hope that helps!
Answer:heh
Explanation:
Aluminium , mass no = no of proton + neutron = 27
atomic no = no of proton = 13
no of neutron = 27 - 13 = 14
Nitrogen , mass no = no of proton + neutron = 14
atomic no = no of proton = 7
no of neutron = 14 - 7 = 7
Helium , mass no = no of proton + neutron = 4
atomic no = no of proton = 2
no of neutron = 4 - 2= 2
fluorine , mass no = no of proton + neutron = 19
atomic no = no of proton = 9
no of neutron = 19-9 = 10
C - P waves move quickly and S waves move slowly through solids.
The sun gives energy to producers or plants. Then, the herbivores that eat the plants. After that the first level consumers eat the herbivores. Then the second level consumers eat the first level consumers, then so on. This might seem like there is a lot of energy from level to level. But, only 10% of each level goes to the next level. The other 90% is used for energy.
Thanks for the opportunity to answer your question and I hope that this helps! :)
