True or false

1.are rain fog and snow examples of precipitation?

2. and is the earth made of 70% water?

3. do water particles fall to the earths surface after their temperature increases?

4. water in a puddle enters the atmosphere when it evaporates?

5. clouds are made up of tiny droplets or ice crystals?

6. water vapor condenses into a liquid when it gains energy

7. the suns energy doesn't not play an important role in the water cycle

8. precipitation falls to the earths surface because of the force of electricity

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

hello

answer: collecting information/data

reason: the student is going around and asking people questions to collect data

i hope this

the answer is c because it is most logical.
