Answer:
Relative humidity, RH
Explanation:
RH, is the ratio of the amount of water vapor present in the air to the maximum amount of water vapor needed for saturation at a certain pressure and temperature
I'll say that it is +1 since hydrogen is desperate to lose an electron to fulfill the octave rule (that the molecules want to gain 8 electrons and if they can't do it, they want to lose all their electron). Electron is - so if it lose a electron, it becomes +.
Hopefully this helps.
PS. I'm not certain of my answer but it is logical.
Answer:
Oxygen liberated during photosynthesis comes from the splitting or hydrolysis of water in the green plants. Cornelius van Niel experimentally proved for the first time that the oxygen liberated during photosynthesis comes from water and not from carbon dioxide.
Answer:
1) Nitrogenous bases
2) Nucleotides
3) Purines
4) Pyrimidines
Explanation:
1) Each one is made up of a pentose , a group, and one of four Nitrogenous bases
2) Adenine, guanine, cytosine and thymine are Nucleotides
3. Adenine and guanine, which have a nine-member double-ring, are called Purines
4. Cytosine and thymine, which have a six-member single-ring, are called Pyrimidines
