Answer:
10: Number of protons always equal number of electron, but that's the case with a neutral atom. ... This implies that it has same number of protons and electrons in it. It means it has same amount of positive and negative charge, which cancel each other, and the atom as a whole becomes electrically neutral.
19: The three stable isotopes of Argon, Argon-36, Argon-38, and Argon-40, would all have 18 protons and 18 electrons if they are all neutral. The three isotopes will have different numbers of neutrons compared to each other (18, 20, and 22 neutrons respectively).
20: This isotope of fluorine has 9 protons, 9 electrons and 10 neutrons.

Cell membrane is a semipermable, which means that certain molecules will be able to pass through the membrane. It is contains phospholipids. But for smaller molecules such as CO2 and Water, it can pass through the membrane through simple diffusion. Cell membrane controls the movement of the materials into and out of the cell.

Answer:
Which data help hydrologists predict floods?
Impermeable land area
Snowpack
Explanation:
Impermeable land area
, Snowpack
The above factors are very essential to an hydrologist to predict floods though other factors such as topography, drainage among others are also inclusive to make the prediction rightly.
