The physical properties of water is that it is clear, it has no taste. No odour. It freezes at 0 degrees Celsius and boils at 100 degrees Celsius. The different stages of water is liquid, solid and gas. It is liquid at normal state. Ice when solid and steam when it is a gas state.
It is essential for human life because majority of the human body is made out of water. The water in the body allows certain parts and organs to function properly.

I believe the correct term to fill in the blank would be ionic. A molecule of common table salt, or nacl, is the result of ionic bond forming between a sodium (na) atom and a chlorine (cl) atom. Ionic bonding is a result of complete transfer of electrons between atoms. It usually happens between a metal and a nonmetal.
1. Solar nebula 2. The sun 3. Planetesimals 4. Inner planets, 5. Outer planets.
I believe that’s it
Answer:
45, 34, 36
Explanation:
The atomic number of Selenium is 34 and the atomic number is 79 also the atom has gained two electron denoted by superscript -2
number of neutrons = mass number - atomic number = 79 - 34 = 45
number of proton = atomic number = 34
number of electron = 34 + 2 = 36. In an atom the number of proton is always equal to number of electron if the atom is neutral but this Se atom has gain two so the number of electron will exceed the number of proton by 2.
The unified cell theory<span> states that: all living things are composed of one or more </span>cells<span>; </span>the cell<span> is the basic unit of life; and new cellsarise from existing </span>cells<span>. Rudolf Virchow later made important contributions to this </span>theory<span>. ... The cell is the fundamental unit of structure and function in living things
hope this helped :)
