It suggests that life changes over time by showing different animals at different stages in their life, also giving more than one example on how they can change during early development and throughout their lives
Water is 22.4
Final for both us 27.1
Explanation:
I just finished this part of the lab
NH4+ and NH3 are an acid-conjugate base pair, since NH4+ is an acid, while NH3 is its conjugate base (since it is without the H+).
H2O and H3O+ can also be considered an acid-conjugate base pair, since H3O+ is an acid, while H2O would be its conjugate base. (But if only 1 answer is to be selected, it should be the NH4+ and NH3)
NH4+ and H3O+ are both acids, and both H2O and NH3 can be considered bases.
The characteristics of carbon compounds are they exist with different structures in which the atoms are arranged differently and it forms more compounds than other elements combined.
Explanation:
The carbon atom has atomic number 6 which represents the number of electrons. It is represented by C and it is a non- metal. It has 6 protons, 6 neutrons, and 6 electrons. They are smaller in size so that it can fit in to larger molecules.
It is the only element that can form different compounds because each carbon atoms can form four chemical bonds to other atoms.
The structure of carbon atom is represented with its atomic number 6. The first two electrons are present in inner shell and the remaining four are present in the second shell.
The carbon combines with oxygen, hydrogen, and nitrogen to form many molecules for cellular function. Carbon and hydrogen combine to form hydrocarbon chains and rings.
For example the structural formula for Methane (CH4)
