The molecule of water is different from the molecules of oxygen and hydrogen in the following ways:
1. Combustion: Oxygen supports combustion, hydrogen burns in the air to form water. Water is not combustible. It rather inhibits combustion when poured over burning substances.
2. State of matter: Water is a liquid in room temperature whereas oxygen and hydrogen are gases. The polar nature of water contributes to hydrogen bonding between the hydrogen and oxygen atoms of water.
3. Density: Water is denser than both oxygen and hydrogen. Hydrogen bonding helps pack more molecules of water in less space.
4. Freezing point: Water freezes to ice at 0°C whereas oxygen freezes at -218°C and hydrogen freezes at -259°C.

Answer:
The answer is false. Reproductive cells are not somatic cells.
To determine the median of a data set, you need to put all of the values
you have in their numerical order. Count how many figures there are
overall, if there is an even number, then the median will be the middle
number. if there is an even number, then to find the median number you
need to determine the mean of the two numbers in the middle. To
determine the mean of a data set, you first need to add together all the
values within the set. Next, count up how many overall values there
are, and then divide the previous total by the number of values that
there are.

Atp is adenosine triphosphate! This means an adenosine molecule (a nitrogenous base) bonded to 3 phosphate molecules and a 5 carbon sugar. The significance is that it is the energy currency of cell and for the whole body on a macroscale! So you need atp to do everything...even reading this right now!!! hydrolyzing it releases energy from the phosphate bonds that is used by the cell to do its work! So simply break apart atp molecules to get energy to do work!!!
