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:
Góndolas.
Explicación:
El principal órgano reproductor que se utiliza en el proceso de reproducción y nacimiento del bebé son las gónadas. Las gónadas están formadas por ovarios y testículos que son responsables de la producción de óvulos en las hembras y espermatozoides en los machos. Cuando el óvulo de la hembra y el esperma del macho se fusionan, se forma un cigoto que se convierte en un nuevo bebé. Todos estos procesos ocurren dentro del feto de la hembra.
