<span>Vertebrates
are known to be animals with backbones.
The following are the evolutionary changes of vertebrates:</span>
*Jaws
- Fishes before sucked and rubbed on their preys but now, they already have
jaws that enable them to more efficacious in getting their preys.
*Lungs
and limbs - Animals on the sea need to adapt when they look for their preys on
land, in turn, they had evolved to acquiring lungs for breathing and limbs for moving.
*Endothermy
- ‘Endo’ meaning internal and ‘therm’ meaning temperature. This gave animals’
bodies heat supply from burning the food they eat.

Answer:
Water is denser as a liquid than as a solid.
Explanation:
The property of water that makes icebergs float on is due to the fact that <u>water as a liquid is denser than as a solid</u>.
According to the rules of floatation,<em> a less dense substance will always float on a denser liquid because a body will always displace its own weight when placed in a liquid</em>. At room temperature, water as a liquid has a density of 1 g/cm3 but if the same water forms ice, the density would be 0.92 g/cm3. Hence, when ice is placed on water, it will float on it.
