Type of symmetry in which body parts are arranged in a circle around a central point is called radial symmetry.
<span>
This type of symmetry is characteristic for the sessile animals like Cnidaria and Echinodermata. Organisms with radial symmetry have no left or right sides, they have a top and a bottom surface, or a front and a back.</span>
The range of a set of data is the difference between the highest and lowest values in the set.
And to find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
Chemical change is a process where a current substance changes or is made into a new type of substance<span>. Unlike the physical change, which is reversible. Chemical change stays into a its new form. Take for instance these -physical change- examples, making ice cubes. The process involves solidification or freezing where the water becomes ice or solid but when it melts back to its original or typical form with respect to temperature, it’s still water. When the paper is cut into pieces it isn’t burned or exposed to a stimuli that can trigger immediate change in its composition. It’s still the same. On the contrary, baking a cake involves these different compositions or substances –flour, egg, yeast and etc. that is baked to a cake, a newly formed unified substance of all the included ingredients. </span>
