Answer 1

Carchardon carcharias

Genus: capitalize

species: lower case

2. False

In general, names will no be changed unless there is evidence that two named genera or species are in fact one.

4. False

This is why they use Latin.

Answer 2

You should check out wikipedia.com.

My guess to number 2 is false and same with 4...but that's just my guess. You can probably google this stuff..or again, use wikipedia. :)

Good luck!

Answer 3

Carchardon carcharias

Answer 4

1. Carchardon carcharias. Also should be italicized since it's Latin.

2. True and False. Names can be changed but usually due to changes in taxonomy (i.e. the species is reclassified based on better data), not because the new name is "better".

3. The names are based on a common, systematic, nomenclature. The name tells you it relationship to other species. Plus, many species have multiple common names depending on where you are. Example: Arabidopsis thaliana (a plant commonly used in genetic studies) is called the thale crest, doe eared crest, mouse eared crest and other names. Scientific names are absolute.

4. No
