Question

1.If two organisms are in different families, they must be in different phyla. True or False
2.if two organisms are classified in the same genus, what must also be true?

Answer 1

1. Families are different from phyla. Phyla are a larger category than families. So it could totally be possible, but not always true. So this would be false
2. If they are in the same genus, they must be in the same Kingdom, Phylum, Class, family, and Order.

Here is the taxonomic classification:
Kingdom
Phylum
Class
Order
Family
Genus
Species

Hope this helps :D

Answer 2

Each kingdom is divided into phyla. Each phyla is divided into classes. Each class is divided into order. Each order is divided into families. Each family is divided into genuses, and each genus is divided into species. So examples of species are dogs, wolves, and tigers. Dogs and wolves are in the same genus, Canis. Dogs and wolves and foxes are all in the same family, the dog family, just like lions and tigers are in the Cat family. Several families are gathered into Orders, such as Order Carnivora. Several orders are in the same class, such as Class Mammalia. Many different classes are gathered into a Phylum. So Phylum Vertebrata contains Class Mammalia, Class Aves (birds), Class Amphibia, and so on.
