Question

For the following items, match the vertebrate groups below with the descriptions that follow. Each choice may be used once, more than once, or not at all. honeycombed bones, females with one ovary, no teeth

1) amphibians
2) non-avian reptiles
3) chondrichthyans
4) mammals
5) avian reptiles

Answer 1

Honeycombed bones and females with one ovary are characteristics of avian reptiles (birds). The description of no teeth is strongly associated with avian reptiles due to their beaks, though some chondrichthyans may also lack functional teeth.

Step-by-step explanation:

To match the vertebrate groups below with the descriptions that follow, we need to understand the characteristics of each group. Here are the matches:

• Honeycombed bones - This attribute is characteristic of 5) avian reptiles, which are birds. The honeycombed structure allows for a combination of strength and lightness, facilitating flight.
• Females with one ovary - Typically, this is seen in 5) avian reptiles as well. Most female birds have only one functional ovary, which reduces body weight to optimize for flight.
• No teeth - Both 3) chondrichthyans and 5) avian reptiles can have no teeth in the sense that modern birds have beaks without teeth, and some chondrichthyans, like filter-feeding sharks, lack functional teeth. However, since avian reptiles are known for their beak, this feature is most strongly associated with them.
