How long did it take for vertebrates to transition from water to land?

• Thousands of years

• Hundreds of thousands of years

• Millions of years

• A billion years

Why is the one bone/two bone/many bones/digits limb pattern important for origin of the tetrapods?

• It completes the fossil record.

• It shows how fish developed legs once on land to become tetrapods.

• It can show how all tetrapods still have basic fin bones.

• It can show a pattern of relatedness over time.

Where are the transition metals?

Answer explanation

Transition metals are a group of elements located in the middle of the periodic table. They are located in the d-block of the periodic table, which includes Groups 3-12. These elements are characterized by having partially filled d-orbitals in their outermost electron shell. Transition metals are known for their high melting and boiling points, as well as their ability to form complex ions and compounds.

Change of state from a solid directly to a gas is called

• deposition

• melting

• evaporation

• sublimation
