<u>Transition fossils show</u><u> the presence of leglike structures, pointing to the possibility that the ancestors of </u><u>whale</u><u> and dolphins once lived on land.</u>
- The cetaceans, which include whales, dolphins, and porpoises, are descended from land-dwelling mammals.
- Traces of their terrestrial ancestry can still be seen in the bones of their fins, which resemble enormous, jointed hands, in their vertical spine movement, and in the fact that they must breathe air from the surface.
What is evidence that whales evolved from land mammals?
- There are several indications from a whale's anatomy and biology indicating they originated on land.
- They have paddle-shaped flippers that house hand bones with five "fingers," breathe air, and nurse their young with their own milk.
- Whales have tiny back limbs as embryos, but these vanish before birth.

Answer:
yes
Explanation: The atoms and molecules that make up a gas are constantly moving. Temperature is a measure of the speed with which they move (more accurately it is a measure of their kinetic energy). The higher the temperature, the faster they move. It is thus produced a greater intensity in the collisions against the walls: the pressure of the container containing the gas increases.In this way, if the graph shows the increase in temperature as well as the increase in speed, yes, it is correct.
A scientist is conducting an investigation that involves water, silver, carbon dioxide, and oxygen gas. They are each made of matter. Some are compounds and some are elements. They all contain atoms. [ -best describe all of the materials he is using in the investigation. ]
