Answer:
B. In fishes, blood passes through the gills, returns to the heart, and then is pumped to the systemic tissues.
Explanation:
In fish, blood does not pass through the gills, returns to the heart and is then pumped into the systemic tissues.
Most fish breathe through gills. Water continually enters the fish's mouth, bathes the gills and exits through the openings on either side of the head. Most fish breathe through gills, also known as gills. Water continually enters the fish's mouth, bathes the gills and exits through the openings on either side of the head.
The heart of the fish has two cavities, an atrium and a ventricle - and through it only unoxygenated blood circulates. After passing through the heart, unoxygenated blood goes to an artery and into the gills where it receives oxygen gas. This now oxygenated blood is distributed to all organs of the animal's body.
The reason why I think these fossils are more common fossils than those of soft tissues or microorganisms one reason is that soft tissues decompose better than bone which gives more time for them to be buried.
The correct answer is cohesion and adhesion.
The cohesion of the water means that the H₂0 molecules are attracted by other H₂O molecules (molecules of the same kind are attracted). Adhesion is the attraction of molecules of different kinds. <span>Water moving up a straw is an example of the motion of water against gravity which depends on the attraction between water molecules and the walls of the straw (adhesion), and also on the attraction between water molecules (cohesion).</span>
