no because Separation of oxygenated and deoxygenated blood in the heart of three types of animals. The three-chambered frog heart mixes oxygenated and deoxygenated blood in the ventricle. Therefore, the body never receives fully oxygen-rich blood.

Answer:
D. Prokaryotes only have one origin of replication to initiate replication.
Explanation:
The DNA of prokaryotes is smaller than that of eukaryotes. So, prokaryotes have only one origin of replication. Origin of replication is the region of DNA where the process of DNA replication starts. The helicases recognize and bind to the origin of replication to start the melting of DNA double helix for replication.
DNA replication starts at the single origin of replication and stops at termination in prokaryotes.
Hello!
The sentence that best describes what Colton discovers is D) The mass of the melted ice cube remained the same at 4 grams.
<h2>Why?</h2>
The melting of the ice cube is a physical process. That means that it is a process in which the identity of the substance (water) doesn't change, but only how their molecules are arranged.
In melting, a substance in the solid state changes to the liquid state. Its molecules go from having a definite volume and shape to having the same shape as the container that holds it, but there are no changes in the mass of the substance.
If the container is closed, Colton should record the same mass as the initial one, as mass doesn't change in physical processes.
Have a nice day!
