Answer:
conservative replication model
Explanation:
In their experiment, Meselson and Stahl found that the DNA duplexes present after the first round of replication had intermediate density. This occurred since the semiconservative process of DNA replication of one DNA molecule (having both strands with 15N) forms two DNA duplexes each with one parental strand (15N) and one newly formed strand (14N).
If they had found two duplexes of two different density, this would have supported the conservative replication model. In this case, the DNA replication of the parent DNA molecule would have formed two DNA duplexes. One DNA molecule would have both the parental DNA strands with 15N while the other DNA duplex would have both newly formed strands with 14N.
<span>d. Adult stem cells are multipotent and can differentiate into types of cells
Stem cells are specialized cells that do not have a particular function nor structure on its prior form. These cells can be associated to be replacement cells or new cells depending on its type.
The adult stem cells are not multipotent and can only transform into some cell types..</span>
