Answer:

The amount of time that the 2 species have been evolving apart.

Explanation:

A molecular clock is a figurative term that refers to a technique that uses the mutation rate of biomolecules in order to deduce the time when two different but related life forms started to diverge. In this case, we know that the new organism is related to clownfish, and we would like to know when the two species began to evolve apart.

How will you evaluate the information that you retrieve from the library, by giving specific examples in one of your subject spe
DedPeter [7]

Answer:

You might think the answers to the questions “what is a library?” and “what is the Internet?” are pretty obvious. But actually, it is easy to get them confused, and there are a number of research resources that are a bit of both:  library materials available over the Internet or Internet resources available in the library.

Understanding the differences between the library and the Internet and knowing where your research comes from is crucial in the process of research writing because research that is available from libraries (either in print of electronic form) is generally considered more reliable and credible than research available only over the Internet.  Most of the publications in libraries (particularly in academic libraries) have gone through some sort of review process.  They have been read and examined by editors, other writers, critics, experts in the field, and librarians.

In contrast, anyone with appropriate access to the Internet can put up a Web page about almost anything without anyone else being involved in the process:  no editors, other writers, critics, experts, or anyone else review the credibility or reliability of the evidence.

However, the line between what counts as library research and what counts as Internet research is becoming blurred.  Plenty of reliable and credible Internet-based research resources are available: online academic and popular journals, Web-based versions of online newspapers, the homepages of experts in a particular field, and so forth.

Let’s begin with the basics of understanding the differences between libraries and the Internet.

Libraries are buildings that house and catalog books, magazines, journals, microfilm, maps, government documents, and other resources.  It would be surprising if you attended a community college, college, or university that did not have a library, and it would be equally surprising if your school’s library wasn’t a prominent and important building on campus.

As you might expect, libraries at community colleges, colleges, and universities tend to specialize in scholarly materials, while public libraries tend to specialize in non-scholarly materials.  You are more likely to find People magazine or the latest best-selling novels in a public library and a journal like College English  and scholarly books in a college library.

Many universities have different libraries based on distinctions like who tends to use them (“graduate” or “undergraduate” libraries) or based on specific subject matter collected within that particular library (education, social work, law, or medicine).  Almost all college and university libraries also have collections of “special items,” which include items like rare books, maps, and government documents.

Almost all universities, colleges, and community colleges in the United States provide students and faculty with access to the Internet so they can use email and the World Wide Web, or even so they can publish Web pages.  Millions of people both in and out of school have access to the Internet through “Internet Service Providers,” which are companies both large and small that provide customers access to the ‘net for a monthly fee.
