Answer:
DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are. Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Explanation:
Answer:
Over time the beetle population will adapt as a result of natural selection because the beetles "desired" by the birds will be eaten and their population will dimish as a result. The beetles that are not eaten by the birds will have a chance to allow their population to grow because a. they aren't being eaten and b. they have more space as the other colored beetle's population is shrinking. Causing the eaten species to become less prominant and the not eaten beetle's population to grow and take over in place of the other beetles.
I think it is A because birds do help spread around the seeds hope i helped
Explanation:
1. Using bits and pieces of other sources and passing it off as one’s own work
Patchwork plagiarism
In patchwork plagiarism, an author uses bits from other people's works and pass it off as their own.
2. Passing off another person’s work as one’s own
Plagiarism
The act of passing off another person's work as one's own is called plagiarism. It is a very serious offence
3. Passing off the entire work of another person as one’s own
Global plagiarism
Global plagiarism is the complete passing off of another person's own.
4. When most of the work is one’s own, but uncited sources are used
Incremental plagiarism
Here an author fails to cite the sources where he/she obtains information from.

Answer:
DNA ligase
Explanation:
DNA replication is an enzyme mediated, 3-step process during which the DNA molecule produces a copy of itself. The 3 steps involved are as follows;
- initiation
- elongation
- termination
<em>Initiation </em>involves the unwinding of the double helix structure of the DNA using DNA helicase enzyme
<em>Elongation</em> involves binding of RNA primer to the DNA strands and addition of bases to the primer<em> </em>to elongate the new chains. Bases are added to the leading strand continuously while the lagging strand is replicated in short segments (okazaki segments).
<em>Termination</em> involves the unbinding of RNA primer and substitution of its bases by DNA bases. The Okazaki fragments are then joined together using the DNA ligase enzyme.
<em>The short, numerous segments of DNA observed in the mixture is the Okazaki fragments of the lagging strand. This is due to the absence of the enzyme involved in the joining of these fragments.</em>
Hence, the answer is DNA ligase.
