In DNA replication, the new strand of dna that is synthesized in one continuous piece is called the leading strand
The correct answer to this question is "Including a control group that did not receive the supplement." This is the change in this study that would do the most to increase Reynaldo's confidence that sound scientific practices were followed. It would help them distinguish the effect of the drug and other factors which might have influenced the study. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
Answer:
The categories of patterns of evolution are: <em>genetics/molecular biology, direct observation of evolutionary change, the fossil record, homology/anatomy, and biogeography</em>
Explanation:
- <u>Anatomy.</u> Also known as Homology, is the study of homologous structures of species with similar physical features, as proof of direct descent and ancestry.
- <u>Molecular biology and Genetics</u>. DNA and the genetic code reflects the shared ancestry of life, indicative of how species are related.
- <u>Fossil Records.</u> Fossils register the existence of pre-existing species which are related to present-day species.
- <u>Biogeography</u>. The geographic distribution of organisms on Earth, as well as their distinct features is an indicator of evolution and geological change.
- <u>Direct observation. </u>Organisms with short lifespan can be observed as evolutionary cases.
Answer:
The correct answer will be option-C.
Explanation:
The myelin sheath is the protein-fat rich layer around the neurons which helps in the protection and insulation of the neurons to transmit signals at a faster rate.
The myelin sheath in both CNS and PNS are formed by the wrapping of the cells around the neurons. These cells which wrap around the neurons differ in CNS and PNS as the myelin sheath in CNS is formed by the oligodendrocytes whereas in PNS by the Schwann cells.
Thus, option- C is the correct answer.
