Answer:
A: Unlike DNA, XNA replicates conservatively
Explanation:
<em>The replication of the DNA is </em><em>semi conservative.</em><em> This means that newly replicated double helix DNAs usually consist of one parental strands and one newly synthesized strands. The parental DNA unwinds and each strand serves as template for the synthesis of complementary strands.</em>
In the case of XNA, the two strands of parental XNA were found intact, meaning that the newly produced XNA consist of two newly synthesized strands. This thus means that the replication process is conservative.
Hence, unlike DNA replication that is semi conservative, XNA replication is conservative.
The answer should be B, prokaryotic cells use binary fission as a means of "reproduction"
Explanation:
nitrogen is converted from atmospheric nitrogen +N2) into usable forms ,such as NO2,- in a process known as fixation.
Answer: Biotic means a living factor in the environment. The opposite would be abiotic, which is a non-living factor like light, pH, wind, etc.
Explanation:
Answer:
Explanation:
Inbreeding results which can increase the chances of offspring being affected by deleterious or recessive traits. This usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce.
