I believe it is the second option
Eukaryota and most likely produces milk to feed its young
B
Because insulin can trigger liver to convert glucose in blood to glycogen.
Plant pollen can provide information of what type of plants grew during that era and area. In turn, it can also determine how the Earth''s climate has changed over time. Identifying the species of the plants through the pollen will help because when scientists compare them to the plants today and the climates they thrive in, they will be able to tell what type of climate that certain plant existed in.
The answer is True.
Answer:
The correct statements are,:
B. Resistance to the anti-viral drug ganciclovir indicates that homologous recombination has occurred.
C. Homologous recombinants of the knockout alleles are desired since they will replace the wildtype allele
E. The embryonic stem cells carrying homologous recombinants of the knockout allele are placed back into a blastocyst and injected into a surrogate mother to produce mice carrying the knockout allele.
Explanation:
<u>wrong statements</u>
A. Illegitimate recombinants have the knockout allele randomly inserted and do not replace the wildtype alleles and may potentially insert into other genes and confound the analysis
D. Resistance to neomycin indicates insertion of the knockout allele but does not distinguish between homologous and non-homologous recombinants
A and D are wrong statement due to the fact that Cells that were transformed with a vector containing the neomycin gene and the herpes tk+ gene are grown in a solution that contains neomycin and Ganciclovir in order to distinguish the transformations that occured through homologous recombination. Any DNA insertion that occurred through random insersion( illegitimate recombinant) will die because the tests positive for both neomycin resistant gene and herpes tk+ gene whose gene product reacts with Ganciclovir to produce deadly toxins.
