Answer:
Answer is option B, i.e. ecological succession.
Explanation:
Ecological succession can be understood as a slow process of change that takes place in the ecology or ecosystem over a given period of time. One species takes over the other species naturally and gradually with changing condition that falls favorable for the former. Here, in the above mentioned case, the Raspberry plants took over the habitat of Pine trees after they were knocked down by the winds. With the passage of time and favorable conditions for the pine seedling, they took over the plantation area again.
Obstacles:
1.Lack of good governing system
2.Lack of formation of climate change investigation team
3.Awareness is not generated according to need
4.Passive concerned authorities

A is the one that is fatty acid as far as I know.
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.
