If, someday, an archaean cell is discovered whose SSU-rRNA sequence is more similar to that of humans than the sequence of mouse SSU-rRNA is to that of humans, the best explanation for this apparent discrepancy would be

Conifer resin ducts, which are found in the cortex and phloem, contain a mixture of diverse terpenoids, which are released immediately upon damage by herbivores such as;
a) monocyclic terpenes like- limonene and terpinolene
b) bicyclic monoterpenes- α-pinene and β-pinene
c) tricyclic sesquiterpenes- longifolene, caryophyllene, and δ-cadinene
d) tetracyclic terpenes- longifolene, tetra-terpinolene terpenoids are incorrect?

Genes a, b, and c are widely spaced in the bacterial genome. Transducing phage from an a+ b+ c+ bacterium were used to infect a culture of a- b- c- cells, and b+ transductants were selected. Which of the following best describes the predicted genotypes of these transductants?

Following statements are regarding to the spindle position checkpoint pathway in budding yeast.
A. During interphase and early mitosis, Cdc14 is sequestered and inactivated in the nucleolus. Inactive Tem1-GDP associates with the spindle pole body (SPB) nearest to the bud as soon as the mitotic spindle forms.
B. If chromosome segregation occurs properly, extension of the spindle microtubules inserts the daughter SPB into the bud, causing Tem1 to be activated by an unknown mechanism.
C. Tem1-GDP activates a protein kinase cascade, which then promotes the release of active Cdc14 from the nucleolus and exit from mitosis.
D. If the spindle apparatus fails to place the daughter SPB in the bud, Kin4 (cyan), an inhibitor of Tem1, is recruited from the parent cell cortex to the parent-cell-located SPB and maintains Tem1 in the GTP-bound form, and mitotic exit does not occur.
Which of the following are correct?
