Correctly match the names of the plant taxonomists (Group I) with the titles of the books they authored (Group II):
Let's match the plant taxonomists with their books:
- (P) John Hutchinson: Hutchinson is known for his work "The Families of Flowering Plants," which is considered a comprehensive guide to plant taxonomy. Hence, P-4 is the correct match.
- (Q) Adolf Engler and Karl Prantl: This pair authored the classic "Die Natürlichen Pflanzenfamilien," a multi-volume work that describes the natural families of plants. Hence, Q-3 is the correct match.
- (R) Arthur Cronquist: Cronquist is famous for his book "Evolution and Classification of Flowering Plants," which presents a new classification of plants based on evolutionary relationships. Hence, R-2 is the correct match.
- (S) Alfred Barton Rendle: Rendle is known for his book "Classification of Flowering Plants," which is a significant contribution to plant classification. Hence, S-1 is the correct match.
Thus, the correct answer is (A).
Correctly match the enzymes used as selectable markers (Group I) and the chemicals used for their selection (Group II):
Correctly match the economically important specialized metabolites (Group I) with their broad chemical classes (Group II):
The \( F_{121} \) value of a known microorganism with \( Z \) value of \( 11^\circ C \) is 2.4 min for 99.9999% inactivation. For a 12D inactivation of the said microorganism at \( 143^\circ C \), the \( F \) value (in min) is .......... (rounded off to 3 decimal places)
Three villages P, Q, and R are located in such a way that the distance PQ = 13 km, QR = 14 km, and RP = 15 km, as shown in the figure. A straight road joins Q and R. It is proposed to connect P to this road QR by constructing another road. What is the minimum possible length (in km) of this connecting road?
Note: The figure shown is representative.
For the clock shown in the figure, if
O = O Q S Z P R T, and
X = X Z P W Y O Q,
then which one among the given options is most appropriate for P?
