Choose the incorrect combination among the following:
Analyzing the combinations for accuracy.
Hensen's node (I): Correctly matched. It plays a crucial role in the gastrulation process by inducing the involution of chorda mesodermal cells.
Epimere (II): Incorrectly matched. Epimere forms the dorsal somatic mesoderm, primarily contributing to the development of dermis, skeletal muscles, and vertebral column, not directly related to the urinogenital organs.
Cowper’s glands (III): Incorrectly matched. Cowper's glands are not located beneath the urinary bladder; they are near the penile urethra and their secretions lubricate the urethra for sperm passage, not specifically for nutrition.
Mons pubis (IV): Correctly matched. It is indeed a cushion of fatty tissue present above the labia majora.
Match the following:
List–I | List–II |
---|---|
A. Ball and socket joint | I. Inter carpal joint |
B. Hinge joint | II. Between humerus and Pectoral girdle |
C. Pivot joint | III. Between carpals and metacarpals |
D. Gliding joint | IV. Between atlas and axis |
V. Knee joint |
The percentage error in the measurement of mass and velocity are 3% and 4% respectively. The percentage error in the measurement of kinetic energy is:
If \( L, M, N \) are the midpoints of the sides PQ, QR, and RP of triangle \( \Delta PQR \), then \( \overline{QM} + \overline{LN} + \overline{ML} + \overline{RN} - \overline{MN} - \overline{QL} = \):
