Match List I with List II:
Choose the correct answer from the options given below:
To remember these components:
• Centromere plays a key role in cell division,
• Cilium aids in cell movement,
• Cristae are structures within mitochondria,
• The cell membrane is composed of a phospholipid bilayer.
The correct matches are:
(A) Centromere is involved in Cell division (II).
(B) Cilium is involved in Cell movement (III).
(C) Cristae are found in Mitochondrion (I).
B Cell membrane consists of Phospholipid Bilayer (IV).
Thus, the correct matches are: \(A - II, \quad B - III, \quad C - I, \quad D - IV\)
Three crosses were carried out in pea plants with respect to flower colour violet/white (V/v) and flower position axial/terminal (A/a). Study in the table the crosses ‘a’, ‘b’ and ‘c’ where parental phenotypes and their $F_1$ progeny phenotypes are given.
Find the genotypes of each of the parental pairs of crosses ‘a’, ‘b’ and ‘c’.
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
