A cube of side 125 cm is painted red on all the faces and then cut into smaller cubes of side 25 cm each. Find the number of smaller cubes having at least two faces painted.

Which of the following statements are correct about the structure of a sperm?

• [A.] It is composed of head, thorax, neck and tail.
• [B.] The neck region contains a lot of mitochondria.
• [C.] The mitochondria produce energy for the movement of the tail.
• [D.] The tail facilitates sperm motility essential for fertilization.

Select the correct sequence of events in human spermatogenesis:

• [(A)] Spermatid
• [(B)] Spermatogonia
• [(C)] Spermatozoa
• [(D)] Secondary Spermatocytes
• [(E)] Primary Spermatocytes

Spermatogenesis starts at the age of puberty due to a significant increase in secretion of Gonadotropin Releasing Hormone (GnRH). Increased levels of GnRH stimulate the secretion of two gonadotropins which are:

A pregnant female was admitted to the labour room. Mild uterine contractions started, but further strong uterine contractions were not taking place. Which of these could a doctor inject to induce delivery?

A primary spermatocyte after first meiotic division leads to the formation of secondary spermatocytes. These are:

Which among the following hormones is not produced by placenta?

Arrange the following events in correct sequence:

• [A.] Formation of zygote
• [B.] Formation of blastocyst
• [C.] Implantation
• [D.] Formation of morula

Select the correct statement/s from the following:

• [A.] Spermatogonia always undergo meiotic cell division.
• [B.] Primary spermatocytes divide by mitotic cell division.
• [C.] Secondary spermatocytes have 23 chromosomes and undergo second meiotic division.
• [D.] Spermatozoa are transformed into spermatids.

In the following statements, identify the stages of oogenesis in the order in which they occur:

• [(A)] During fertilisation, formation of egg and second polar body.
• [(B)] Meiosis II commences but stops at metaphase II.
• [(C)] Meiosis I commences but stops at prophase I.
• [(D)] Formation of primary oocyte from oogonia.
• [(E)] Meiosis I completes and results in formation of secondary oocyte and first polar body.

Which of the following hormones is not produced by the placenta?

Two cells \(\varepsilon_1\) and \(\varepsilon_2\) are connected in opposition to each other as shown in the figure. The cell \(\varepsilon_1\) is of emf \(9\ \text{V}\) and internal resistance \(3\ \Omega\). The cell \(\varepsilon_2\) is of emf \(7\ \text{V}\) and internal resistance \(7\ \Omega\). The potential difference between the points \(A\) and \(B\) is:

A battery of emf \(15\ \text{V}\) and internal resistance of \(4\ \Omega\) is connected to a resistor. If the current in the circuit is \(2\ \text{A}\), the resistance of the resistor and terminal voltage of the battery will be:

Choose the correct combination of three resistances \(1\ \Omega\), \(2\ \Omega\) and \(3\ \Omega\) to get equivalent resistance \(\dfrac{11}{5}\ \Omega\).

A wire has a resistance of \(2.5\ \Omega\) at \(28^\circ C\) and a resistance of \(2.9\ \Omega\) at \(100^\circ C\). The temperature coefficient of resistivity of the material of the wire is:

A slab of material of dielectric constant \(K\) has the same area \(A\) as the plates of a parallel plate capacitor, and has thickness \(\left(\frac{3}{4}d\right)\), where \(d\) is the separation of the plates. The capacitance when the slab is inserted between the plates is:

A parallel plate capacitor of capacitance \(5\ \mu F\) and plate separation \(6\ \text{cm}\) is connected to a \(1\ \text{V}\) battery and charged. A dielectric of dielectric constant \(4\) and thickness \(4\ \text{cm}\) is introduced between the plates of the capacitor. The additional charge that flows into the capacitor from the battery is:

A parallel plate capacitor having area \(A\) and separated by distance \(d\) is filled by a copper plate of thickness \(b\). The new capacity is:
