Some important events that take place during fertilisation are given below. Arrange the events in a proper sequence and select the correct option. (i). Cortical reaction (ii). Sperm entry (iii). Karyogamy (iv). Acrosomal reaction

Arrange the following stages of fertilisation and early development into a proper sequence. I. Sperm entry II. Acrosomal reaction III. Karyogamy IV. Capacitation V. Cortical reaction

Write short notes on following events of the process of fertilisation: (i) Penetration of sperm into ovum. (ii) Cortical reaction of the ovum.

Which event ensures that only one sperm can fertilize an ovum ?

The following is the illustration of the sequence of ovarian events (a - i) in human female. ltimg src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/SB_BIO_XII_SET_I_2012_E01_032_Q01.png" width="80%"gt (i) Identify the figure that illustrates ovulation and mention the stage of oogenesis it represents. (ii) Name the ovarian hormone and the pituitary hormone that have caused the above mentioned event. (iii) Explain the changes that occur in the uterus simultaneously in anticipation. (iv) Write the difference between 'c' and 'h' (v) Draw a labelled sketch of the structure of a human ovum prior to fertilization.
