Select one:

True

False

Question 78

During ovulation, a secondary oocyte is released and will only complete meiosis II if fertilization occurs.

Select one:

True

False

Answer 1

71. Both oogenesis and spermiogenesis:

Creates haploid cells. Gamates are haploid cell and These cells develop into sperm or ova

72. Both A and B

73. oocyte will travel from ovary --> uterine (fallopian) tube --> uterus. The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus

74.During the secretory or luteal phase:

The corpus luteum is formed from an ovarian follicle.

75.What hormone is made by the placenta?

The correct answer is hCG.hCg is human chorionic gonadotropin and is the first hormone to be released from the developing placenta and is the hormone that is measured in a pregnancy test.

76.Fructose is present in semen to help provide energy to sperm -

It is true. Seminal fluid contains up to 11 mmol/L (200 mg/dl) of free fructose and is the major energy source for the sperm cells.

77. 4-5 days after fertilization, the blastocyst freely floats in the uterus prior to implantation -

It is true. After 4-5 days,the morula changes into blastocyst prior to implantation

78. During ovulation, a secondary oocyte is released and will only complete meiosis II if fertilization occurs -

It is true. The secondary oocyte which is released from the ovary performs meiosis ll , only if fertilization by sperm occurs.
