C Correct answer
Explanation

Ovulation is the process of releasing the matured egg or ovum.
Puberty is the process of physical changes whereby the child's body matures into an adult body capable of sexual reproduction.
The cessation of the woman's menstrual cycle and hence the end of reproductive ability is called as menopause. Menopause occurs due to the natural cessation of the estradiol and progesterone production by the ovaries over a period of years. This is the part of the normal aging process.
The process of becoming mature is maturation.

Explanation
  • The first menstrual cycle that occurs during puberty at the age of $11-14$ years is known as menarche.
  • The last menstrual cycle or cessation of the menstrual cycle at the age of $45-50$ years is known as menopause. 
  • Menarche marks the beginning of reproductive life and menopause marks the end of the reproductive cycle.
Implantation is the attachment of blastocyst to the endometrium of the uterus. It occurs after around 7 days after fertilization.
  • Parturition is the expulsion of the baby from the mother's womb after completion of the gestation period (9 months).

Hence, the correct option is C.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The gamete formation in females is a cyclic activity that takes about 28/29 days and involves changes in the structure and function of the entire reproductive system. It is called menstrual cycle.

It occurs only in primates( monkeys, apes and human beings). The latter do not show a cyclic change in sex urge and permit copulation at any time in the menstrual cycle. Human female may accept a male at any time, though there is variation in her level of desire.
So, the correct answer is 'Menstrual cycle is present in all primates'

Multiple choice biology the age of adolescence menstruation in females changes at puberty what happens if an egg is not fertilized?

Which is correctly matched in a normal menstrual cycle?

  1. Endometrium regenerates - 5 to 10 days
  2. Release of egg- 5$^{th}$ day

  3. Endometrium secretes nutrients for implantation- 11 to 18 days

  4. Rise in progesterone level- 1 to 15 days
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Just after the menstrual phase, the proliferative phase starts that shows an increase in the level of the FSH or follicular stimulating hormone. This leads to the regeneration of the endometrium lining. The regeneration takes around 5 to 10 days. On the 14$^{th}$ day, the ovulation takes place.

So, the correct option is 'Endometrium regenerates - 5 to 10 days'.
