I) Cyclical changes that occur during reproduction in primates is called the menstrual cycle.
II) Bamboo species flower only once in their lifetime, generally after 50-100 years, produce large numbers of fruits and die.
III) Many mammals, especially those living in natural, wild conditions exhibit oestrus cycle only during favourable seasons in their reproductive phase and are called continuous breeders.
IV) During the reproductive phase, there are concomitant changes in the body like slowing of metabolism.

• A. I and II are correct
• B. II and IV are correct
• C. I, III and IV are correct
• D. III and IV are correct

Answer 1

The correct option is A I and II are correct

The set of cyclical changes that occur in primate females after they are sexually mature is called the menstrual cycle. These changes are induced by reproductive hormones.

Bamboo plant flowers only once after 50-100 years in their lifetime.

Organisms that exhibit cyclical changes in the reproductive phase only during favourable seasons are seasonal breeders. Continuous breeders can reproduce throughout the year.

Concomitant changes like slowing of metabolism occur during the senescent phase.
