REPRODUCTION IN VERTEBRATES – LIFE SCIENCES QUESTIONS AND ANSWERS Reproduction is a fundamental aspect of life, essential for the continuity of species across the vast tapestry of the animal kingdom. Among the diverse array of organisms, vertebrates hold a special place, exhibiting fascinating mechanisms and strategies for reproducing. In this blog post, we delve into the intriguing world of vertebrate reproduction, exploring common questions and uncovering the marvels of life sciences.

Questions
Indicate whether each of the statements in COLUMN I applies to A ONLY, B ONLY, BOTH A and B or NONE of the items in COLUMN II. Write A only, B only, both A and B, or none next to the question number (1 to 5).
| COLUMN I | COLUMN II |
| 1. Oviparous | AÂ Eggs are produced BÂ Eggs are always incubated by the female |
| 2. Ovoviviparous | A Eggs incubated in nests B Eggs incubated in the female’s body |
| 3. Precocial | AÂ Small, helpless offspring born BÂ Intense parental care required |
| 4. Viviparous | AÂ Gestation period required BÂ Live offspring born |
| 5. Altricial | AÂ Intense parental care required BÂ Offspring can look after themselves |

Answers to activity 1
-  A only (B is wrong, because some animals, like insects, simply lay their eggs and do not incubate them. In some birds both the male and female incubate the eggs)
- B only (A is wrong, because the eggs are not released from the female’s body)
-  None (Precocial animals are born quite well-developed, they can live independently from their parents and find their own food, so parental care is not required)
- Both A and B
- A only (B is wrong, because altricial animals are born small and helpless. They cannot look after themselves or find their own food. Their parents must look after them, protect them and feed them.) (5 × 2) [10)
