Answer 1

Question 7: Option B is the correct answer.

New World monkeys: These are the only monkeys that have a prehensile tail when compared with the non-grasping shorter, tails of the anthropoids of the Old World monkeys with Cheek pouches & ischial callosities ( cercopithecines- anatomical features), premolars and nose.

Question 8: Option A is the correct answer.

Basal metabolic rate (BMR) can be stated as the rate of energy expenditure per unit time by endothermic animals that are at resting conditions.  A higher metabolic rate is present in more active animals than in less active animals.

Question 9: Option E is the correct answer.

Orangutans are the only anthropoid primates with a solitary social system with social bonds occurring which live alone. Orangutans are also more likely than females to travel on the ground. There is food scarcity during the dry season, which is why orangutans are semi-solitary creatures.

Question 10: Option A is the correct answer.

In the animal kingdom, grooming is one of the widespread activity but in primates, social grooming, or the grooming of others (allogrooming), plays a major role in social bonding, which, in turn, has a particular impact on an individual's lifetime reproductive fitness.
