which of the following statements is not true about an animal’s circadian rhythm?
a) it’s not influenced by genetics, only the time of day
b) it can be adjusted or overcome with time and effort
c) it’s influenced by genetics and the time of day

Explanation:

First Question (Monkey Species Relationship)

• Tarsiers are not monkeys (they are prosimians) and have different traits.
• Strepsirrhines (like lemurs) are prosimians, lack opposable thumbs in the typical monkey - like way, and have other distinct features.
• New World monkeys typically have prehensile tails, while Old World monkeys do not have prehensile tails and often have opposable thumbs, and are arboreal (tree - climbing), matching the new species' traits.

Second Question (Circadian Rhythm)

• Circadian rhythms are known to be influenced by both genetics (internal biological clocks have genetic components) and environmental factors like the time of day.
• Statement B is true as circadian rhythms can be adjusted (e.g., adjusting to a new time zone with effort over time).
• Statement C is true as circadian rhythms have genetic influences (e.g., mutations in clock genes affect rhythms) and are also influenced by the time of day (light - dark cycles). So the statement that says it's not influenced by genetics is false.

Answer:

C) Old World monkeys
