The presence of external ears or pinnae is a characteristic feature of:
The NCERT text for Mammalia states: 'External ears or pinnae are present.'
Which of the following mammal examples belongs to the genus Panthera?
The examples provided include 'Panthera tigris (Tiger), Panthera leo (Lion)'. Thus, Panthera leo is an example from genus Panthera.
Mammals regulate their body temperature, meaning they are:
The NCERT text for Mammalia states: 'They are homoiothermous.' Homoiothermous means warm-blooded, capable of maintaining a constant body temperature irrespective of the external environment, contrasting with poikilothermous (cold-blooded).
The vertebral column in mammals, such as humans, is primarily composed of how many serially arranged units?
The 'LOCOMOTION_AND_MOVEMENT' chapter states: 'Our vertebral column (Figure 17.7) is formed by 26 serially arranged units called vertebrae and is dorsally placed.'
The vertebral column protects the spinal cord, supports the head, and serves as the point of attachment for:
The 'LOCOMOTION_AND_MOVEMENT' chapter states: 'The vertebral column protects the spinal cord, supports the head and serves as the point of attachment for the ribs and musculature of the back.'
In which subphylum are protochordates exclusively marine?
The NCERT text states: 'Subphyla Urochordata and Cephalochordata are often referred to as protochordates and are exclusively marine.'
Which of the following statements correctly describes Newton's First Law of Motion?
According to the NCERT text, 'To summarise, if the net external force is zero, a body at rest continues to remain at rest and a body in motion continues to move with a uniform velocity.' This accurately describes Newton's First Law, emphasizing uniform velocity, not constant acceleration, in the absence of a net external force.
The property of a body to resist a change in its state of rest or uniform motion is called:
The NCERT text states: 'This property of the body is called inertia. Inertia means ‘resistance to change’.' Therefore, inertia is the correct term for this property.
If the net external force acting on a body is zero, its acceleration will be:
The text states that Newton's second law is consistent with the First Law ($F = 0$ implies $a = 0$). This means if the net external force is zero, the acceleration (rate of change of velocity) is also zero. This aligns with the concept of inertia, where a body maintains its state of motion (either rest or uniform velocity).
Galileo's experiments involving a ball rolling on inclined planes led to the conclusion that:
The NCERT text mentions: 'Galileo thus, arrived at a new insight on motion that had eluded Aristotle and those who followed him. The state of rest and the state of uniform linear motion (motion with constant velocity) are equivalent. In both cases, there is no net force acting on the body.'
