Q4. Assertion: all locomotions are movements, but all movements are not locomotions. Reason: in NCERT’s animal-level examples, locomotion changes the place or location of the whole animal. Are both true, and does the reason explain the assertion?
Both are true, and the reason explains the assertion: locomotion is the particular kind of movement that changes place, so every locomotion is a movement, while movements such as chewing or blinking are not locomotion (NCERT page 217).
Q5. Name two cells in our body that show amoeboid movement.
Macrophages and leucocytes (NCERT page 218).
Q6. Which three systems must work together for human locomotion?
The muscular, skeletal and neural systems (NCERT page 218).
