Step 1
Estimate the height of the bear.
Answer
To estimate the height of the bear, we can use the height of the person in the diagram as a reference. The person is 165 cm tall. Observing the diagram, it is reasonable to approximate that the bear is about twice the height of the person. Thus:
Height of bear = 165 cm × 2 = 330 cm.
Therefore, the estimated height of the bear is 330 cm.
Step 2
Which process occurs in animal cells that results in growth?
Answer
The process that occurs in animal cells to result in growth is called mitosis. Mitosis is the type of cell division that produces two identical daughter cells from a single parent cell, enabling growth and tissue repair in multicellular organisms.
