Step 1
(i) 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. The height of the person is 165 cm, and by examining the diagram, we can estimate the bear's height to be approximately twice that amount, as it appears to be about double the height of the person. Therefore, the estimated height of the bear is:
A reasonable range for the bear's height could be from 297 cm to 363 cm based on the proportions in the diagram.
Step 2
(ii) Which process occurs in animal cells that results in growth?
Answer
The process that occurs in animal cells which results in growth is called mitosis. Mitosis is a type of cell division where one parent cell divides to produce two identical daughter cells, leading to an increase in cell number and thus contributing to the overall growth of the organism.
