Here is the step-by-step solution to the questions in the worksheet.
1. Model 1 is a family tree. Circle the original parents of the family.
*
Reasoning: In a family tree diagram, the "original parents" (also called the founding generation) are located at the very top. They are the ones who do not have any lines connecting to them from above, but have lines going down to their children.
*
Action: You should circle the two robot figures at the very top center of the page (the one with the square head and the one with the round head).
2. How would you describe the organisms in the second row of Model 1 that are connected to the parents by a line?
*
Reasoning: The line coming down from the original parents represents birth or descent. The group directly below the parents consists of their immediate offspring.
*
Answer: They are the
children (or offspring) of the original parents.
3. Identify the three members of the family that "married in" by placing a star next to their figures in Model 1.
*
Reasoning: In this diagram, a "star" symbol is used to mark individuals who joined the family from the outside (marriage) rather than being born into it. Looking at the chart, there are exactly three robots marked with a star symbol on their bodies.
*
Action: Place a star next to these three specific robots:
1. The robot in the
second row on the far left (it has a triangle nose and spiky hair).
2. The robot in the
second row in the middle-right area (it has a triangle nose and straight hair).
3. The robot in the
third row on the far left (it has a round head and a triangle nose).
4. How are the organisms in the third line related to the organisms in the first line?
*
Reasoning:
* Line 1 = Grandparents (Original Parents)
* Line 2 = Parents (Children of Line 1)
* Line 3 = Children of Line 2
* Therefore, the organisms in Line 3 are the grandchildren of the organisms in Line 1.
*
Correction: The handwritten answer in the image says "from marriage," which is incorrect for describing the biological relationship between the top and bottom generations. The correct biological term is needed here.
*
Answer: They are the
grandchildren.

Final Answer:
1.
Circle the two robots at the very top of the diagram.
2.
They are the children (or offspring).
3.
Place stars next to the three robots that already have a star symbol drawn on them (one in the 2nd row on the left, one in the 2nd row on the right, and one in the 3rd row on the left).
4.
They are the grandchildren.
