Table comparing amino acid differences in cytochrome C between humans and different animals.

Problem Analysis:

The task involves analyzing a table that compares the number of amino acid differences in the cytochrome C protein between various animals and humans. The goal is likely to infer evolutionary relationships or similarities based on these differences. Cytochrome C is a highly conserved protein, meaning that species more closely related to humans will have fewer amino acid differences in their cytochrome C compared to humans.

Table Breakdown:

The table lists animals along with the number of amino acid differences in their cytochrome C proteins compared to human cytochrome C. Here is the data:

| Animal | Number of Amino Acid Differences Compared to Human Cytochrome C |
|----------|---------------------------------------------------------------|
| Horse | 5 |
| Chicken | 7 |
| Tuna | 11 |
| Frog | 9 |
| Shark | 14 |
| Turtle | 8 |
| Monkey | 1 |
| Rabbit | 4 |

Solution Approach:

1. Understanding the Data:
- The number of amino acid differences indicates how similar the cytochrome C protein is between humans and each listed animal.
- Fewer differences suggest a closer evolutionary relationship to humans, while more differences suggest a more distant relationship.

2. Sorting by Similarity:
- To identify which animals are most closely related to humans, we can sort the animals based on the number of amino acid differences (from smallest to largest).

3. Interpreting the Results:
- Animals with fewer differences are more closely related to humans.
- Animals with more differences are more distantly related to humans.

Step-by-Step Solution:

#### Step 1: Sort the Animals by the Number of Differences
We arrange the animals in ascending order of the number of amino acid differences:

- Monkey: 1 difference
- Horse: 5 differences
- Rabbit: 4 differences
- Chicken: 7 differences
- Turtle: 8 differences
- Frog: 9 differences
- Shark: 14 differences
- Tuna: 11 differences

#### Step 2: Interpret the Results
- Monkey has the fewest differences (1), indicating it is the most closely related to humans.
- Shark has the most differences (14), indicating it is the most distantly related to humans among the listed animals.

Final Answer:

The animals can be ranked from most closely related to humans to most distantly related as follows:

1. Monkey (1 difference)
2. Horse (5 differences)
3. Rabbit (4 differences)
4. Chicken (7 differences)
5. Turtle (8 differences)
6. Frog (9 differences)
7. Tuna (11 differences)
8. Shark (14 differences)

Thus, the most closely related animal to humans is the Monkey, and the most distantly related animal is the Shark.
