Question
This passage describes glucosinolates in Drummond's rockcress plants.
a Drummond's rockcress plant
Drummond's rockcress is a plant that many insects eat. Insect damage to a plant's leaves can reduce its chances of survival.
Some Drummond's rockcress plants have chemicals in their leaves called glucosinolates (gloo-koh-SIN-oh-lates). Because glucosinolates are poisonous to many insects, these chemicals can keep insects from eating the plants.
The table below describes a possible population of Drummond's rockcress plants at the start of a period of time and at the end of that period. The table shows the glucosinolates trait in the population at each point in time.
Complete the table. Write the exact answers as whole numbers or decimals.

To complete the table, we need to calculate the missing values for the percentages at the start and end points in time.
First, let's calculate the total number of plants at both the start and end points.
### Start
- Number with glucosinolates: 181
- Number without glucosinolates: 69
- Total number of plants = 181 + 69 = 250
**Calculating Percentages:**
- Percentage with glucosinolates = (Number with glucosinolates / Total number) × 100
\[
Percentage\ with\ glucosinolates = \left( \frac{181}{250} \right) \times 100 = 72.4\%
\]
- Percentage without glucosinolates = (Number without glucosinolates / Total number) × 100
\[
Percentage\ without\ glucosinolates = \left( \frac{69}{250} \right) \times 100 = 27.6\%
\]
### End
- Number with glucosinolates: 372
- Number without glucosinolates: 28
- Total number of plants = 372 + 28 = 400
**Calculating Percentages:**
- Percentage with glucosinolates = (Number with glucosinolates / Total number) × 100
\[
Percentage\ with\ glucosinolates = \left( \frac{372}{400} \right) \times 100 = 93\%
\]
- Percentage without glucosinolates = (Number without glucosinolates / Total number) × 100
\[
Percentage\ without\ glucosinolates = \left( \frac{28}{400} \right) \times 100 = 7\%
\]
### Completed Table
Now we can fill in the table with these calculated values:
| Point in time | Number with glucosinolates | Number without glucosinolates | Percentage with glucosinolates | Percentage without glucosinolates |
|---------------|-----------------------------|-------------------------------|-------------------------------|-----------------------------------|
| Start | 181 | 69 | 72.4% | 27.6% |
| End | 372 | 28 | 93% | 7% |
So the completed table would look like this:
| Point in time | Number with glucosinolates | Number without glucosinolates | Percentage with glucosinolates | Percentage without glucosinolates |
|---------------|-----------------------------|-------------------------------|-------------------------------|-----------------------------------|
| Start | 181 | 69 | 72.4 | 27.6 |
| End | 372 | 28 | 93 | 7 |
First, let's calculate the total number of plants at both the start and end points.
### Start
- Number with glucosinolates: 181
- Number without glucosinolates: 69
- Total number of plants = 181 + 69 = 250
**Calculating Percentages:**
- Percentage with glucosinolates = (Number with glucosinolates / Total number) × 100
\[
Percentage\ with\ glucosinolates = \left( \frac{181}{250} \right) \times 100 = 72.4\%
\]
- Percentage without glucosinolates = (Number without glucosinolates / Total number) × 100
\[
Percentage\ without\ glucosinolates = \left( \frac{69}{250} \right) \times 100 = 27.6\%
\]
### End
- Number with glucosinolates: 372
- Number without glucosinolates: 28
- Total number of plants = 372 + 28 = 400
**Calculating Percentages:**
- Percentage with glucosinolates = (Number with glucosinolates / Total number) × 100
\[
Percentage\ with\ glucosinolates = \left( \frac{372}{400} \right) \times 100 = 93\%
\]
- Percentage without glucosinolates = (Number without glucosinolates / Total number) × 100
\[
Percentage\ without\ glucosinolates = \left( \frac{28}{400} \right) \times 100 = 7\%
\]
### Completed Table
Now we can fill in the table with these calculated values:

| End | 372 | 28 | 93% | 7% |
So the completed table would look like this:
| Point in time | Number with glucosinolates | Number without glucosinolates | Percentage with glucosinolates | Percentage without glucosinolates |
|---------------|-----------------------------|-------------------------------|-------------------------------|-----------------------------------|
| Start | 181 | 69 | 72.4 | 27.6 |
