Question
scientists studied three different organisms to compare their basic life functions: a venus flytrap plant (organism a), a single - celled amoeba (organism b), and a laboratory mouse (organism c). they conducted several experiments to measure different aspects of life functions.
experiment 1: energy acquisition the researchers measured how each organism obtained and processed energy over a 24 - hour period.
table 1: energy acquisition methods and rates
| organism | nutrition type | energy source | energy acquired (joules/day) | co2 production (ml/day) |
|---|---|---|---|---|
| b | heterotrophic | bacteria | 0.8 | 0.02 |
| c | heterotrophic | plant material | 890 | 445 |
experiment 2: cellular response to environmental changes the scientists exposed each organism to various environmental conditions and measured their regulatory responses.
table 2: response to environmental changes
| condition | response time (seconds) | ||
|---|---|---|---|
| temperature change (±5°c) | 180 | 2 | 5 |
| ph change (±0.5) | 300 | 1 | 8 |
| light intensity change | 15 | 25 | 3 |
experiment 3: growth and reproduction the researchers tracked growth rates and reproductive capabilities over 30 days.
table 3: growth and reproduction data
| organism | cell division time (hours) | number of offspring | growth rate (mm/day) |
|---|---|---|---|
| b | 24 | 64 | 0.001 |
| c | 12** | 8 | 1.2 |
through leaf budding *average time for body cells
15 based on table 3, which statement about reproduction is supported by the data?
faster cell division always results in more offspring.
smaller organisms produce more offspring.
growth rate correlates with reproductive capacity.
different organisms use different reproductive strategies.
Looking at the data in Table 3 for growth and reproduction, Organism A (Venus fly - trap plant) reproduces through leaf budding and has a certain cell - division time, number of offspring, and growth rate. Organism B (amoeba) and Organism C (laboratory mouse) also have their own distinct values for these parameters. This shows that different organisms have different ways of reproducing, which is a demonstration of different reproductive strategies. Option A is incorrect because faster cell division does not always result in more offspring as seen with Organism C having faster cell division than Organism B but fewer offspring. Option B is incorrect as Organism C (a mouse, which is not a small organism) has more offspring than Organism B (amoeba) in some cases. Option C is incorrect as there is no clear correlation between growth rate and reproductive capacity shown in the data.
