Вопрос:

Petr planted ten pumpkin seeds in two beds. He watered the first bed every day and the second bed only once after planting because he thought the soil there was moist enough. After two weeks, the boy saw that 9 seeds sprouted in the first bed and 2 in the second. 1. Fill in the table using the previous text. 2. What conclusion can be drawn from the experiment's results? - Watering frequency does not affect seed germination - To plant pumpkin seeds, you need to wait for warm weather - Pumpkin seed germination is higher if the plantings are watered every day

Analysis of the experiment:

The experiment describes two conditions for watering pumpkin seeds: daily watering and occasional watering. The results show a significant difference in germination rates, with 9 seeds sprouting under daily watering and only 2 under occasional watering.

Table completion:

Based on the text, we can fill in the table as follows:

Conditions of germinationNumber of seeds planted (pcs.)Number of sprouted seeds (pcs.)Germination (%)
Watering every day10990%
Occasional watering10220%

Conclusion from the experiment:

The experiment clearly demonstrates that the frequency of watering significantly impacts the germination of pumpkin seeds. Daily watering led to a much higher germination rate (90%) compared to occasional watering (20%).

Answer:

  • 1. The table is filled as shown above.
  • 2. The correct conclusion is: Pumpkin seed germination is higher if the plantings are watered every day.
