Thorn Palms Water Storage Traits

The video tutorial explores how water storage traits in thorn palms can change over generations under different rainfall conditions. It uses simulations to predict the distribution of these traits, comparing medium and low rainfall environments. The tutorial highlights the adaptive nature of high water storage traits, using cacti as an example, and demonstrates how these traits can become more common in specific environmental conditions.

What is the main focus of the prediction activity in the video?

• Predicting the water storage traits in Thorn Palms.

• Predicting the height of Thorn Palms.

• Predicting the growth rate of Thorn Palms.

• Predicting the color change in Thorn Palms.

How do cacti manage to survive in dry conditions?

• By storing water in their leaves.

• By shedding leaves to conserve water.

• By growing taller.

• By storing water in their bodies.

Why is high water storage considered an adaptive trait?

• It makes plants more attractive.

• It helps plants survive in dry conditions.

• It increases the plant's height.

• It allows plants to grow faster.

What is the significance of the histogram in the prediction activity?

• It shows the age distribution of Thorn Palms.

• It shows the water storage trait distribution of Thorn Palms.

• It shows the height distribution of Thorn Palms.

• It shows the color distribution of Thorn Palms.

What was the initial prediction about Thorn Palms under medium rainfall?

• Medium water storage traits would become more common.

• Low water storage traits would become more common.

• No change in water storage traits.

• High water storage traits would become more common.

After several generations under medium rainfall, what was observed in Thorn Palms?

• Increase in low water storage traits.

• No significant change in traits.

• Increase in medium water storage traits.

• Increase in high water storage traits.

What was the main observation after 50 generations under medium rainfall?

• No change in water storage traits.

• Low water storage traits increased.

• Medium water storage traits increased.

• High water storage traits increased.

What was the result of Thorn Palms under low rainfall conditions?

• No change in water storage traits.

• Low water storage traits became dominant.

• Medium water storage traits became dominant.

• High water storage traits became dominant.

What happened to the low and medium water storage traits under low rainfall?

• They disappeared.

• They increased slightly.

• They remained unchanged.

• They became more common.

What conclusion can be drawn about the impact of low rainfall on Thorn Palms?

• It favors low water storage traits.

• It has no impact on water storage traits.

• It favors medium water storage traits.

• It favors high water storage traits.
