Question 6
6. Use the scenario to answer the question.

A student is studying the effects of sunlight on tomato plants. She chooses 6 tomato plants, making sure that each of them receives the same amount of water and fertilizer each day. She gives one plant 0 hours of sunlight each day, with the other 5 plants receiving 1, 3, 5, 7, and 9 hours of sunlight. At the end of the experiment, she has people try a tomato from each plant and has them rank the fruits by their sweetness. She also records the total number of leaves produced on each tomato plant.

Which variable was controlled in the experiment?

Question 9
9. Which of the following best describes how plants and animals in the taiga biome might be impacted by a warm and dry summer, and how they could adapt to survive?(1 point)
Responses

Plants would thrive due to the increased warmth, while animals would migrate to cooler regions without any challenges.
Plants would thrive due to the increased warmth, while animals would migrate to cooler regions without any challenges.

Plants might struggle with drought stress, and animals could face food shortages, but both might adapt through water conservation and behavioral changes.

Question 10
10. Which statement best explains how differences in water transport between vascular and nonvascular plants affect their height?(1 point)
Responses

Nonvascular plants rely on gravity to move water, allowing them to grow taller than vascular plants.
Nonvascular plants rely on gravity to move water, allowing them to grow taller than vascular plants.

Nonvascular plants use specialized tissues to move water efficiently, enabling them to reach great heights.
Nonvascular plants use specialized tissues to move water efficiently, enabling them to reach great heights.

Vascular plants have specialized tissues like xylem and phloem that transport water and nutrients, allowing them to grow taller than nonvascular plants, which rely on diffusion and osmosis.
Vascular plants have specialized tissues like xylem and phloem that transport water and nutrients, allowing them to grow taller than nonvascular plants, which rely on diffusion and osmosis.

Both vascular and nonvascular plants use xylem for water transport, so their height is unaffected by differences in water transport methods.

Question 11
11. What is the primary purpose of roots in a plant, and how would a disease affecting the roots impact the plant's survival?(1 point)
Responses

Roots store excess sunlight for energy; a disease in the roots would stop photosynthesis.
Roots store excess sunlight for energy; a disease in the roots would stop photosynthesis.

Roots transport oxygen to the leaves; a disease in the roots would cause the leaves to dry out.
Roots transport oxygen to the leaves; a disease in the roots would cause the leaves to dry out.

Roots absorb water and nutrients from the soil; a disease harming the roots would limit the plant's ability to access these resources, leading to poor growth and survival.
