A scientist fills a glass container with water and places an aquatic plant inside the container, then closes the lid and places the container in direct sunlight. The scientist observes small bubbles on the surfaces of the plant’s leaves on days 1 and 2, but no bubbles on day 3. The scientist concludes that the bubbles were caused by photosynthesis. Which substance should be added to the water in order for the bubbles to reappear?(1 point)
Responses
oxygen

Which process do plants and animals share in common?
Plants and animals share the process of cellular respiration.
The taiga biome has long, cold, dry winters and cool, wet summers. In three to four sentences, describe how the plants and animals would be impacted by a warm and dry summer and how they might survive. Support your answer with the abiotic factors in the biome
A warm and dry summer in the taiga biome would create several challenges for both plants and animals. The lack of moisture would hinder plant growth and could cause dehydration and death, while animals that rely on these plants for food could face a shortage of resources. Additionally, increased heat and dryness could lead to an increase in wildfires, further disrupting the ecosystem. To survive, species might adapt by reducing their activity levels or migrating to areas with more favorable conditions, and some plants might have adaptations to conserve water or store nutrients.
