Question

1. how would you demonstrate the effect of nutrient deficiency on plant growth? (10 points) by observing faster growth and greener leaves. by observing increased flower production. by observing the plant growing taller and stronger. by observing stunted growth and yellowing leaves. 5. what is the primary function of the digestive system in animals? (10 points) storing excess water filtering waste from the blood breaking down food to absorb nutrients producing energy directly from sunlight 6. how would you demonstrate the process of nutrition in amoebas? (10 points) by showing how amoebas use tentacles to capture prey. by showing how amoebas photosynthesize to produce food. by showing how amoebas absorb nutrients through their cell walls

Explanation:

• For question 4, nutrient - deficiency causes stunted growth and yellowing leaves in plants, not positive growth signs.
• For question 5, the main job of the animal digestive system is to break down food for nutrient absorption. Storing water is not its main function, filtering waste from blood is the job of kidneys, and animals don't produce energy from sunlight.
• For question 6, amoebas absorb nutrients through their cell walls. They don't have tentacles like some other organisms and they don't photosynthesize.

Answer:

1. By observing stunted growth and yellowing leaves.
2. Breaking down food to absorb nutrients
3. By showing how amoebas absorb nutrients through their cell walls.
