Answer:
lack of sunlight, overcrowded region for shelter of the plants, no nutrients and water supply, etc.
Explanation:
The plants needs favorable climatic conditions and nutrient to grow. Plants need air, sunlight, water, proper temperature, nutrients, etc. grow and make their food. They make their food with the help of sunlight and carbon dioxide by a process called as photosynthesis.
Now in the context, Amy is setting up an experiment where she will study the growth of plants in two models. One in the normal growing conditions and the other in a drought condition.
Drought is considered the most important abiotic factor that limits the growth and adversely affects the growth and the crop. The factor that is important for Amy to change the model into a drought conditions is the lack of water and carbon dioxide in the atmosphere. Also scarcity of sunlight and nutrients. The drought stress is considered as one of the crop performance limiting factors.
The answer is 232 plus 450

neutrons should be added with the protons
Answer:
Momentum of first train car will reduce
Explanation:
When the moving care collides with the stationary car, it will increase the momentum of the stationary car. However, its own momentum will reduce.
It is so because the speed of the first train car will reduce after collision due to loss of energy in the collision while the stationary car may gain some momentum due to rise in velocity from zero (velocity at stationary position).
