Explicación
## Step1For question 22, we need to identify the resources that can be renewed and are affected by an increase in human population. The options provided are trees and coal, oil and natural gas, water and gasoline, and water and trees. ## Step2Trees and water are renewable resources that can be replenished over time. Coal, oil, and natural gas are non-renewable resources, and gasoline is a derivative of oil. Therefore, the correct answer is water and trees.## Step3For question 23, we need to identify a factor that causes a growth response in plants. The options provided are an amino acid, a tropism, a stimulus, and a dicot. ## Step4A stimulus is a factor that causes a growth response in plants. Amino acids are building blocks of proteins, tropism is the growth of an organism in response to an environmental stimulus, and dicots are a type of flowering plant. Therefore, the correct answer is a stimulus.## Step5For question 24, we need to identify how desert plants have adapted to periods of water shortages. The options provided are storing excess water in the central vacuoles of cells, requiring less water than other plant cells, transpiring excess water from their stomata, and making their own water during periods of drought. ## Step6Desert plants have adapted to periods of water shortages by storing excess water in the central vacuoles of cells. This allows them to survive in arid conditions. The other options are not accurate descriptions of how desert plants adapt to water shortages. Therefore, the correct answer is storing excess water in the central vacuoles of cells.
