Question 45 (2 points) Most plants do best in soils with a pH that is above 10 between 8 -10 below 2 between 6 and 8 Question 46 (2 points) Which of the following represents the greatest conservation of the genetic bank? all of the varieties of corn, wheat, and rice that are crops. thef proteomics, investigating the many ways the proteins function in the human genome center, analyzing the components of the human genome seed banks that store seeds of thousands of plants from around the world Question 47 (2 points) If water is depleted from an aquifer faster than the recharge rate. sinkholes may form the water table will rise wetlands will flood surface woter will stop percolating downward then

Let's analyze each question step by step: ### Question 45 **Most plants do best in soils with a pH that is:** - **above 10**: This is too alkaline for most plants. - **between 8 - 10**: This is still considered too alkaline for most plants. - **below 2**: This is extremely acidic and not suitable for most plants. - **between 6 and 8**: This range is generally considered optimal for most plants, as it is close to neutral pH. **Answer:** **between 6 and 8** ### Question 46 **Which of the following represents the greatest conservation of the genetic bank?** - **all of the varieties of corn, wheat, and rice that are crops**: This represents a significant portion of agricultural biodiversity but is limited to specific crops. - **the proteomics, investigating the many ways the proteins function in the human genome**: This is related to human genetics and does not pertain to plant genetic conservation. - **seed banks that store seeds of thousands of plants from around the world**: This represents a comprehensive approach to conserving genetic diversity across many plant species. **Answer:** **seed banks that store seeds of thousands of plants from around the world** ### Question 47 **If water is depleted from an aquifer faster than the recharge rate:** - **sinkholes may form**: This is a possibility as the ground can collapse when the water is removed. - **the water table will rise**: This is incorrect; the water table would actually drop. - **wetlands will flood**: This is unlikely; wetlands may dry up if the aquifer is depleted. - **surface water will stop percolating downward**: This could happen, but it is not the most direct consequence. **Answer:** **sinkholes may form** ### Summary of Answers - **Question 45:** between 6 and 8 - **Question 46:** seed banks that store seeds of thousands of plants from around the world - **Question 47:** sinkholes may form
