River power plants are not built in rows because the flow of a river is not consistent along its entire length. The power output of a river power plant depends on the volume and speed of the water flow, which can vary significantly from one location to another. Placing the power plants in rows would not be efficient as some plants would generate more power than others, leading to uneven distribution of electricity. Additionally, environmental factors and land availability also play a role in determining the placement of river power plants. **

River hydroelectric power plants are not being built in rows because the construction of multiple power plants in close proximity to each other can disrupt the natural flow and ecosystem of the river. Building power plants in rows can also lead to increased sedimentation and erosion, as well as potential negative impacts on fish migration and aquatic habitats. Additionally, the construction and operation of multiple power plants in close proximity can be logistically challenging and costly. Therefore, it is more sustainable and environmentally friendly to strategically place hydroelectric power plants along rivers to minimize ecological disruption. **

To regularly insert rows between existing rows in Excel, you can simply right-click on the row number where you want to insert a new row, and then select "Insert" from the drop-down menu. Another way to do this is by selecting the row where you want to insert a new row, and then going to the "Home" tab on the Excel ribbon, and clicking on the "Insert" button in the "Cells" group. You can also use the keyboard shortcut "Ctrl" + "+" to quickly insert a new row. These methods will allow you to easily add new rows between existing rows in your Excel worksheet. **

Yes, plants can be grown in pure pumice without soil. Pumice is a volcanic rock that is porous and lightweight, allowing for good aeration and drainage. This makes it suitable for growing plants as it provides a stable medium for root growth and allows for the exchange of gases and nutrients. However, it is important to note that pumice alone does not provide any nutrients to the plants, so fertilization and regular watering would be necessary for successful plant growth in pure pumice. **

In Excel, you can merge rows by selecting the cells you want to merge, right-clicking, and then choosing the "Merge & Center" option. This will combine the selected cells into one, centered cell. You can also choose the "Merge Across" option to merge cells in a row while keeping the cells in other rows separate. Additionally, you can use the "Merge Cells" option to merge cells without centering the content. **

In HTML/CSS, one can transform table columns into rows and rows into columns using the CSS property `display: flex;`. By applying this property to the container element of the table, the columns will be displayed as rows and the rows will be displayed as columns. Additionally, the `flex-direction` property can be used to specify whether the items should be displayed in a row or column layout. This allows for easy transformation of the table structure without changing the HTML markup. **
