Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.
Explanation:
Reforestation of agricultural land can improve biodiversity, which can result in increased primary production, reduced susceptibility to invasion by exotic species and increased ecological resistance to pressures such as climate change
<span>Apart from their habitats, Bacteria and Archaea differ in cell wall structure and membrane lipid composition. All bacteria have peptidoglycans in the cell wall whereas the archaea do not. Both also are different in RNA polymerases and thus in their protein synthesis. </span>
C. A new source of freshwater
Explanation:
The situation that would most likely increase the carrying capacity for humans in a certain region is the availability of new sources of freshwater.
In ecological terms, the carrying capacity of a place is the the number of people, animals, or crops which a region can support without environmental degradation.
- A new source of freshwater provides new resources for the ecosystem.
- In the freshwater, more fishes are available, more plants can grow around and a lot of biological activities can progress.
- Water is essential for life.
- Fresh water sources are incentives for choosing to live in a place or not.
- A fresh water source increases the carrying capacity for humans in a certain region.
