Scientist use data from gregor mendel‘s studies to conclude that information about traits is passed from parents to offspring through

The correct answer is genes.  

A trait refers to the feature like size or color, which is passed from the parents and is inherited by the offspring. The genes control traits and come in pairs, that is, one gene from each parent.  

The transmission of hereditary traits possesses its molecular framework in the accurate DNA replication. This generates gene copies, which can be transmitted to the offspring from the parents. In plants and animals, the reproductive cells known as gametes are the mediators, which transfer genes from one generation to the next.  

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
