metals (left side of periodic table) become positive ions so calcium would be the answer
Answer:
electrical energy i believe
Answer;
A. the Sun's rays are nearly perpendicular to Earth's surface.
Explanation;
-Tropical region receives more solar radiation not only because the Sun’s rays hit the region more directly, but also because they travel through less of the atmosphere to get there.
-Some radiation is absorbed as it travels through the atmosphere, so less energy is lost in tropical regions.
The right answer is A. greater leaf surface area.
In botany and agronomy, the specific leaf area (SFS) is defined as the ratio of the leaf area to the dry weight of the leaf (expressed in m².kg-1).
The specific leaf area reflects the "thickness" of the leaves and has a particular physiological significance. This parameter is correlated positively with the photosynthetic capacity of the plant.
The specific leaf area can be used to estimate the reproductive strategy of a particular plant based on, among other factors, light and moisture levels. The specific leaf area is one of the most widely accepted key features used in the study of leaves.
