Separation of sister chromatids
I think it is true not 100% sure but i believe it is true <span />
I would say either C or D beside A say most living things are made of cells. No, all living things have cells. And B is right but C or D makes more sense.
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.
