Answer: The correct answer is 3) A segment of a DNA molecule that contains  the instructions for producing a trait in an  organism.

Gene is a segment of DNA molecule that contains instructions ( in the form of nucleotide sequences), which are required for producing a specific trait ( characteristic) of an organism.

For this, gene is first transcribed into mRNA ( messenger RNA), which is then translated to produce a particular protein. The protein thus formed gives a specific characteristic to the organism.

Thus, option 3) is the best description for a gene.

olasank [31]

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.
