Cactus because they have visible leaf modification that preserves water for a long time in dry conditions
Quantitative measurements are those that deal with a quantity, for example:
Mass of as sample
Length of a piece of wire
Molecules in a mole
Volume of a gas
Temperature of a sample
These types of measurements are called Extensive.
Qualitative measurements are those that deal with the quality, for example:
Color of a sample
Texture of a surface
Coarseness of a powder
Aroma of a reaction
Malleability of a metal

The correct answer is calcification zone.
A hyaline cartilage plate in the metaphysis at each terminal of a long bone is known as the epiphyseal plate or the growth plate. It is the section of a long bone where the development of new bone occurs.
The epiphyseal plate exhibits a very specific morphology in possessing a zonal arrangement. One of the zones is the zone of calcification, in this, chondrocytes goes through the process of apoptosis and cartilaginous matrix starts to calcify.
