Answer and Explanation:
In some, the leaves are needle-like and stomata are reduced in number and located in cavities on the epidermis. A layer of moist air builds up in the cavity. This reduces the humidity difference between the intercellular air spaces in the leaf and the immediate external environment thus reducing the rate of transpiration.
In some the epidermis of the leaves is multilayered and is covered with a thick waxy cuticle which reduces water loss through evaporation, e.g. oleander. The cuticle is normally shiny which helps to reflect solar radiation preventing the leaf from heating up rapidly.

Answer:
Frog forelimbs are typically short as the hind limbs are the principal limb pair generating propulsion.
Polygenic inheritance is determined by multiple Genes <span>located at different loci on different chromosomes.
Polygenic inheritance happens when an individual posses quantitative traits that become a variation compared to the parent's traits.
This phenomenon happens due to the combination of two or more genes that resulted in the characteristics that considered as the combination of both parents' characteristic.
