Answer: Similarities in amino acid sequence strongly suggest common ancestry
Explanation:
The chemical make-up and biochemical process of all organisms are as very similar. For example, all organisms
- are build up of the same types of complex molecules such as carbohydrates, lipids, proteins (polymers of amino acids) and nucleic acids
This similarity strongly suggest common ancestry for all organisms, thus leading to evolution of individual species
The correct answer is option C, that is, woody, reinforced cell walls.
The prime layer of growth in the roots and stems of various plants, mainly in dicots like oak trees and buttercups, and gymnosperms like pine trees is known as vascular cambium. It generates phloem on the outside and xylem on the inside.
The vascular cambium thickens stems or branches and increases their girth. Thus, due to their unique tendency, one would expect vascular cambium to be simple, undifferentiated cells, which possesses the tendency of rapid cell differentiation, but would not expect them to have woody, re-inforced cell walls.
