The skin contains stratified squamous epithelium and an underlying layer of areolar tissue. What structure is found where the two tissues come together? O goblet cell O basement membrane O cilia apical surface QUESTION 17 Epithelia are avascular. This means that O epithelia contain very little extracellular material, o epithelial tissues have a high capacity for regeneration. o epithelial tissues have an apical surface and a basal surface. O epithelial tissues do not contain blood vessels QUESTION 18 Which of...
Bonus question (3 points possible): In a flowering plant the a/a; B/B genotype results in yellow flowers, and the A/A, b/b genotype gives red flowers. Wild-type flowers are orange and are observed in plants with genotype A/A; B/B. Two possibilities have been proposed for the biosynthetic pathways of flower color: 1] yellow pigment red pigment 2) red pigment → yellow pigment orange pigment orange pigment Propose a genetic experiment that can determine which of the two possibilities is most likely...
