A ribosome coordinates translation.
Answer:
Epidermal cells secrete the waxy hydrophobic substance cutin that polymerizes on the surface, forming a barrier to water evaporation. Epidermal cells are transparent because their plastids remain small and undifferentiated; hence light readily penetrates through to the photosynthetic tissues beneath the epidermis.

Answer:
More than one of the above
Explanation:
I strongly recommend sticking with the prescribed dosage of a drug.
A drug works by binding itself to the receptor site of a cell or tissue by non-covalent interactions.
Repeated doses of the same drug however may make the drug start behaving as an inverse agonist by blocking (instead of binding) the receptor site of the cell thus inducing a reduced response instead of an increased response to the drug.
Answer:
The best evidence for the three domain system is
Sensitivity to Antibiotics
Explanation:
The three domains of life includes :
Archaea - oldest known domain, ancient forms of bacteria.
Bacteria - all other bacteria that are not included in the Archaea domain.
Eukarya - all the organisms that are eukaryotic or contain membrane-bound organelles and nuclei.
Types of evidences for the three domain system are:
1) differences in the sequences of nucleotides in the cell's robosomal RNAs (rRNA)
2) the cells's membrane lipid structure.
3) its sensitivity to antibiotics.
