Epiphyseal plate is the structure within a bone that contains cartilage
cells that divide and increase the size of the bone until adulthood.
The epiphyseal plate, also known as epiphysial plate,or physis, or growth plate, is a hyaline cartilage plate in the metaphysis at each end of a long bone or diaphysis. The plate is found in children and adolescents; in adults, who have stopped growing, the plate is replaced by an epiphyseal line<span>.</span>
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.
Answer:
The correct answer will be option-E.
Explanation:
Chordae tendinae are the string-like structure in the heart which is composed of dense regular connective tissue called collagen and elastin proteins. They arise from the papillary muscles of the heart and branches out in the ventricle portion of the heart.
These play an important role in the closure of the AV valves to prevent the backward flow of the blood to the atria during ventricular contraction by holding cusps of the valve into the dome-shaped structure.
Thus, option-E is the correct answer.
