The correct answer is: c.)Bilaterally symmetric animals can be streamlined for swimming, but radially symmetric animals cannot.
In radial symmetry the body can be divided by several cutting planes that produce roughly identical pieces. Organisms with such symmetry are usually cylinder, with no left or right sides only top and a bottom surface. Radial symmetric organisms are symmetrical about an axis that goes from the center of the oral (top) surface, to the center of the opposite (bottom) end. It is suitable for sessile animals or slow moving animals.
In bilateral symmetry one plane can divide an organism into roughly mirror image halves (the right and left halves). One of the advantages of the organisms with bilateral symmetry is the streamlining of the body.
Answer:
The regularity of DNA's overall structure.
Explanation:
DNA is the genetic material of almost all the living organisms but RNA may also acts as the genetic material in some viruses only. The mutation in DNA may cause characteristic disease in individual.
The nucleotide excision repair mechanism excise the wrong nucletide and replace with the correct nucleotide. The overall DNA structure like its nucleotide sequence, the size and angles between the DNA base pair, its methylation helps in recognizing different DNA type.
Thus, the correct answer is the regularity of DNA's overall structure.
Answer:
6 inches
Explanation:
Area = length x width. So width = area/length and then 216/36 = 6.
The cardiovascular system has three main functions:
transport of oxygen, carbon dioxide and nutrients.
clotting of open wounds.
regulation of body temperature.
