I think they are different in that they have jaws. Rays are predominantly marine and are found in all the oceans. Many are slow-moving bottom dwellers. They include, Manta ray which is one of the most known type of rays, Spotted eagle ray (pacific ocean), sting ray among others. They are about 15 types of rays in the oceans. Sharks, Lampreys and rays, like all fishes they are aquatic, water-breathing vertebrates with a brain and spinal cord, fins, plate-like pairs of internal gills, and paired sense organs.
Answer:
Explanation:
B) The pentose in the hairpin adopts only the C-3\' endo pucker conformation.
C) The hairpin adopts a right-handed helix with a diameter of 26 Å .
D) The hairpin contains G:C, A:U, and sometimes G:U base pairs.
DNA and RNA are both nucleic acids. Aside the structural difference of DNA being double stranded and RNA being single stranded, in DNA, the nucleotide bases adenine (A) is paired with thymine (T); while cytosine (C) is paired with guanine (G); howerver in RNA, thymine is replaced with uracil.; thus in RNA, the base pairs are - A:U and G:C
RNA however sometimes take on a dynamic structure, called the wobble case pair where guanine and uracil pair - G:U.
The diameter of RNA is 26 Å, while that of DNA is is 20 Å
The ribose in RNA with a helical structure has a C3’ endo conformation.
Answer:
B. Immune and circulatory
Explanation:
Maybe compare their performances in different environments, or try to compare their functions by way of situations such as placing them in sunlight and seeing which one lives the longest.
The answer is C.
The cytoskeleton in plants is responsible for cell shape, cell motility (movement) , and also motility of organelles within the cell.
The cytoskeleton connects to every organelle and every part of the cell membrane. The cytoskeleton in is a bit different from the human skeleton in that it is very dynamic meaning it can change shape, shorten or lengthen.
This dynamic nature is necessary for cells to change shape, complete cell division and migrate from place to another.
