1. tetrapods are ( four-limbed animals ) . examples of tetrapods include (extanct and extinct amphibians , reptiles , and mammals )
2. Tetrapods first appear in the fossil record ( 367.5 ) million years ago .
3. Charles Darwin predicted that tetrapods evolved from ( a finned organism that lived in the water) . What observation leads do that hypothesis?( they have “fleshy fins” and “lobe fins”) .
5. Fish use ( gills ) to breathe underwater .
Cell division occurs in all living organisms. This is known as mitosis.
The advantages of a larger organisms to subdivide themselves into smaller cells is that as all organisms grow, some of their cells die or get damaged with time and need replacements. So,it divides into smaller cells because when a cell becomes large, it demands more of cell places of its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. So to grow properly the cells need to be divided.
Sugar production would stop meaning the plant doesn't have the needed nutrient to make food for itself causing another factor : photosynthesis to stop aka the plant would die and wither
Answer:
Explanation:
This question is incomplete. However, what is described in this question is a method of DNA damage repair mechanism. The method described is called base excision repair. Generally, glycosylases play important roles in base excision repair (as they detect and remove these damaged bases).
One thing that can be considered while identifying the bond to be broken is the codon that will be formed after the removal of base. If this codon (a three base sequence) will still produce the same protein as when a normal cytosine was present.
NOTE: During this base excision repair, a glycosylase will detect and remove the damaged cytosine. Once removed, the remaining nucleotide backbone (of the removed cytosine) is also removed and the gap is filled and sealed by other enzymes in this repair mechanism.
