Because DNA must have guanine to balance it out, without guanine the percent of adenine would increase.
Answer:
All plants and animals need nitrogen to make amino acids, proteins and DNA, but the nitrogen in the atmosphere is not in a form that they can use.
Explanation:
When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.
Fault-block mountains are formed when two tectonic plates collide, pushing oneover the other. Upwarped mountains form when a "hot spot" of magma pushes upward <span>through the earth's crust.</span>
Answer: All of the above.
Explanation: Inflammation process is part of the immune response to fight against infection or injury. It works together with the complement system that promotes the ability of antibodies and phagocytes to remove microorganisms and damaged cells from site of infection. Cytokines are produced by T-helper cells and macrophages to regulate inflammation by producing cytokines that sends positive feedback for the initiation of inflammation process. Promoting the production of chemicals, proteins and enzymes for chemotaxis and diapedesis of phagocytes.
Basically during inflammation the site of infection or injury will change colour and turn red, it will swell and cause the production of pyrogens which will result in fever symptoms due to raise of body temperature.
Bacteria only:
The separation of chromosome initiates at the origin of replication of DNA.
Eukaryotes only:
Prior to separation, the duplicated chromosomes condense.
Nuclear envelope fragments allowing the separation of the chromosome.
Two copies of the duplicated chromosome are combined with their centromeres prior to separation.
Both bacteria and eukaryotes:
The replication of chromosomes takes place before cell division.
Replicated chromosomes separate by attaching to some other structural characteristic of the cell.
