First question is - Why do we have limestone? Formed from this type of sediment are biological sedimentary rocks. Their biological organ is often revealed in the rock fossils. Some limestones can form by direct precipitation of calcium carbonate from marine or fresh water. (The second question is) - What do iron bands mean? The rocks are "banded" because the iron minerals deposited in alternating bands with silica and sometimes shale. The banding might have resulted from seasonal changes in organism activity steel mill. Most iron ore is used to make steel. Here a steel slab is being cut to length in a steel mill.
Answer: mutualism
Mutualism is a symbiotic relationship, between two organisms, living in close association with each other. In this relationship both the organisms gains benefit. Both organisms are dependent on each other for competing their life cycle.
The given situation is an example of mutualism because both the species are benefited for the relationship. Birds receive food from strawberries in turn birds disperse the seeds of strawberry to promote growth of more strawberry plants. Both organisms are interdependent on each other.

Answer:
- Pol III binds to 3' end of primer B
- Poll III moves to 5' to 3',adding DNA nucleotides to primer B
- Pol I binds to 5' end primer A
- Pol I replaces primer A with DNA
- DNA ligase links fragments A and B
Explanation:
Both strands of parental DNA acts as a template for the synthesis of new DNA. The site of synthesis is called replication fork because the daughter strands look similar to <em>two-pronged fork.</em> The strands formed from Okazaki fragments(short sequences of DNA nucleotides) is called the <u>lagging strands,</u> which is synthesized in short fragments and in the opposite direction. While the strand that is synthesized continuously and in the same direction as the movement of the replication fork is called the <u>leading strand.</u> Both strands are synthesized in a 5'→3' direction. DNA ligase join these fragments together.
