The skill of connecting gathered data with information that is known to us is called data analysis. This is a key part of the data analysis process. Example:
It is a fact that foxes are known predators of rats. Lets say you have a data table or observation table that shows the increase in number of rats in your locality versus the increase in the number of fox being spotted by the residents. Now based on the fact that you know, a relation can be established between the increased fox sightings and increase in rat numbers.
Answer:
The preferable words for the fill in the blanks will be -
Aragonite, calcite
Explanation:
- Biogenic minerals are minerals produced by living organisms. Two commonly seen biogenic minerals are <u>aragonite</u>, which is often produced by coral and other invertebrates, and <u>calcite</u>, which often makes up the shell material of mollusks such as clams.
- Biogenic minerals are the mineral substances that are produced by geologic processes. For living organisms, it is their most commonly produced byproduct.
- E.g; vertebral bones, shells of Oyster, mussel, and clam (aragonite), etc.
Answer: A hypothesis can become <u>a scientific theory if it is supported by repeated experimentation. </u>
Answer:
The leading strand is copied in the 5' to 3' direction and the lagging strand is copied in the 3 to 5 direction.
Explanation:
1. The original DNA molecule remains intact, although it acts as a template for the formation of a copy that contains two new antiparallel strands. - this is false.
DNA replication is said to be "semi conservative". This is because in making a new DNA molecule, one of the strands is from the original DNA molecule and one is new. This is true for each new molecule produced One DNA molecule makes 2 new molecules, each containing one of the original strands
2. The leading strand is copied in the 5' to 3' direction and the lagging strand is copied in the 3 to 5 direction. This is true. The synthesis of each strand occurs through a distinct mechanism. The leading strand is synthesised 5'-3' (towards the replication fork), and the lagging strand is synthesised from 3'-5', away from the replication fork. T
he leading strand is synthesised continuously using an RNA primer to begin the process. The lagging strand is synthesised discontinuously, with several short primer sequences permitting the synthesis of short fragments (Okazaki fragments) that are later joined by DNA ligase. <em>NB: this is easy to remember if you consider that </em><em>3 lags behind 5</em>
3. Both strands are copied to form Okazaki fragments, which are later annealed by DNA Ligase. This is false. Only the lagging strand replicates to form Okazaki fragments
4. The replication process proceeds on both strands in the same direction, which requires that RNA primers bind to the lagging strand. This is false. The strands are synthesised in different directions
