Answer:
It is the process where by plants manufacture their own food by using raw material such as carbon (iv) oxide, water and sunlight.
To identify people by DNA it is better to make copies of non-coding segments because they exhibit more variation than genes.
- The polymorphic sequences of non-coding DNA vary between individuals in humans.
- Variable number tandem repeats, or VNTRs, are created when DNA sequences are repeatedly replicated in the genome's non-coding regions.
- It is possible to create a person's genetic fingerprint by counting the amount of repeats, which varies between individuals.
- However, this non-coding DNA is used in criminal investigations by forensic experts.
- There are distinctive repeating patterns found inside this area of DNA that can be utilized to distinguish one person from another.
- Short tandem repeats (STRs) are a type of pattern that can be measured to determine a person's DNA profile.

Answer;
-The bacterium would exhibit positive chemotaxis.
Explanation;
-Chemotaxis is the movement of cells or organisms in response to chemicals, whereby the cells are attracted (positive chemotaxis) or repelled (negative chemotaxis) by substances exhibiting chemical properties.
Flavonoids play a crucial role as signal molecules in promoting the formation of nodules by symbiotic bacteria commonly known as rhizobia. The roots of leguminous plants use positive chemotaxis to attract rhizobia. Flavonoids are the chemicals associated with attraction of Rhizobium bacteria.
