Answer:
True
Explanation:
Because it teacher children how to behave
The factors are: The size of the sample, the extraction method, the method of purification and preservation of the DNA.
The quantity and quality of DNA can be greatly improved by performing PCR.
* Purification of nucleic acids is a key step for functional studies in biology. Because of the great diversity of living organisms in nature, purification becomes a real challenge for researchers, especially cell lysis.
The evolution of lysis methods has made it possible to improve efficiency, speed and simplicity. But, this lysis step remains a crucial step for the efficiency and the quality of the purification.
Decomposers eat dead consumers.
As these gases enter the atmosphere it thickens a layer over Earth which traps greenhouse gases and other gases that then leads to climate change because our hair is being clogged
So basically it’s a chain affect
Answer:
Lactose
Explanation:
Lac operon is a type of bacterial operon, characterized a cluster of genes regulated by a single promoter. It is usually contains an operator, promoter, a terminator, and three structural genes (lacA, lacY, and lacZ), which are responsible for lactose metabolism.
The lac operon is an inducible operon because it becomes activated in the presence of lactose.
