One method is to microinject deoxyribonucleic acid (DNA) into eggs; another method is to use vortex mixing to create tiny holes in the eggs through which DNA enters.
<h3>Process of gene transfer</h3>
Genetic engineering techniques are steps that are taken to create a genetically modified organism that can be used for studies. This technique involves the following major steps:
- Isolation of DNA fragments from a donor organism,
- The insertion of an isolated donor DNA fragment into a vector genome; and
- The growth of a recombinant vector in an appropriate host.
The insertion of an isolated donor DNA fragment into a vector genome can be done through microinjection method or vortex mixing.
When eggs are used as vector genome, microinjection of DNA can be carried out or vortex mixing can be used to create tiny holes in the eggs through which DNA enters.

The answer is germination :)
The hatchery bred salmons do have different traits as compared to the wild salmons because of the environmental effects it does have on their maturity.
Option B.
<h3><u>Explanation:</u></h3>
The wild varieties of salmons do live in natural streams and rivers and do have to collect their own food themselves. They face the struggle for their existence as well as they have to compete with each other for getting food. So their adaptation is very high and specialized.
Whereas the hatchery bred salmons get their food from what is supplied to them. They get perfect conditions for living artificially. They also doesn't face wild traits of diseases which do often attack the wild varieties, so lacks the immunities against them. Thus these differences lead to the different traits between them. Thus they cannot survive together and it will lead to a divergent evolution, or the survival of the fittest and natural selection will eliminate the hatchery bred varieties because if their incapabilities.
Cells divide for growth, to repair tissue damage, and because the nucleus can only control a certain size of cell.
Hi there!
If a substance is organic, it burns rapidly.
Since, for example, carbon is organic matter, it has chemical reactions and burns when having contact with oxygen (creating carbon dioxide).
Similarly, many organic matter burns when having a reaction.
Hope this helps!
