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 specialized parts are called lipid rafts, which is comprise
of hospholipase that are way too similar to each other and does not have
proteins which are linked with them. These are accountable for cell to cell
communication, gesturing, and acknowledgment.

Answer:
Cells are the basic units of life. Cells can exist by themselves, like bacteria, or as part of a larger organism, like our cells. Viruses are non-living infectious particles, much smaller than a cell, and need a living host to reproduce. The genetic material of the cell is DNA, a double stranded helix.
Explanation:
Question number 1.
The correct answer is: The insects are the same species.
There is still a lot of discussion in the scientific community on how should we define a biological species, but one of the main points that all scientists agree on is that the members of the same biological species are individuals that can successfully reproduce and leave viable and fertile offspring.
Question number two
The correct answer is : The graph showing directional natural selection.
In the case of the fish species of the coral reef, there are two extremes of the phenotype the dark orange and the pale one.
Before the bleaching of the coral, the dark orange phenotype was better adapted to the environment. But after the bleaching of the coral, the pale phenotype now resembles the coral background more and it is able to hide from the predators better than the dark orange one.
This will result in natural selection favoring the pale phenotype more and working in the direction of this extreme on the graph.
