Which activity enable humans to produce new genetic combinations in other organisms

It is the process of genetic engineering that allows humans to produce new genetic combinations in other living organisms. This is usually done by modifying the organisms DNA by either introducing or removing genes either chemically or by using a virus that splices the gene into the DNA of a host cell within the organism. 

The genetic engineering enables humans to produce new genetic combinations in other organisms. In this process, genetic material from one organism is taken and inserted into the DNA of other organisms. The transferred genetic material expresses itself in the other organism d desired characters are obtained.

When you're working with velocity vectors,
"west" is the negative of "east".

(395 East) + (55 West)  = 

(395 East) - (55 East)  =  340 km/h East.
