The vector, which is often a small, circular piece of dna that can exist outside the bacterial chromosome, is known as a plasmid.
Bacteria and certain other microscopic species contain plasmids, which are tiny circular DNA molecules. Physically distinct from chromosomal DNA, plasmids multiply on their own. They normally contain only a few genes, including some linked to antibiotic resistance, and they can spread from one cell to another.
Recombinant DNA techniques are used by scientists to splice the genes they want to research into a plasmid. The inserted gene is duplicated along with the plasmid when it duplicates itself. Molecular cloning, the process of creating DNA molecules and introducing them into a host cell, uses plasmid vectors as the means of delivering recombinant DNA into the host cell.

Fault-block mountains form when Earth's crust pushes material up and down near a fault line.<span> Rocks that get pushed upward eventually form mountains if there is enough seismic activity. The higher part of a fault-block area is called a horst, while the lower part is called a graben, according to Ducksters.

Answer: long bones
Explanation:
The long bones are the kind of bones which are slightly curved. These bones are curved this way these bones absorb the maximum external stress applied on the body from several points. They comprise of long, thin part that is called as the diaphysis, a shaft and two bulbous type ends that are called as the epiphysis. These consists of compact bones. These bones are hard, dense, and thus these bones provide the strength, mobility and structure to the body.
Answer:
This is a hint, In ecology, a population consists of all the organisms of a given species that live in a particular area. The statistical study of populations and how they change over time is called demography. Ecologists often estimate the size and density of populations using quadrats and the mark-recapture method.
Explanation:
Hi :)
There are two types of dichotomous keys, one is a spider key
and the other asks a series of questions and as you answer them, depending on the characteristics of your species, you’ll decide what step to move to
Hope this helps :)
