Plasmids refer to a small molecule of DNA found within a cell that physically gets distinguished from a chromosomal DNA and possesses the tendency to replicate autonomously. The plasmids are generally found in bacterial cells in the form of small circular, double-stranded DNA. The plasmids are used commonly by scientists as the tools to manipulate and clone genes. The plasmids, which are used for these specific objectives are known as vectors.

The administration of the desired gene from one species to another has become possible with the help of plasmids. Thus, plasmids help in performing genetic modification. The procedure by which genetic makeup of a species is changed is called genetic engineering or genetic modification.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports the evolution of earth due to chemical weathering.

hope it !

The pharynx is the structure in the body that serves as a pathway of both air and food. how does the body make sure that food does not get into the lungs? the salivary glands secrete enzymes that pull food out of the air pathway. the small intestine pushes the air out of the digestive system. the pancreas breaks down food in the air pathway. the epiglottis closes the air pathway so that food will not enter it.
