DNA sequencing technique runs through database so it can compares all the sequenced information and finds similarities.

Every pathogen either virus or bacteria has its own specific DNA and DNA sequencing recognizes similarities while study sequence of nucleotide.

Further explanation

DNA sequencing

It is a phenomenon in which a piece of DNA is taken and its nucleotide bases (guanine, adenine, thymine and cytosine) are determined. It is useful to study genetic information of an organism. Earlier technique of RNA sequencing was used.

Invention of DNA sequencing

Frederick Sanger was the first person who used this technique and was invented in 1970s. This technique is used in various field of biology such as molecular biology, Medicine, evolutionary biology, biotechnology and forensics.

Advantages of DNA sequencing

 It provides accurate information

 Genome remains same throughout life so it is done once in life

 It is not an expensive method so we can say that it saves money

 Genomic information can be obtained which is required for various purposes as health care

 Identify defective genes

Disadvantages of DNA sequencing

 It is a very time taking technique

 It cannot detect translocation, deletion and insertion

15,000 years ago, when humans were foragers and hunters, what characterized daily life? What were humans eating, and where and h

lisabon 2012 [21]

1. 15,000 years ago the humans were still hunter-gatherers. Their daily lives were largely based around one thing, finding enough food to survive through the next few days. This means that they had to constantly be on the move, be it for hunting animals, or for finding rich places with eatable plants. There was lot of walking, running, and scouting involved every day. It was a lifestyle of ''living through the day''.

2. During this period of time, the diet of the humans was consisted of animals they hunted, fish, and plants. There were differences from region to region though, so the people that lived along the coastline based their diet on marine animals, the ones that were living in colder regions were eating mostly meat, while the ones living in forested areas or grasslands had combination of plants and meat. The lifestyle in general was moving from place to place, be it on a daily basis, weakly, or seasonally, depending on the conditions. Some of these people were making small shelters, some of which were retractable and they were moving them with them, while others were using caves.

3. There are many difference between the forager peoples and the agriculturalists. The foragers were nomads, thus they were moving very often from one place to another, while the agriculturalists were having a settled lifestyle. The nomads very often had bad injuries which were often fatal, usually because of hunting, while the agriculturalists had much better health because they had much safer lifestyle. The foragers were not able to produce their own food, but instead they were relying on mother nature, while the agriculturalists were producing their own food and had the food problem solved.

What conclusions can be drawn about the existence of carbon-12, carbon-13, and carbon-14? A) These are forms of carbon and they

Kryger [21]

Answer:

Explanation:

All these carbon atoms are isotopes: they have the same amount of protons (in this case, 6 because carbon always has 6 protons) and the same amount of electrons (6 because the carbons given have a neutral charge).

Therefore, the only thing we are changing is the atomic mass and the amount of neutrons present in each isotope.

In Carbon-12, there are 6 protons, 6 neutrons, and 6 electrons.

In Carbon-13, there are 6 protons, 7 neutrons, and 6 electrons.

In Carbon-14, there are 6 protons, 8 neutrons, and 6 electrons.

Effectus [21]

Answer:

The correct answers are:

1. closing

2. the ventricles and arteries,

3. a constricted trachea

Lub is the first sound of a heartbeat and is mentioned as S1. It is usually produced due to the closing of tricuspid and and mitral or bicuspid valves present between atria and ventricles.

Tricupsid is located between atrium and ventricle of the right hand side and mitral valve is located between atrium and ventricle of the left hand side. They prevent the back flow of blood from ventricles to their respective atria.

Dub, being the second sound is written as S2. It is produced due to the closing of pulmonary (located between right ventricle and pulmonary artery) and aortic valves (located between left artery and aorta).

These valves prevent the back flow of blood from arteries into the ventricles.

The time between the two sounds is often taken as the measure of the diastole i.e. ventricular filling.

Wheezing refers to a high-pitched sound produced when a person breathes, especially during exhale. It is caused by constriction of the airways or inflammation. It is considered as a symptom of various diseases such as asthma, COPD, allergies, bronchitis etc.
