All variations within organisms can be explained by the known principles of genetics. True or False

Fynjy0 [20]

Answer:

The statement is true.

Explanation:

Genetics is responsible for studying the way in which the characteristics of living organisms, whether morphological, physiological, biochemical or behavioral, are transmitted, generated and expressed, from one generation to another, under different environmental conditions, that is, try to explain how the characteristics of living beings are inherited and modified, which can be in shape (the height of a plant, the color of its seeds, the shape of the flower...), physiological (for example, the constitution of certain protein that performs a specific function within the body of an animal), and even behavior (in the form of courtship before mating in certain groups of birds, or the way of mating of mammals, among others). In this way, the principles of genetics tries to study how these characteristics pass to generation after generation, and why, in turn, they vary generation after other.

Can we detect bacteria in pollutants using DNA profiling

Blababa [14]

Yes. You could do this by adding solvents to break down any cell walls, centrifuge to separate the DNA, if you haven't got much then upscale with PCR, gel electrophoresis could be used to detect the DNA, and Sanger sequencing to find the sequence.

The large population of microbes that contribute to the gut microbiota and have an important role in food processing are called:

postnew [5]

The large population of microbes that contributes to the gut microbiota and have an important role in food processing are called <u>Commensal microorganisms</u> .

The human body is host to trillions of microbes or bacteria. Most of these are useful but may become harmful when out of control.

The microbiota consists of a wide variety of bacteria, viruses, fungi ,and other microorganisms present in a singular environment such as the human digestive tract.

<h3>Gut microbiota : </h3>

The gut microbiota is vast and complex collection of microorganisms that profoundly affects human health gut microbiota are present in the digestive tract of vertebrates including humans.

The function of gut microbiota in body function includes harvesting energy from digested food, protecting against pathogens, regulating immune system and strengthening biochemical barriers of the gut and intestine changes in microbiota composition can affects these functions.

The normal gut microbiota have specific functions like host nutrition metabolism, maintenance of structural integrity of the gut mucosal barrier, helps in immunity, protect against pathogens.

<h3>Commensal microorganisms:</h3>

Commensal microorganisms are those type of microbes that reside on either surface of the body or at mucosa without harming human health . commensal bacteria are 10 times more than the cells present in our body.

Example - Streptococcus oralis and Streptococcus salivarius .

Commensal microorganisms plays an important role against pathogens including respiratory pathogens. It acts on the host's immune system to induce protective response that prevents colonization an invasion by pathogens. On the other hand these bacteria can directly inhibits the growth of respiratory pathogens by producing antimicrobial products .it also competing for nutrients and adhesion sites. Provides the host with essential nutrients.

<h3>What are microbes ?</h3>

Microbes are tiny living things that are found all around us and are too small to be seen by eye. They live in soil, water and in air. The human body is the home of trillions of microbes.

Julie wrote down the list below of the reasons why she thinks that humans should stop relying on fossil fuels.

forsale [732]

Julie listed out fossil fuels are a non-renewable source of energy and Fossil fuels are becoming more expensive.

Option C

<h3><u>Explanation:</u></h3>

Fossil fuels are defined as the type of non renewable energy which is formed as a result of dead and decaying organic matter over thousands of years under pressure and temperature of Earth’s core.

This type of fuels are formed due to the dumping of dead prehistoric organisms like dinosaur and others under the soil under a tremendous pressure and very high temperature, where they are acted upon by bacteria and other chemicals to reduce them into petroleum and coal. These are totally non renewable and they are getting expensive over days due to shortage of availability.
