Specialisation in the knowledge society and its need

Posted by Bernardo Lajus on Mon, 01/07/2013 - 11:54.

Contemporary society is characterized by globalization. The information and the speed with which they reach society amaze anyone who has experienced the 1980s and 1990s. Because of the technology and facilities it brings, the recipients of this information become increasingly demanding, in every way. Demanding with you, with others, with things, with everything, making the world so demanding, to the point that services and information are insufficient, exhausting, poor.

Because of this, the world specializes. The professions have gained new directions, new perspectives. The courses that were previously generic, such as engineering, law, medicine, became insufficient and were gaining tributaries. If before the general practitioners of mechanical engineering and law realized the professional demand, over the years and the evolution of society, it required professionals to become specialists, creating branches and opening possibilities.

Today, specialists, masters and doctors are essential for the rapid development of society, required everywhere. Despite the harm spawned (such as time demanded, or "knowing much about little), specialization in the knowledge society brings inegulable benefits. The creation of new jobs, the deepening of knowledge and the quality of services makes society evolve even more.

Thus, although the human being, in his individuality, is not expanding his way of knowing, but rather reducing himself to specificity, society as a whole plunges into a profound expansion of knowledge, bringing this to everyday life, from the most trivial to the most complex of works, specialization is necessary and beneficial.

how would you make an extract of a food to test for reducing sugar​

Answers

To test for the presence of reducing sugars, a food sample is dissolved in boiling water. Next, a small amount of Benedict's reagent is added and the solution begins to cool. During the next four to 10 minutes, the solution should begin to change colors. If the color changes to blue, then no glucose is present. If a high amount of glucose is present, then the color change will progress to green, yellow, orange, red and then a dark red or brown.

Which organelles must work together to provide food and energy to a plant cell?

Answers

Answer:

Mitochondria are the working organelles that keep the cell full of energy. In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose.

Chloroplast and mitochondria are organelles that must work together to provide food and energy to a plant cell.

Plants are living organisms that are capable of nourishing themselves from inorganic substances.

The complex chemical process by which they manage to do so is called photosynthesis and it takes place in chloroplasts.

Chloroplasts are elliptical-shaped organelles - their number varies between 20 and 100 in each plant cell - found in leaves and possessing the enzymatic machinery necessary to transform solar energy into chemical energy and, finally, into food.

The plant cell needs energy to grow and multiply and the mitochondria provide most of this energy by performing the last stages of the breakdown of food molecules.

Its main function is to supply the electron carriers (ATP), a product of cellular respiration, which provide the energy that the cell needs.

Therefore, we can conclude that within the leaves of plants, in the chloroplasts of plant cells, the chemical process that transforms inorganic matter into food takes place and the mitochondria are the energy-producing organelles.

What is chromosome ?

A chromosome is  a thread-like structure present in the nucleus of cells such as both prokaryotic and eukaryotic cell and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.

It is composed of three components, DNA, proteins and RNA,  amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.

Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).

The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome  is present in two forms such as Euchromatin and Heterochromatin.
