catalyzed particular chemical reactions – in this case, reactions that broke down the film of eye goo that accumulated on my contacts after a week of use. (Presumably, the reason it stung when I got it in my eyes was that the enzymes would also happily break down eye goo in an intact eye.) In this article, we’ll look in greater depth at what an enzyme is and how it catalyzes a particular chemical reaction.
Enzymes and activation energy
A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

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.

Why do cells continue to divide in adult organisms?
Answer:
Although most of the tissues in adult organisms maintain a constant size, the cells that make up these tissues are constantly turning over. Therefore, in order for a particular tissue to stay the same size, its rates of cell death and cell division must remain in balance.

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

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.

Answer:
Chemical weathering and physical weathering.
Explanation:
Green anoles predominantly thrived on the full of greenery and less competitive island and have developed shorter legs and bigger bodies, while brown, long-legged, small-bodied anoles thrived on the treeless and competitive mainland. Scientists hypothesized that speciation (2 new species) occurred. Explain how that happened using evidence provided and what you know about speciation.
Answer:
Anolis is involved in the two green and brown species of anole speciation processes. Speciation is the process caused by evolution that results in the development of collective genetic changes during a period of time due to adaption or geological or environmental conditions.
The evolution of these two species is due to the difference of the niche or geological difference likewise here the niches of both green and brown Anoles among species in relative size as well as color and pattern.
