The Hubbard Brook watershed deforestation experiment yielded all of the following results except b. Calcium levels remained high in the soil of deforested areas.

Deforestation is the purposeful clearing of forested land. during records and into modern instances, forests have been razed to make space for agriculture and animal grazing and to attain timber for fuel, production, and construction. Deforestation has greatly altered landscapes around the sector.

Deforestation or forest clearance is the removal of a wooded area or stands of trees from land this is then transformed into non-wooded area use. Deforestation can involve the conversion of forest land to farms, ranches, or for city use. The maximum concentrated deforestation takes place in tropical rainforests.

The bond types that may be utilized to establish the tertiary structure of a protein are the non-covalent bonds.

The tertiary structure of a protein is the arrangement of a protein in the three dimensional space. It is stabilized by the non-covalent bonds. It is the level of protein structure where a protein becomes functional. The example of protein which is functional in tertiary structure is myoglobin.

Non-covalent bonds are those that are formed between different molecules rather than the atoms. No sharing of electrons occurs in this type of bonding. The examples of these bonds are: ionic bonds, hydrogen bonds, Van der Waals forces, etc.

In the late 1800s and early 1900s, during the climax of the American Industrial Revolution, there was a small group of men who owned the major businesses and were leaders of their industries.  They owned factories, railroads, banks, and even created company towns for the sole purpose of housing their workers.  Due to the efforts of these few men, the U.S. economy became the envy of the world, and America became a leading world power.  They provided the public with products that were in high demand for reasonable prices, and opened their markets to countries overseas.  Although many people believe the early industrialists were Robber Barons who exploited the poor, these great men were truly Captains of Industry who created new ways of doing…show more content…Although some of these criticisms are well founded, men like Andrew Carnegie and John D. Rockefeller were, in fact, Captains of Industry because they employed millions and created new ways of doing business.  Before all these industrialists can along, America was just another country that had little significance to the world.  If it was not for them, we as a nation would not be where we are today.  The industrialists prospered mainly due to their wit, and the many innovations that they brought to their various fields of business.  They created monopolies because they were the most effective forms of enterprise, and there were no laws that prohibited or restricted their use.  As John D. Rockefeller himself said, "I believe in the spirit of combination and cooperation when properly conducted.It helps to reduce waste, and waste is a dissipation of power."(Danzer 424)  Critics say that these men ruthlessly took over their fields of business, and "did not play fair".  What's wrong with striving for success?  What's wrong with being efficient? What's wrong with making a product that no one can equal?  What's wrong with besting your competitors?  Nothing.

The aquaporins are channel proteins that form cylindrical shape, being embedded across the whole membrane. Since the protein crosses the entire membrane, it must have hydrophilic polar amino acids at the top and bottom whereas, the integral part of the channel must have hydrophobic amino acids on the outer side and hydrophilic amino acids on the inner channel side.

Aquaporins are the channel proteins that mediate the transport of water molecules across the membrane from its region of higher concentration to the region of lower water concentration, i.e. passive transport. They can also transport some very small solute particles.

Channel proteins are those involved in passive transport. They do not undergo any conformational change to transport the molecules.

The oxygen created during photosynthesis comes from water, not carbon dioxide.

By 1940, chemists began employing heavy isotopes to track photosynthetic processes. Early investigations employed water labeled with an oxygen isotope (18O). Plants that photosynthesized in the presence of H218O-containing water generated 18O-containing oxygen gas; plants that photosynthesized in normal water produced normal oxygen gas. These findings confirmed van Niel's notion that the oxygen gas created during photosynthesis is obtained from water.

Van Niel's proposal (that oxygen produced during photosynthesis originates in water rather than carbon dioxide) was significant because the popular (though invalid) theory was that oxygen was removed from carbon dioxide (rather than hydrogen from water, releasing oxygen) and carbon was then combined with water to form carbohydrate (rather than the hydrogen from water combining with CO2 to form CH2O).

The independent variable is the variable that changes.

An independent variable is one that you adjust, control, or modify in an experimental study to look at its consequences. Because it is unaffected by any other study variables, it is called "independent."

The independent variable in an experiment is the thing you modify, and the dependent variable is the thing that changes as a result of the independent variable.

This is an easy way to conceive of independent and dependent variables. The independent variable can alternatively be viewed as the cause, and the dependent variable as the result.

Predictor variables are another name for independent variables. This is so that changes in reaction can be "predicted" and explained using this variable. For instance, an independent variable like the amount of fertilizers can help us to know how much plant growth will occur.
