The arrow representing the activation energy will decrease in magnitude.
This arrow will be beginning at the x-axis and going up to the maximum of the graph. The reason that its magnitude decreases is because enzymes provide alternate pathways to reactions; the new pathway has a lower activation energy, so the reaction occurs faster when an enzyme is added. This is why enzymes are referred to as biological catalysts and are a vital part of an organism's body
Answer:
The correct answer is statement b.
Explanation:
This is due to the fact that the reduction of the vast majority of forest land, that is, mainly in Brazil has resulted in the extinction of the unknown and the familiar species. This has also declined the biological diversity and thus has immensely affected the fertility of the soil.
The soil has turned shallow and thus are less fertile in comparison to the Mid-Western United States. The Midwestern parts of the United States possess variety of soils, which are produced due to the glacial deposits and thus provides more fertility to the soil.
Answer:
False
Explanation:
In the troposphere, near the Earth's surface, human activities lead to ozone concentrations several times higher than the natural background level. Too much of this ground-level ozone is 'bad' as it is harmful to breathe and also damages vegetation.
The stratosphere or “good” ozone layer extends upward from about 6 to 30 miles and protects life on Earth from the sun's harmful ultraviolet (UV) rays.
