State one of the goals of environmental science and why it is important.
telo118 [61]

Answer:

One of the major goals of environmental science is to understand and to solve environmental problems. In order to accomplish this goal, scientists study two main types of interactions between humans and their environment. One area of focus is on how we use natural resources, such as water and plants.

Explanation:

Environmental science is important because it enables you to understand how these relationships work. For example, humans breathe out carbon dioxide, which plants need for photosynthesis. Plants, on the other hand, produce and release oxygen to the atmosphere, which humans need for respiration.

Identify two examples of environmental factors that may impact salivary peroxidase activity. Describe how each of the environmen
charle [14.2K]

Answer:

Examples of environmental factors that may alter salivary peroxidase include periodontitis, oral hygiene, presence of heavy metal ions, bacteria (e.g., <em>Streptococcus gordonii</em>), anaerobic conditions, temperature, pH, etc.

Explanation:

Peroxidase is an enzyme found in all aerobic cells that act to convert toxic hydrogen peroxide (H2O2) into dioxygen (O2) and water (H2O). This enzyme plays an important non-specific defensive role against proliferating micro-organisms that cause periodontal diseases such as periodontitis, which is a serious inflammatory disease affecting the tissues around the teeth. The most common environmental factors influencing the development of periodontitis include oral hygiene, smoking and age. In this regard, it has recently been shown that there is a positive correlation between salivary peroxidase activity and periodontal health, especially in non-smoker individuals. In consequence, it is expected that smoker individuals are more prone to suffer periodontal diseases by reduction of the salivary peroxidase levels.

Instructions:Drag each tile to the correct box.
rjkz [21]
The correct sequence is sources emit greenhouse gases; global temperatures rise; snow and ice melt; and sea levels rise. The natural and man made sources emit greenhouse gases that are responsible for the greenhouse effect. The increase in the Earth's temperature due to these gases absorbing more heat from the sun caused climate change like melting of snow and ice which contributes to the rising sea levels.

Why does an energy transfer not always result in phase change?
elena-14-01-66 [18.8K]
These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. "If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.
