1. water temperature of lakes and rivers rise - nuclear power plant. Water is used as a coolant to maintain the temperature of nuclear reactors. and the resulting water is warmed up.

2.carbon monoxide pollutes air - internal combustion engine. Internal combustion engines release fumes of carbon monoxide.

3. fly ash of soot in air - coal-burning power plant. Coal burning plants release ash produced in small dark flecks.

4. soil contamination of water resources - DDT spraying in agriculture. DDT washes off agricultural land into water resources.

5. sewage contamination of water resources -population density. Urban areas produce a low of sewage, which is usually treated before being disposed of in rivers or the sea.

6. excess plant growth in the lakes or rivers - phosphate detergents. In many rivers, algal growth is limited by phosphate. Once excess phosphate is released to rivers, exponential algal growth can occur.

7.reduces farmland and plant life to cleanse air - urban sprawl. Urban sprawl uses up land for houses in an inefficient manner that could have been used for farming or natural areas.

8. studies air,water, and land - ecologist. Ecology is the study of relations of organisms to one another and to their physical surroundings.

The structure of a substrate P strongly resembles substrate Q. In an experiment, By mistake P was used instead of Q as a substra

Dvinal [7]

<h3>Answer;</h3>

C) P and Q have similar binding properties

<h3>Explanation;</h3>

Enzymes are biological catalysts that speeds up chemical reactions. Substrates are substances that are acted on by an enzyme to form a product.
An enzyme catalyzed reaction occurs when the substrate binds to the active site of an enzyme to form and enzyme-substrate complex.
Substrate P and Q are structurally similar which means they are in a position of binding and fitting in the active site of an enzyme. The strong structural similarity means that the binding properties of these two different substrates may be similar.
Formation of similar products or results when acted upon by an enzyme mean they are similar in terms of their binding properties, and thus the production of similar product.

In some areas of Florida, manatees gather near spring waters during cold weather because the temperature of the springs is alway

Alexxx [7]

From the data, the manatee population obviously increased after the regulations went into affect and the deaths due to watercraft reduced from 25 to 8 after the regulations were put into effect. The population increased by 165% from 1980=-2010 and the drop in deaths due to watercraft decreased by
68%.So this is not a direct correlation but at least it shows that the watercraft deaths decreased significantly. Since the population increased at a greater rate then it may be that more females were spared so could mate and give birth to that many more manatees.
