Answer:

Without the trees, water runs off rather than percolating into the

soil.

Explanation:

Flooding is the excessive flow of water due to increased rainfall. It usually deprives the soil of the affected area of essential nutrients. However, the presence of trees in an area can help prevent or reduce the possibility of flooding. The roots of large trees help hold the soil together, which improves the porousness of the soil. Also, trees store water that is meant to runoff.

Without the trees, the absorption or percolation of water into the ground/soil will be reduced, hence, the excess water runsoff the surface leading to flooding.

Point (7, 0)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{0+7}{7-0}$
[Fraction] Add/Subtract: $\displaystyle m=\frac{7}{7}$
[Fraction] Divide: $\displaystyle m=1$

Above 380C and below OoC the rate of photosynthesis decreases. Propose a hypothesis to explain why this occurs.

Effectus [21]

Answer:

Enzyme activity decrease at these temperatures. 

Explanation:

Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions. In light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH. In dark reactions carbon is fixed using the ATP and NADPH. 

The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about 10°c - 20°c. At low temperatures and high temperatures enzyme activity is less efficient.

At a temperature above 38°c and below 0°c enzyme activity decreases.
