Answer: so the Effect of Catalysts on the Activation Energy Barrier. Catalysts provide a new reaction pathway in which a lower A.E. is offered. A catalyst increases the rate of a reaction by lowering the activation energy so that more reactant molecules collide with enough energy to surmount the smaller energy barrier.hope this helps
The andwe is q high amounts of precipitation
When distance increases gravity decreases. Distance decreases then gravity increases. Directly proportional.
<u>Answer:</u>
The major type of weathering that takes place in a desert in Physical Weathering.
<u>Explanation: </u>
Physical weathering also known as mechanical weathering takes place in deserts. This weathering takes place due to physical or mechanical forces. Frost chattering, temperature fluctuation also causes physical weathering.
In the desert, there is a fluctuation in temperature. In deserts, the temperature during the day will be very high and at night the temperature will be very low. As a result, the rocks expand during daytime due to heating and at night the rocks undergo contraction due to the reduction in temperature. Hence the rocks are weakened followed by the disintegration or breaking of rock.
dN/dT = rK (K-N)/K
Here, K is carrying capacity
N = Population size
r = Intrinsic rate
dN/dT = 0.8*250 (1500-250)/1500
dN/dT = 166.66 that is equivalent to 167 animal in a year
Thus, in 2015, there would be 250 individuals and in 2016, there would be 260+167 = 417 animals.
