What was the impact of the use of fossil fuels during the industrial revolution?
IrinaK [193]

Impact of the use of fossil fuels during the industrial revolution was it made possible a huge increase in the amount of productive energy available to humans.

The development of machines, including steam engines and the internal combustion engine, made it possible to exploit vast new resources of energy stored in fossil fuels, specifically coal and oil. The fossil fuels revolution greatly increased the energy available to human societies during industrial revolution.

Contrary to this fossil fuel have some disadvantages like when fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.

In corn, smooth kernels (K) are dominant to wrinkled kernels (k).
Roman55 [17]

Heterozygous means 2 different zygotes. Since Smooth kernels are dominant, Zygotes KK and Kk will be smooth and kk will be wrinkled.

If you were to set up a Punnett Square chart like:

           K     k

   K   (KK)    (Kk)

   k   (Kk)     (kk)

the ratio for smooth to winkle would be  3 : 1

Which Will be 75% Smooth  and 25% Wrinkle

A population of kangaroos is growing at a rate of 2% per year, compounded continuously. If the growth rate continues, how many y
antoniya [11.8K]

Answer:

The correct answer is 20 years.

Explanation:

It is given that the growing rate is 2% or 2/100 = 0.02

This rate got increased to 150%

The formula for exponential growth is:  

A = Pe^rt

Let the initial population be 100%

150 = 100.e^0.02*t

3/2 = e^0.02t

1.5 = e^0.02t

After taking log from both the sides:  

ln(1.5) = 0.02t * ln(e) [ln(e) = 1]

ln(1.5) = 0.02t

t = ln(1.5)/0.02

t = 20.27

Thus, it will take around 20 years for the size of the population to reach 150 percent of its present size on the basis of the exponential growth function.
