How can a small change to the temperature of ocean water have a big effect on a tropical depression?
makkiz [27]
Heat waves can be dangerous, causing illnesses such as heat cramps and heat stroke, or even death. Warmer temperatures can also lead to a chain reaction of other changes around the world. That's because increasing air temperature also affects the oceans, weather patterns, snow and ice, and plants and animals.

What is the scientific name for a gorilla
Gnom [1K]
Gorillas are ground-dwelling, predominantly herbivorous apes that inhabit the forests of central Sub-Saharan Africa. The genus Gorilla is divided into two species: the eastern gorillas and the western gorillas (both critically endangered), and either four or five subspecies. They are the largest living primates. The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after the chimpanzees and bonobos.

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.
